Hybridization is the breeding between two different species or genera. This document discusses different types of hybridization in fish, including interspecific (between different species of the same genus), intergeneric (between different genera), and natural vs artificial hybridization. Interspecific hybridization in Indian major carp led to hybrids that exhibited faster growth than parents. Over 30 intergeneric hybrids were produced between catla, labeo, and cirrhinus genera. Natural hybridization is more common in freshwater fish due to overlapping habitats and spawning grounds. Factors like external fertilization and unchanged behavior can lead to natural hybridization. Artificial hybridization aims to combine desirable traits and is done by various methods like cohabitation and hormone

Marine Fisheries Regulation Act
An Act to provide for the regulation of fishing by fishing vessels in the sea along the coast line of the State. (1) This Act may be called the Kerala Marine Fishing Regulation Act, 1980. (2) It extends to the whole of the State of Kerala.
The primary requirement for successful carp breeding is proper brood stock management. Key aspects include maintaining brood ponds with suitable water quality and feeding the brood fish a balanced diet. During the breeding season, pituitary glands are collected from donor fish and extracts are prepared and preserved. The extracts are injected intramuscularly into mature brood fish based on their weight, with a provocative dose followed later by a higher final dose. This stimulates spawning, bypassing environmental variables. The injected fish are then placed together in breeding hapas inside brood ponds, where they spawn naturally. Their eggs are fertilized either naturally or through artificial methods like stripping and wet or dry insemination.

Traditional fishing Craft of India by Ashish sahuAshish sahu
Fishing crafts are most essential for catching the fish in large scale in water bodies. A large variety of crafts (boats) have been designed for marine and inland fishing in India. The types of fishing crafts of India falls under two general categories. These are Non –mechanized and mechanized fishing crafts.
Based on the topographical variations and difference in habits and habitats of fishing, different types of crafts and gears are used in various inland water system of India. The simplest and most primitive types of craft used for fishing in inland water are the rafts and songas, operated in calm water. In the larger rivers and estuaries subject to strong current and tidal movement, sturdier plank boats are used.

culture system - semi intensive, intensive, super intensice and cage.pptxHimanshuPatidar19
This document discusses different types of aquaculture systems including semi-intensive, intensive, and super intensive systems. It also discusses different cage culture systems used in aquaculture like fixed cages, floating cages, submersible cages, and submerged cages. Semi-intensive systems involve stocking fish at moderate densities and relying on natural foods supplemented with feed. Intensive systems rely on artificial feeds and management to maximize yields. Super intensive systems involve very high stocking densities and use of water treatment technologies like recirculating aquaculture systems.
Cage culture involves confining fish or shellfish within mesh enclosures in existing water bodies like ponds, rivers, and oceans. Some key advantages are the flexibility to use different water resources with minimal initial investment. However, there are also disadvantages like the need for complete diets, high risk of disease transmission due to crowding, potential for localized water quality issues, and limitations to production yields. Cage aquaculture has rapidly expanded in recent decades and continues to adapt to growing global demand through clustering cages and developing more intensive cage farming systems.

Fish farming involves raising fish commercially, usually for food. The most common fish species raised on farms are salmon, carp, tilapia, seabass, catfish, and cod. There is increasing demand for fish which has resulted in overfishing, so fish farming offers another source. Fish farms can be extensive or intensive. Extensive farms rely on natural food sources while intensive farms require artificial feeding and water treatment. Common fish farm systems include cages, ponds, composites of different fish species, and integrated systems that reuse water. Issues with fish farms include the use of wild fish in feeds and the high densities that can cause disease.

Aquaculture is the controlled process of rearing, breeding and harvesting of aquatic species, both animals and plants, especially for human consumption, though it is controlled aquatic environments like the oceans, lakes, rivers, ponds, and streams. It’s a similar conception to agriculture, but with fish instead of plants or livestock. It also serves various functions such as food production, restoration of threatened and endangered species populations, wild stock population enhancement, the building of aquariums, and fish cultures, and habitat restoration.
History of Aquaculture
The husbandry of fish is therefore not a new phenomenon. Ancient practices based on the modifications of natural bodies of water or wetlands to entrap young fish in enclosures until harvest have just evolved into more systematic and scientific methods and techniques.
Aquaculture has a long tradition, which is about 4 000 years, and form the beginning of the time man identified the importance of aquaculture.. Probably aquaculture began in China before very long ago, due to the wants of an emperor to have an unremitting supply of fish in his land. It is supposed that the proficiencies for keeping fish in ponds originated in China with fishermen who kept their extra catch alive temporarily in baskets submerged in rivers or small bodies of water created by damming one side of a river bed.(Ling, S.W,Aquaculture in Southeast Asia: A Historical Overview,A Washington Sea Grant Publication).
Another theory is that aquaculture arose from ancient practices for pinning down fish, with the operations steadily improving from trapping-holding to trapping-holding-growing, and finally into complete agriculture or farming practices.
Methods of Aquaculture
The methods of aquaculture’s farm-to-table process can differ from species to species. Generally, there are four stages of the production chain, starting in hatcheries and ending at the seafood counter in your grocery store. Four stages are:
stages of the production chain

Each of these stages may vary concerning its effect on the environment and the quality and safety of the seafood they produce.
