Carps form the mainstay of aquaculture in India contributing over 85% of the total aquaculture production There are 61,259 species of vertebrates recognized world; over 30,700 are fish species of which 8,411 ore fresh water while 11,650 are marine. In India 2,163 spp. are fin fishes have been recorded from upland cold water (157; 7.26%) warm water of the plain (54; 20.99%), Brackish water (182; 8.41%) and marine environment (1,370; 63.43%). Some of these species are cultured at commercial level which covering a lot varieties of fin fishes The three Indian major carps, namely Catla (Catla catla), Rohu (Labeo rohita) and Mrigal (Cirrhinus mrigal) contribute the bulk of production to the extent of 75 to85 percent of the total fresh water fish production, the three exotic carp such as Silver carp (Hypophthalmichthys molitrix) and Common carp (Cyprinus carpio ), Grass carp (Ctenopharyngodon idella )form the second important group to incorporate several other medium and minor carp and into the carp poly culture system several method were used because of their region specific consumer preference and higher market demand.
History
Carp culture in India was restricted only to a homestead backyard pond activity in west Bengal and Odisha until late 1950 s with seed from riverine sources as the only input resulting low level of production the technological breakthrough breeding of carp through hypophysation in 1957 freshwater aquaculture of the country the country till 1984 virtually laid the foundation of scientific carp farming in the country.
Important characteristics of Indian major carps:-
Indian major carp grow fast and can reproduce even in artificial ponds. They feed upon phytoplankton, zooplankton, decaying organic matter, aquatic plant etc. stomach is absent in the alimentary canal of the major carps. Three types of Indian major carps are cultured in
Modern developments in transport technology are from two levels; one is from an understanding of internal physiological mechanisms of the fish and the optimal requirements, ensuring maximum survival of fish under transport and the other is from a study of the environmental parameters of the medium in which fish are transported. Under anaesthesia fish can be transported without water even, provided the skin and gills are kept moist under low temperature. The cryopreservation of fish sperm for use at any convenient time can be referred to here, though this would concern seed production more directly than live seed transport.
Nutritional requirement of cultivable fin fish: larvae, juveniles and adultsDebiprasad1997
Fish is among the healthiest foods on the planet. It is loaded with important nutrients, such as protein and vitamin D. Fish is also the world's best source of omega-3 fatty acids, which are incredibly important for human body and brain.
Manufactured feeds are an important part of modern commercial aquaculture, providing the balanced nutrition needed by farmed fish.
In the development of modern aquaculture, starting in the 1970s, fishmeal and fish oil were key components of the feeds for these species. They are combined with other ingredients such as vegetable proteins, cereal grains, vitamins and minerals and formed into feed pellets.
The global supply of fish meal and fish oil is finite and fully utilized. Alternative or nontraditional feedstuffs may differ in terms of taste, smell, texture, and color, as well as nutrient composition, from the traditional feedstuffs, which are produced largely from the natural prey of the fish being raised. Alternative feedstuffs may also contain compounds and antinutritional factors that affect digestive or sensory physiology.
Another important area of fish nutrition for the next 20 years will be larval fish nutrition. Currently, the cost and difficulty of rearing a great number of species from the first feeding to the juvenile stage are the most severe bottlenecks to the development of aquaculture production of nontraditional species.
Fish Culture or fish farming involves raising fish commercially in tanks or enclosures, usually for food. It is the principal form of aquaculture, while other methods may fall under mariculture. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species used in fish farming are carp, tilapia, salmon, and catfish.

FISH FARMING - ITS INCLUDES Fish Seed Production, Criteria for selection of suitable fish species, Groups of Freshwater Species, CULTIVABLE FISH SPECIES & FISH CUM DUCK FARMING
Introduction of Fish and Fisheries of India.
• Freshwater Fish: Fish that spend most or all of their life in freshwaters, such as rivers and lakes, having a salinity of less than 0.5 ppt. Around 40% of all known species of
fish are found in freshwater.
They may be divided into Coldwater Fish (5-20 °C); examples: Mahseer, Trout, etc., and Warmwater Fish (25 35 °C); example: Carps, Catfish, Snakeheads, Featherbacks, etc.
• Brackishwater Fish: Fish that can tolerate a wide range of salinity (0.5 30.0 ppt)
and live in backwaters, estuaries and coastal waters.
Example: Mullet, Milkfish, Seabass, Pearlspot, Mudskipper, etc.
• Marine Fish: Fish that spend most or all of their life in seawater, such as Seas and
Oceans, having salinity above 30 ppt. There are about 240 species contributing to
the marine fisheries. Example: Sardines, Mackerel, Ribbonfish, Anchovies, Grouper, Cobia, Tuna, etc.
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.
Indigenous fish species of Kashmir: Their importance, threats and conservation
Indigenous species are also called as native species. Indigenous species are found in a particular location and surrounding areas i.e., wide range of area. They are not restricted to a certain geographical area.
Gilgit-Baltistan (GB) has colossal normal blessing of freshwater assets. Its spouting waterways, singing streams and crisp water lakes have an extensive variety of local and extraordinary fish species. The frosty and crisp waters of GB are known to have 20 unique types of freshwater angle, including 17 locals and three exotics while four species are endemic to GB area. some of the fishes found in GB are Trouts (including brown, snow and rainbow trout), goldfish, crap fish and cat fish.
Hill areas offer good scope for the development- of fisheries—both for commercial and sport purposes.
The coldwater fishery resources in India comprise high and mid-altitude lakes, rivers, streams, their tributaries and reservoirs dammed across such rivers.
The importance of coldwater fisheries lies in their unique biodiversity, valuable germplasm and maintenance of environmental quality in hills.
Coldwater fishes breed naturally but since some species have been listed as endangered, therefore artificial breeding is now being practiced to restore the diversity.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