The first stage in the aquaculture production chain is the hatchery. This is where the breeding of fish, hatch
1. Aquaculture production in Cambodia has grown significantly from 1610 tons in 1984 to 26,000 tons in 2005, driven mainly by expansion of inland freshwater pond and cage culture.
2. Inland aquaculture produces the majority of aquaculture output and relies heavily on culture of native fish species like Pangasius in cages and ponds, as well as introduced species like tilapia.
3. Mariculture and coastal shrimp farming have also developed but remain limited due to reliance on wild seed, lack of hatcheries and commercial feed, and high investment costs.
The document discusses the fishery industry in India, its present status, and future performance. It outlines the mission to sustainably grow Indian fisheries and aquaculture through research, education, and extension. It then lists numerous areas of focus for developing technologies to better manage fisheries, diversify aquaculture, improve fish health, and catalog genetic resources. The document concludes by highlighting several technologies that have already been developed and implemented to increase aquaculture production and improve post-harvest processing and quality.
The document discusses awareness training organized by Krish Viyan Kendra-Mallyal on subsidies available from the National Fisheries Development Board (NFDB) and other financial institutions for fishermen and entrepreneurs. It provides an overview of NFDB schemes and guidelines for various components of freshwater aquaculture development that NFDB assists with, including pond and tank construction, hatcheries, feed mills, and more. It also shares cost estimates and success stories of NFDB project implementation.
Freshwater aquaculture production has grown significantly worldwide in recent decades. The document discusses the definition and origins of aquaculture, noting that it originated much later than agriculture due to difficulties in appreciating aquatic environmental parameters. It provides statistics on global aquaculture production in 2009, with China as the top producer. The majority of production occurs in freshwater environments. Carps make up the largest portion by volume. India has considerable freshwater resources and biodiversity of cultured fish species, with carp culture being the main focus.
This document discusses pisciculture (fish farming). It begins with an introduction describing fish farming and hatcheries. It then describes the major categories of fish aquaculture as extensive and intensive. Specific types of fish farms are outlined, including cage systems, irrigation ditch/pond systems, composite culture, integrated recycling systems, and classic fry farming. The conclusion restates that fish farming involves raising fish commercially and that it provides an alternative to overfishing of wild fisheries due to increasing market demand.
Similar to RAJSTHAN PSC ( FISHERIES OBJECTIVE ) (20)
The principle of integrated fish farming involves farming of fish along with livestock or/and agricultural crops.. This type of farming offers great efficiency in resource utilization, as waste or by product from one system is
effectively recycled. It also enables effective utilization of available farming space for maximizing production.
•The rising cost of protein-rich fish food and chemical fertilizers
as well as the general concern for energy conservation have created awareness in the utilization of rice and other crop fields and livestock wastes for fish culture. Fish culture in combination with agriculture or livestock is a unique and lucrative venture and provides a higher farm income, makes available a cheap source of protein for the
rural population, increases productivity on small land-holdings
and increases the supply of feeds for the farm livestock.
Scope of Integrated Fish Farming
The scope of integrated farming is considerably
wide. Ducks and geese are raised in pond, and pond- dykes are used for horticultural and agricultural
crop products and animal rearing.
The system provides meat, milk, eggs, fruits,
vegetables, mushroom, fodder and grains, in
addition to fish.
Hence this system provides better production, provides more employment, and improves socio- economic status of farmers and betterment of rural economy.
Classification of Integrated Fish Farming
Integrated fish farming can be broadly classified into two, namely Agriculture-fish and Livestock-fish systems
Agriculture-fish systems- Agri-based systems include rice-fish integration,
horticulture-fish system, mushroom- fish system, seri-fish system.
Livestock-fish systems- Livestock-fish system includes cattle-fish system, system, pig-fish system, poultry-fish system, duck-fish system, goat-fish system, rabbit-fish system.
Integrated fish farming systems refer to the production, integrated management and comprehensive use of aquaculture, agriculture and livestock, with an emphasis on aquaculture. Asia has a long and rich history of integrated fish farming. Written records from the first and second centuries B.C. documented the integration of aquatic plant cultivation and fish farming. From the ninth century, records showed fish farming in the paddy field. From the fourteenth to sixteenth centuries, there were records of rotation of fish and grass culture; and by the 1620s, the mulberry-dike fishpond, the integration of fish and livestock farming and complex systems of multiple enterprises integrated with fish farming were developed. Integrated fish farming is the methods by which fish is cultured along with paddy, piggery, poultry or any livestock, or flower culture.
Fish Hatchery Management for Maintaining the Genetic Quality
Artificial propagation of fish species in hatcheries has been conducted on a large scale for several decades
In recent years, conservation hatcheries aims not only to produce fish for supplementing wild populations but also to preserve the genetic diversity and integrity of threatened or endangered species
Important considerations are maximizing genetic diversity and effective
population size while minimizing inbreeding and adaptation to captivity
Objective
To maintain the genetic diversity, effective population size and to minimize inbreeding
This document discusses mud crab and lobster culture in India. It provides information on the four main species of mud crabs found in the Indo-Pacific region - Scylla serrata, S. olivacea, S. tranquebarica, and S. paramamosain. Mud crab farming is done commercially using grow-out and fattening methods in ponds. Three commercially important lobster species for India are also described - Panulirus polyphagus, P. homarus, and P. ornatus. Their life cycles and biology are summarized. Lobster farming can be done by growing juveniles in ponds to market size or fattening medium sized lobsters. Optimal water
Groupers belongs to the family Serranidae.
⚫ Groupers are classified in 14 genera of the subfamily Epinephelinae, which comprises at least half the approximately 449 species in the family Serranidae.
⚫ Several grouper species have been raised on a commercial scale, but mostly by growing out captured wild juveniles.
cage-culture
Culture of fishes in meshed boxes placed in water is called cage culture.
It is an intensive method of aquaculture.
Cage culture is practiced in areas where there is sufficient water movement.
It is done in river, lakes, estuaries & seas.
Asian sea bass (Lates calcarifer) is an important species for aquaculture in Southeast Asia. It can be cultured in both freshwater and saltwater. Major issues in sea bass culture include cannibalism in young stages, dependence on high protein feed sources, and unpredictable wild fry availability. Sea bass nursery rearing is typically done in earthen ponds, concrete tanks, or net cages with fry stocked at high densities. Grow-out is usually done in ponds or cages at lower stocking densities, feeding on trash fish. Sea bass polyculture with tilapia is also common, with sea bass reaching market size of 600g within 4-5 months.
This document provides information on the breeding and seed production of various catfish and trout species that have potential for aquaculture in India. For most species, captive broodstock are raised and induced to breed using hormones. Eggs are hatched and larvae reared with live feeds before weaning onto formulated feeds. Breeding technologies have been adopted to produce seed for farming of species such as magur, singi, pabdah catfish and rainbow trout. Overall, the document outlines best practices for induced breeding, hatchery and nursery rearing of important fish species.
Wetlands are... areas where a water table is at, near, or just above the surface
and where soils are water-saturated for a sufficient length of time such that excess
water and resulting low soil oxygen levels are principal determinants of vegetation
and soil development. wetlands will have a relative abundance of obligate
hydrophytes in the vegetation community and soils featuring “hydric” characteristics.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
This document provides information about ornamental fish culture and the ornamental fish industry. It discusses how ornamental fish keeping began as a hobby and has grown into a large international business. Key points include:
- Ornamental fish production is an important part of the aquaculture industry and global ornamental fish trade is estimated at over $14 billion.
- Over 1,800 species of ornamental fish are in the market, with over 1,000 from freshwater origins. Major suppliers include Singapore, Thailand, and Hong Kong.
- India's ornamental fish industry is small at 1% of global trade but is growing at 14% annually. Tamilnadu, Kerala and West Bengal are major producers.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function.

in the subfamily Cyprininae. Cyprininae have a large distribution (Africa,
Northern America, Southern Central America to Guatemala, Asia and
Europe), but the Labeos occur only in Africa and South-East Asia. The Labeo
lineage is the second most important group of cyprinid fishes after the
Barbiinae, and in Asia, it represents about 19.6% of the cyprinid species
composition. The genus Labeo (Cuiver, 1816) with approximately 103
species around the world is arguably the most dominating group of the
Cyprinidae family. This genus is represented by 28 species widely distributed
throughout South and South-East Asia. In many regions, an increasing
importance of Labeo as food fish is noted. Also being widely cultivated as a
part of aquaculture, some of the species of this genus are reared for
ornamental purpose, some as food species, some for extracting oil and some
are considered to be of medicinal value also. This genus is a column and
bottom feeder and feeds on algae, small fishes and crustaceans.
Labeos can be distinguished from the other geneses of this family
because of their unique characters bearing thick-lipped and sucking mouth on
the underside of the head with two to four small barbels. The diagnostic
characters of the genus Labeo are well known and accurate.

The dorsal profile of Labeo bata is slightly more convex than that of the
abdomen and its greatest width of the head equals its length excluding the
snout. The lips are thin, continuous and the lower one is reflected from off the
mandible and with a shallow groove along its hind edge. There is a presence
of tubercle inside the lower jaw above the symphysis. They have a short pair
of maxillary barbels. Teeth are pharyngeal, plough shaped or molariform. The
dorsal fin is as high as the long head with a concave upper edge and the
pectoral fin is almost as long as the head and reaches the ventral which is
rather shorter. The caudal fin was observed to be deeply forked. It is a bentho-
pelagic and potamodromous species, which inhabits rivers. It is a herbivorous
column feeder.
Labeo calbasu (Hamilton, 1822)
B. iii, D. 16, P. 18, V. 8, A. 6, C. 18, L. I. 42, L. tr. 7. Barbels 4.
Labeo calbasu is commomly known as Kallot. The width of the head
equals its length excluding the snout. The mouth is rather narrow with obtuse
and depressed snout. The lips are thick and fringed and each has a distinct
inner fold. They have very short gill rakers. Two pairs of barbels are present.
The dorsal fin commences in advance of the ventrals and midway between the
snout and the base of the deeply forked caudal. Colour is blackish but
17. 3
occasionally the upper lobe of the caudal is white. It occurs in rivers and
ponds; in slow-moving waters of rivers and it is essentially a bottom feeder
that feeds on plants, filamentous algae and diatoms.