It is widely farmed as a component of a polyculture system of
three indian major carps, along with rohu & catla.
10. (B) MURREL FISHES
These are air breathing fishes with long
cylindercal body, flattened head and protractile
mouth.
These can grow in fresh water ponds, irrigation
canals, wells and marshy areas.
They breed even before the onset of monsoons.
12. 1. Channa punctatus or
Ophiocephalus : (Snake head)

at 5.5cm (1yr)
20. Adults found mainly in ponds, ditches, swamps and
marshes, but sometimes occur in muddy rivers.
Breed in confined waters during the monsoon months,
but can breed in ponds, when sufficient rain-water
accumulates.

other freshwater areas.
Adults fight well and provide good sport.
It is Carnivore fish.
Breeding occurs before the commencement of monsoons.
They are Oviparous fish.
23. (D)EXOTIC FISHES
When the indigenous fishnet are not favored for
culture due to economic viability, exotic breeds
are selected and cultured. These fishes yield
nutritious food and earn foreign exchange.
25. 1.Cyprinus carpio:(Common carp)
This fish was imported from China and introduced into
Nilagiri lakes.
The growth of the fish is higher and grows to a length
of 75cm and 6.5 kg weight.
It breeds thrice in a year. When cultured under
extensive system, the productivity was at 1500 kg/ha.

at a temperature range of 15° C to 20°C; eggs hatch in
4 days.
26. Adults often make considerable spawning migrations
to suitable backwaters and flooded meadows.
Individual females spawn with a few males in dense
vegetation.
The sticky eggs are attached to water plants or other
submerged objects.
Reproductive success is restricted to years when the
water level starts rising in May and when high
temperatures and flooding of terrestrial vegetation last
for a long period during May and June.
28. 2. Ctenopharyngodon idella:
(Grass carp)
It is native of Japan and China and was introduced
into Cuttack waters in 1959.

29. Adults occur in lakes, ponds, pools and backwaters of
large rivers, preferring large, slow-flowing or standing
water bodies with vegetation.
Tolerant of a wide range of temperatures from 0° to
38°C, and salinities to as much as 10 ppt and oxygen
levels down to 0.5 ppm.
Feed on higher aquatic plants and submerged
grasses; takes also detritus, insects and other
invertebrates.
One of the world's most important aquaculture
species and also used for weed control in rivers, fish
ponds and reservoir
31. 3. Hypothalamychthys molitrix:
(silver fish)

water of Cuttack region.
The mouth is located dorsally at the tip of snout, the body
is laterally compressed and enclosed by small shiny
scales.
It feeds on the left over food particles of carp fish and
grows quickly.
It reaches to a length of 60 cm and weighs about 1.5 kg.
Silver carp are usually farmed in polyculture with other
Asian carp, or sometimes with catla or other fish species.
32. (E) Cold Water Fishes
These fishes are commonly
called sport fishes.
These fishes include trouts and
Mahseers
34. 1. Salmogiardneri: (Rain bowtrout)
Oncorhynchus mykiss
Sometimes it is also caled as “steelhead trout”
It is a north American fish introduced into rivers and
lakes of Ooty and bill ranges of kerala.
The dorsal and caudal fins are pinkish with dark
spots.
It grows to a length of 1.8 m. and weigh upto 100kg.
Coloration blue to olive green above a pink band
along the lateral line and silver below
Coloration varies with habitat, size, and sexual
condition.
35. Female are able to produce upto 2,000/kg of body
weight.
Trouts will not spawn naturally in culture system, thus
juveniles must be obtained either by artificial
spawning in a hatchery or by collecting eggs from
wild stock.
monoculture is the most common practice in rainbow
trout culture, and intensive systems are considered
necessary in most situation to make the operation
economically attractive.
A potential site for commercial trout production must
have a year-round supply of high quality, that meets a
number of criteria.

Dorsal ride of the body is grayish green, lateral
sides are gold and belly is silvery white.
Even though it is adapted to grow well in canals
but now it is cultured in reservoirs.
It grows to a size of 1 mt. and considered as
good food fish.
Inhabit rivers and lakes, also in rapid streams
with rocky bottom. Grow better in a river with a
rocky bottom.
38. Travel toward headwaters at the start of
the rainy season and downstream at the
end of the rainy season.
Omnivorous, feed on filamentous algae,
chironomid larvae, water beetles and
crustaceans. Spawn from March to
September, over stones and gravel.
40. 3. Tor Khudree (Deccan mahseer)
Snout is pointed.
Body dark coloured on dorsal and lateral sides while
yellow on ventrolateral sides. Colour silvery or
greenish along the upper half of the body, becoming
silvery shot with gold on the sides.

41. The fish moves to upper reaches of small
streams to spawn.
They feed on plants, insects, shrimps and
mollusks.
Can be cultured in ponds and lakes. Regarded
to be of medicinal value.
Known to grow over a meter and 45 kg in
weight but have not been recorded in recent
times.