Labeo rohita (Hamilton, 1822)
B. iii, D. 13, P. 18, V. 9, A. 8, C. 18, L. I. 44, L. tr. 8. Barbels 2
Labeo rohita is commomly known as Rohu. The diameter of the eyes is
4 to 6 in the length of the head, 1 1/2 to 2 diameters from end of the snout and
3 are apart. The inter-orbital space is flat. Dorsal profile more convex than
that of the abdomen, it is a little concave over the orbit. The greatest width of
the head equals its length excluding the snout. The snout is obtuse and
depressed, scarcely swollen but projects beyond the jaws. Lips are thick and
fringed and with a distinct inner fold above and below. The gill rakers are stiff
and are half as long as the eye. There is a short and thin maxillary pair of
barbel.
It is the natural inhabitant of freshwater sections of the rivers and
thrives well in all fresh waters below an altitude of approximately 549 m. It is
a bottom feeder and prefers to feed on plant matter including decaying
vegetation and attains maturity towards the end of the second year in ponds.
The spawning season of rohu generally coincides with the southwest
monsoon. Spawning takes place in flooded rivers.

2. Mastacembelus armatus (Lacepede, 1800)
Kingdom : Animalia
Phylum : Chordata
Class : Actinopterygii
Order : Synbranchiformes
Family : Mastacembelidae
Genus : Mastacembelus
Species : Mastacembelus armatus
D1.33-38/ D2.64-94, P.21-25, D2
It is commonly known as tire-track spiny eel or zig-zag eel. It is
vernacularly known as baim/bami/baam in India. Mastacembelus armatus is
widely distributed in India, Bangladesh, Pakistan, Nepal, Sumatra, Sri Lanka,
Thailand, Vietnam, Indonesia, Myanmar, Malaysia, Southern China and other
parts of South East Asia. It occurs in a variety of freshwater habitats in the
plains as well as in hills of India. It mainly inhabits rivers, canals, beels,
ponds and inundated fields. It also occurs in still waters, both in coastal
+A+ C.3/167-178.
Mastacembelus armatus is a common fish species of Indian
subcontinent. It belongs to the family Mastacembelidae under the order
Synbranchiformes. It is one of the most popular table fishes with delicious
flesh quality having a special flavor, characteristic texture and high protein,
oil and vitamin C content [1-3]; and thus has a good market demand. In
northern and eastern India, the fish is very popular when sold alive. It is also
popular as an aquarium fish due to its attractive color pattern and has high
demand among the aquarium fish hobbyists
19. 5
marshes and dry zone tanks; occasionally this fish species stays in partly
buried condition under fine substrate.
The body of Mastacembelus armatus is slender, elongated and slightly
compressed. The maxilla reaches below the front edge of the eye. Pre-opercle
is with 2 or 3 spines which are usually conspicuous, but often one or more
may be embedded in skin. Pre-orbital spine is strong and is usually piercing
the skin. The mouth is a transverse crescentic slit; bounded by an upper and a
lower labial fold. The upper jaw extends anteriorly in front of the lower and
participates in the formation of the tri-lobed snout, consisting of a median
stiff, solid and pointed process and two lateral soft, hollow and blunt
projections. On the floor of bucco-pharynx, a triangular tongue consisting of
the glossohyal enclosed in a thick mucous membrane is present. Teeth are
present on the jaws and pharynx; no vomerine and palatine teeth are present.
Teeth are sub equal, short, pointed, inclined inwards and arranged in patches.
Fin: Long dorsal and anal fin is present which are confluent with the caudal
fin. Spinous dorsal fin is inserted above middle or posterior third of the
pectoral fins. Last dorsal spine is small and hidden beneath the skin. Color:
Dark brown in color becomes lighter on the abdomen and usually with zig-
zag lines; sometimes connecting to form a network but almost never
extending onto abdomen. A blackish band is present which goes through the
eye and is continued in an undulating course along the upper half of the side
to the caudal fin. Above this band, there is a row of black spots along the base
of the soft dorsal fin and a short black band over the back under dorsal spines.
Pectoral fins are usually spotted; dorsal and anal fins are usually banded or
spotted.
Observing the well-developed dentition, absence of gill rakers, strongly
built stomach and short intestine, together with the dominance of animal
matter in the gut contents, It is reported the carnivorous and active predatory
habit of Mastacembelus armatus. Freshwater shrimps (Macrobrachium spp.),
dipteran larvae, brine shrimps (Brachipus sp.), earthworms (aquatic
oligochaetes) and minor carps (cyprinids) have been reported as preferred
food items in order of their frequency of occurrence in the gut.
20. 6
Male and female of Mastacembelus armatus can only be distinguished
during the breeding season observing some particular characters; males are
active and brighter in color while females are potbellied and dull in color. On
putting slight pressure on abdomen, milt comes out in males while eggs ooze
out in case of females.
3. Nile tilapia - Oreochromis niloticus (Linnaeus, 1758)
D XVI-XVIII, 12-14, A III, 9-11.
Kingdom : Animalia
Phylum : Chordata
Class : Actinopterygii
Order : Cichliformes
Family : Cichlidae
Genus : Oreochromis
Species : Oreochromis niloticus (Lin.)
Body shape generally laterally compressed to oval and deep, though
variable depending on the environment. Lateral line interrupted with 30-34
cycloid scales. Mouth terminal. Gill rakers on lower limb of first gill arch 20-
26. Vertebrae 30-32. Caudal fin has 7-12 distinct vertical stripes. Breeding
males with red flush to head, lower body, dorsal and caudal fins. Caudal fin
truncate. Genital papillae of male short and conical or bluntly bifid at tip and
not tessellated. Teeth in the jaws in 3 to 7 series, the number of which is size
dependent. The outermost teeth are bicuspid and in adults with stout shafts
21. 7
and obliquely truncate major cusps. Lower pharyngeal with firm teeth in
approximately triangular dentigerous area. The most diagnostic features are
the regular and definitive stripes on the caudal fin, the red flush of the
breeding male and the dark margin of the dorsal fin. Body colouration varies
depending on environmental, physiological and dietary factors.
Sexual maturity is reached at 10-30 cm TL and is related to the
maximum size attained in a given population and condition, which in turn is
determined by food availability and temperature. Reproduction occurs only
when temperature exceeds 20 °C. The breeding cycle is latitude dependent
and spawning becomes more seasonal at higher latitudes. In many instances
the breeding cycle is synchronized with the rainy season. The species is a nest
building, batch spawning mouth brooder that can spawn every 30 days. The
nest, like in many tilapiine fishes, is a circular depression in sandy areas of up
to 1m in diameter and 0.5 m deep. The average nest diameter is twice the
length of the male making it. Males are highly territorial and defend their
nests. Batches of eggs are spawned into the nest, fertilized externally and then
picked up by the female. The female incubates the eggs for 5-7 days when
they hatch and the early juveniles remain in the mouth until after yolk sac
absorption. Depending on size, females can carry up to 200 eggs. The eggs
are large and ovoid (pear shaped) and at hatching the fish are around 4mm in
length.
4. Macrobrachium rosenbergii (De Man, 1879)
Phylum : Arthropoda
Subphylum : Crustacea
Class : Malacostraca
Order : Decapoda
Infraorder : Caridea
Family : Palaemonidae
Genus : Macrobrachium
Species : Macrobrachium rosenbergii
22. 8
Macrobrachium rosenbergii, also known as the giant river
prawn or gaint Fresh water prawn, is a commercially important species of
palaemonid freshwater prawn. It is also known as the Malaysian prawn or
freshwater scampi. It is found throughout the tropical and subtropical areas of
the Indo-Pacific region, from India to Southeast Asia and Northern
Australia. The giant freshwater prawn has also been introduced to parts
of Africa, Thailand, China, Japan, New Zealand, Americas and Caribbean. It
is one of the biggest freshwater prawns in the world and is widely cultivated
in several countries for food. While M. rosenbergii is considered a freshwater
species, the larval stage of the animal depends on brackish water. Once the
individual prawn has grown beyond the planktonic stage and becomes a
juvenile, it will live entirely in freshwater.
M. rosenbergii is a striking looking prawn in which the second pair of
walking legs can really justify the genus name meaning ‘large arms’. In the
males these walking legs can have a vibrant shade of blue and can also be
twice the body length. The largest males can attain a total length from tip of
rostrum to the end of the telson of 320 mm compared to 250 mm for the
largest females.
23. 9
In general, the body form is typical of a decapod crustacean with the
head and thorax fused into a cephalothorax. The rostrum at the front end of
the cephalothorax is very prominent with 11-14 dorsal teeth and 8-10 ventral
teeth. Another distinctive feature of the adult male is that the moveable finger
of the second walking leg or cheliped is covered in tightly packed long setae
that give a velvety appearance to the appendage. The first ‘walking leg’ is not
readily visible being very long and delicate in form but tightly folded up
under the cephalothorax and functions as a feeding appendage with fine
forcep-like chelae at their tips.
Males can attain larger size than females and in dominant males the
second walking legs are much longer and thicker. The abdomen of the male is
narrower and the female, as well as having a wider abdomen, has longer
pleura (the overlapping plates of cuticle extending from the exoskeleton) and
these combined form a chamber for incubating the eggs carried on the
pleopods. The male genital openings are on the fifth walking legs and the
females genital pores are on the third walking leg.
The colours of M. rosenbergii can vary according to where the prawns
are found but the body can be greenish-grey. In small individuals, delicate
striping on the cephalothorax can be seen but these markings are not apparent
in tank-reared specimens. The chelipeds of dominant males are bright blue but
more yellowish in non-dominant males and females. The ventral side is pale
and translucent.
In mating, the male deposits spermatophores on the underside of the
female's thorax, between the walking legs. The female then extrudes eggs,
which pass through the spermatophores. The female carries the fertilised eggs
with her until they hatch, the time may vary, but is generally less than three
weeks. Females lay 10,000–50,000 eggs up to five times per year. From these
eggs hatch zoeae, the first larval stage of crustaceans. They go through several
larval stages before metamorphosing into post-larvae, at which stage they are
7.1–9.9 mm long and resemble adults. This metamorphosis usually takes
place about 32 to 35 days after hatching. These post-larvae then migrate back
into fresh water.

5. White legged shrimp, Litopenaeus vannamei (Boone, 1931)
Phylum : Arthropoda
Subphylum : Crustacea
Class : Malacostraca
Order : Decapoda
Suborder : Dendrobranchiata
Family : Penaeidae
Genus : Litopenaeus
Species : Litopenaeus vannamei
Shrimp farming in India, till 2009, was synonymous with the mono
culture of tiger shrimp, Penaeus monodon. Since 1995 culture of Penaeus
monodon is affected by White Spot Syndrome Virus (WSSV) and the
development of shrimp farming has been stagnant. Most of the South East
Asian countries like Thailand, Vietnam, Indonesia were also culturing
Penaeus monodon and since 2001-02 onwards most of them have shifted to
culture of exotic Whiteleg shrimp, Litopenaeus vannamei because of the
availability of Specific Pathogen Free (SPF) and Specific Pathogen Resistant
(SPR) brood stock. In India, Pilot-scale introduction of Litopenaeus
vannamei was initiated in 2003 and after a risk analysis study large-scale
introduction has been permitted in 2009.
25. 11
Litopenaeus vannamei is native of pacific coast of Mexico and Central
and South America as far south as Peru. It is mainly found on mud bottoms,
down to a depth of 75 m. It is commonly known as white legged shrimp or
Mexican white shrimp. It is greyish-white in color. The maximum weight of
the females in the wild is about 120 g. The males are smaller at 60-80g. It
lives in the column and prefers clayey loam soil.
For Litopenaeus vannamei the growth at 30°C is much higher than at
25°C. The optimal range of temperature for the species is between 30 and
34°C. At 20°C growth virtually stops. It can tolerate salinity levels of 0 to 50
ppt. Growth is uniform within 10-40 ppt. They can grow in fresh water also
but the growth is slower below 10 ppt. pH range of 7 to 9 is tolerated with
optimal growth at pH 8.0. Dissolved oxygen levels above 4.5 ppm are
required for optimal growth. Turbid water with flocculated particles of more
than 0.5 micron resulted in better growth than clean water mainly because of
the presence of algae and bacteria. Ammonia -N and Nitrite - N levels should
be less than 0.1 ppm and 1 ppm respectively.
It is an omnivorous scavenger and is less aggressive and less
carnivorous than Penaeus monodon. Food intake is more during evening and
night. Retention time of food in the gut is 2.2 to 5 hours. Growth of
Litopenaeus vannamei, under confined culture conditions is similar to
Penaeus monodon till they attain 20g size. Beyond that the growth rate was
poor. The shrimps attained the size of 20g within a period of 100-120 days
depending on the stocking density.

6. Biofloc culture
It is an innovative and cost-effective technology in which toxic
materials to the fish and shellfish such as Nitrate, Nitrite, Ammonia can be
converted to useful product, ie. proteinaceous feed. It is the technology used
in aquaculture system with limited or zero water exchange under high
stocking density, strong aeration and biota formed by biofloc.The culture of
biofloc will be productive in the case of culture tanks exposed to sun.
Biofloc system was developed to improve the environmental control
over the aquatic animal production. In aquaculture, the strong influential
factors are the feed cost (accounting to 60% of the total production cost) and
most limiting factor is the water/land availability. High stocking density and
rearing of aquatic animals requires wastewater treatment. Biofloc system is a
wastewater treatment which has gained vital importance as an approach in
aquaculture.
The principle of this technique is the generation of nitrogen cycle by
maintaining higher C: N ratio through stimulating heterotrophic microbial
growth, which assimilates the nitrogenous waste that can be exploited by the
cultured spices as a feed. The biofloc technology is not only effective in
treating the waste but also grants nutrition to the aquatic animal.
27. 13
The biofloc technology has been implemented in shrimp farming due to
its bottom dwelling habit and resistance to environmental changes. Studies
have been conducted to assess the larval growth and reproductive
performance of shrimps and Nile tilapia. An improved breeding performance
was observed in shrimp reared in the biofloc system when compared to that of
normal culture practices. Similarly improved larval growth performance was
also noticed.
Biofloc is a heterogeneous aggregate of suspended particles and variety
of microorganisms associated with extracellular polymeric substances. It is
composed of microorganisms such as bacteria, algae, fungi, invertebrates and
detritus, etc. It is a protein-rich live feed formed as a result of conversion of
unused feed and excreta into a natural food in a culture system on exposure to
sunlight. Each floc is held together in a loose matrix of mucus that is secreted
by bacteria and bound by filamentous microorganisms or electrostatic
attraction. Large flocs can be seen with the naked eye, but most of them are
microscopic. Floc size range from 50 – 200 microns.
A good nutritional value is found in biofloc. The dry weight protein
ranges from 25 – 50 percent, fat ranges 0.5 – 15 percent. It is a good source of
vitamins and minerals, particularly phosphorous. It also has an effect similar
to probiotics. The dried biofloc is proposed as an ingredient to replace the
fishmeal or soybean in the feed. The nutritional quality is good; however,
only limited qualities are available. Furthermore, the cost-effectiveness of
producing and drying biofloc solids at a commercial scale is a challenge.
Benefits of Biofloc culture system
Eco-friendly culture system. It reduces environmental impact. Improves
land and water use efficiency. Limited or zero water exchange. Higher
productivity (It enhances survival rate, growth performance, feed conversion
in the culture systems of fish). Higher biosecurity. Reduces water pollution
and the risk of introduction and spread of pathogens Cost-effective feed
production. It reduces utilization of protein rich feed and cost of standard
28. 14
feed. It reduces the pressure on capture fisheries ie., use of cheaper food fish
and trash fish for fish feed formulation.
Disadvantages of Biofloc Technology
Increased energy requirement for mixing and aeration. Reduced
response time because water respiration rates are elevated. Start-up period
required. Alkalinity supplementation required. Increased pollution potential
from nitrate accumulation. Inconsistent and seasonal performance for
sunlight-exposed systems
7. Gonadosomatic index
The Gonadosomatic index ( GSI), is the calculation of the gonad mass
as a proportion of the total body weight. It is represented by the formula –
GSI = [gonad weight / total tissue weight] × 100
The Gonadosomatic index measured as egg output per unit weight,
decreases interspecifically with female size in fishes (Sadovy, 1996). The
frequency of spawning also decreases with species size, with smaller species
much more likely to be daily spawners. One way to consider more periodic
spawning, whether it is restricted to a lunar period or a yearly period, is that
the benefits for spawning at a particular time of year outweigh two potential
costs: not surviving to the next reproductive period, and morphological
limitations on how many eggs can be developed at a given time. For larger
species, lower instantaneous mortality rates could lessen any costs of delaying
reproduction, tipping the balance in favor of seasonal reproduction.
8. Ponderal index
The Ponderal index (PI) or The Corpulence index (PI) is a weight-
height related parameter that is mainly used to assess the pattern of fetal
growth in small-for-gestational age infants. The PI was calculated by using
the following formula -
29. 15
PI = weight (in grame) x 100/(height3
in cm).
It is also known as measure of leanness of a person,
1. Demonstration of agricultural technology to farmers and extension
workers.
calculated as a
relationship between mass and height. It was first proposed in 1921 as the
"Corpulence measure" by Swiss physician Fritz Rohrer and hence is also
known as Rohrer’s Index.
9. TOT : Transfer of Technology
The major objective of Indian Council of Agriculture Research (ICAR)
is to disseminate the useful research results of the research stations to farmers.
It may be noted that all research findings are not technology.
Technology has been defined by Dr. V.E. Subrathanam in 1987 as “The
research findings which are having some practical utility, tested and found
economically feasible, socialiy acceptable, culturally adaptable, scale neutral,
gender neutral and eco-friendly as per the farmers conditions are considersd
technologt”
Transfer of Technology (TOT) is defined, as “the movement of relevant
agricultural information a research centre (source of technology) or
innovation system through an extension system to the clients system, that is
the target group of farmers who are expected to adopt and integrate the new
technology into the existing farming systems and practices (Mutharamman,
1994).
The first line extension projects of ICAR serves the following specific
purposes:
2. Constraints identification by testing and verifying technologies.
3. Feedback to scientist for reorientation of research, education and
training.
4. Development of extension models for large scale multiplication.
30. 16
5. Training and communication support to state government, Agricultural
Departments and NGOs.
The ICAR launched from time to time Transfer of Technology
Programmes. These were-
1. National Demonstration Project – 1964
2. Operational Research Project – 1975
3. Krishi Vigyan Kendras – 1974
4. Lab to Land Programme – 1979
Realizing the scope and importance of integrated working of
interrelationship between research, education and extension functions, the
ICAR Established a Section of Extension Education at its headquarters in
1971, which was later on strengthened and renamed as Division of
Agricultural Extension. It was intended to enforce this functional relationship
down the line in the research institutes, agricultural universities and allied
institutions.
10. KVK: Krishi Vigyan Kendra
Based on the recommendations (1964-65) and Mohan Sinha Mehta
committee constituted by ICAR, the year 1974 witnessed a new type of
experimentation in the history of Indian agriculture. The vocational training in
agriculture was imparted to the farmers with the establishment of first Farm
Science Centre at Pondicherry, later on named as Krishi Vigyan Kendra.
The basic concepts of KVK are-
1. The centre will impart learning through work experience and hence,
will be concerned with technical literacy.
2. The centre will impart training only to those extension agents who
are already employed or practising farmers and fishermen.
3. There will be no uniform syllabus for a KVK. The programmes of
each centre will be tailored according to felt needs, natural resources
and the potentials for agricultural growth in that particular area.
31. 17
The three fundamental principles of KVK programmes are-
1. Agricultural production as the prime goal
2. Work experience as the main method of imparting training
3. Priority to weaker sections of the society, are the backbone of the
KVK programme.
The main objectives of the KVK is to provide a strong training
support for bringing about production breakthrough in agriculture. The
specific objects are –
1. Plan and conduct survey of the operational area to prepare the
resource inventory and to identify the training needs of the farming
community.
2. Plan and conduct production oriented, need based and long duration
training courses.
3. Conducting first-line demonstrations on the latest farm technologies
in the interest of the farmers, extension workers and the scientists.
4. Organise on-farm research for assessment and refinement of
technologies and constraint analysis.
5. Provide training facilities in homemaking and nutrition education
for rural community etc.
The objective stated here are common for all the KVKs, In addition,
each Krishi Vigyan Kendra has some mandates. Mandate means a specific set
of responsibilities to perform. The mandate of a KVK is unique for it and is
determined on the basis of the most important needs of the clientele, their
resources and constraints, and nature of the ecosystem. The success of a KVK
is judged by the extent to which it fulfills its obligations specified in the
mandate.
With effoct from 1st
April, 1992, all first-lkine Transfer of Technology
Projects of ICAR viz. National Demonstration (ND), Operational Research
Project (ORP) and Lab to Land Programme (LLP) have been integrated with
the KVKs. In the reorganized system, the major Mandates of the KVK are to
conduct-
32. 18
i) Training Programmes – The most important function of the KVKs is
to conduct need based training progamme in agriculture and allied
vocation to impart firsthand knowledge ans skills to the farmer, farm
women, rural youth and extension functionaries.
ii) Frontline Demonstrations – The field demonstration conduvted under
the close supervision of the scientist of the National Agricultural
Reseach System are called frontline demonstrations, because the
technologies are demonstrated for the first time by the scientist
themselves. The objective is to demonstrate newly released crop
production and protection technologies in the farmers’ field.
iii)On-farm Testing – These are conducted on the farmers’ field on such
problems where the appropriate technologies are not available for
particular agro-climatic situation and the main objectives are problem
diagnosis, planning and experimentation.
As the KVK continued to gain strength and spread, its mandates also
changed with time. These changes are - (i) When the KVK was started in
1974, the important mandate was to impart vocational training in agriculture.
(ii) During 1990s focus shifted to on-farm testing and demonstration of
technologies. (iii) During the tenth Plan (2002-2007) the mandate shifted to
technologies assessment and refinement, and (iv) During the Eleventh Plan,
KVKs would work as knowledge and resource centre of agricultural
technology.
The KVKproject is sponsored by the ICAR and is implemented by
ICAR institute, agricultural universities, selected voluntary organizations and
state department of agriculture. Monitoring and evaluation of large number of
KVKs are a challenging task. The State Agricultural Universities (SAU), have
been involved by entrusting the responsibilities of overseeing the KVKs by
the Director of Extension of SAUs.
KVKs have become a brand name, not only in India, overseas also.
Over the years the ICAR has strengthened the KVK system as an innovative
institutional model for assessment, refinement and demonstration of
agricultural technologies. KVKs are playing an important role in the
33. 19
development of agriculture and allied sector. With the strengthening of KVKs
during 12th
A self-help group may be registered or unregistered. It typically
comprises a group of micro enterpreneurs having homogeneous social and
economic backgrounds, all voluntarily coming together to save regular small
sums of money, mutually agreeing to contribute to a common fund and to
meet their emergency needs on the basis of mutual help. They pool their
resources to become financially stable, taking loans from the money collected
by that group and by making everybody in that group self-employed. The
group members use collective wisdom and peer pressure to ensure proper
end-use of credit and timely repayment. This system eliminates the need for
collateral and is closely related to that of solidarity lending, widely used by
Plan, KVKs are playing important role in promoting integrated
farming system comprising animal component, fishery component, processing
and value addition.
At present, there are 706 KVKs in India. While in Rajasthan, there
are 42 KVKs, out of which 33 are under State Agricultural Universities
(SAU), 3 under ICAR, 4 under NGOs and remaining 2 under Other
Educational Institutions (OEI). KVK, Banswara (MPUAT, Udaipur) is well
known in the activities for carps seed production and ornamental fish
production. KVK, Sriganganagar (RAU, Bikaner) is also popular in fish
rearing and training programmes to farmers.
11. SHG : Self Help Groups
A self-help group (SHGs) is a financial intermediary committee usually
composed of 10–20 local women or men. SHG is nothing but a group of
people who are on daily wages, they form a group and from that group one
person collects the money and gives the money to the person who is in need.
Members also make small regular savings contributions over a few
months until there is enough money in the group to begin lending. Funds may
then be lent back to the members or to others in the village for any purpose. In
India, many SHGs are 'linked' to banks for the delivery of micro-credit.
34. 20
microfinance institutions. To make the book keeping simple, flat interest rate
are used for most loans.
Self-help groups are started by governmental organizations that
generally have broad anti-poverty agendas. These groups are seen as
instruments for goals including empowering women, developing leadership
abilities among poor and the needy people, increasing school enrolments and
improving nutrition and the use of birth control. In India, SHGs bridge the
gap between high-caste & low-caste people /citizens.
Financial intermediation is generally seen more as an entry point to
these other goals, rather than as a primary objective. This can hinder their
development as sources of village capital, as well as their efforts to aggregate
locally controlled pools of capital through federation, as was historically
accomplished by credit unions.
Under “NABARD-SHG Bank Linkage” programme, borrow from
banks once they have accumulated a base of their own capital. This model has
attracted attention as a possible way of delivering Micro-finance services to
poor populations that have been difficult to reach directly through banks or
other institutions. By aggregating their individual savings into a single
deposit, SHGs minimize the bank's transaction costs and generate an
attractive volume of deposits. Through SHGs, the bank can serve small rural
depositors while paying them a market rate of interest. Organization like
SHGs can be an effective tool for "allevating poverty.
Advantages of financing through SHGs are -
i) An economically poor individual gains strength as part of a group.
ii) Besides, financing through SHGs reduces transaction costs for both
lenders and borrowers.
iii)While lenders have to handle only a triple SHG account instead of a
large number of small-sized individual accounts, borrowers as part of
an SHG minimize expenses on travel (to and from the branch and other
places) for completing paper work and on the loss of workdays in
canvassing for loans.

iv) SHGs have significantly empowered poor people, especially women, in
rural areas.
v) SHGs have helped immensely in reducing the influence of informal
lenders in rural areas.
vi) Many big corporate houses are also promoting SHGs at many placesin
India.
vii) SHGs help borrowers overcome the problem of lack of collateral.
Women can discuss their problem and find solutions for it.
