3.Experience of hatchery technicians
4.Efficiency of operational management.
Importance of biofilm biofloc and pheriphytons in aquatic health management
Biofilms, bioflocs, and periphyton play an important role in aquatic health management. Biofilms are assemblages of microbes that form irreversibly on surfaces. Bioflocs are protein-rich aggregates of organic material and microorganisms that provide shelter and food for cultured organisms. Periphyton is a complex mixture of algae, bacteria, and detritus attached to submerged surfaces that serves as an important food source and improves water quality through nutrient removal. All three help enhance the growth and survival of aquatic organisms while improving environmental conditions.
Soil Parameters in Fish Health
Soil is an important ecological factor for aquatic environments and ponds. It is the main source of nutrients through decomposition of detritus by microbes like algae and bacteria. This enhances pond productivity and supports bottom-dwelling organisms that fish prey on. Key soil properties that influence suitability for fish culture include pH, organic carbon, phosphorus and nitrogen levels, carbon to nitrogen ratio, texture and water holding capacity. Optimal ranges are pH of 6.5-7.5, over 1% organic carbon, phosphorus and nitrogen above 10 mg/100g and 6 mg/100g respectively, and a carbon to nitrogen ratio of 10-15.

Penaeid shrimp are an important fishery for India, providing livelihoods and being a major seafood export. They belong to the class Crustacea and order Decapoda. The most important species caught off India include Fenneropenaeus indicus, Penaeus monodon, P. semisulcatus, and Solenocera spp. Penaeid shrimp are found along India's east and west coasts and are caught using trawls, nets, and other fishing gear. Their management is important as some populations have declined due to overfishing. The fishery has increased production over time through intensified fishing efforts but also faces sustainability challenges.
Antigen and Antibody in fish immunology
Antigens can be proteins, polysaccharides, nucleic acids, or lipids that elicit an immune response. Antigens are recognized by B cell receptors or T cell receptors when complexed with MHC. Antigenicity refers to the ability of an antigen to bind antibodies, while immunogenicity is the ability to induce an immune response. Antibodies are Y-shaped glycoprotein molecules composed of light and heavy chains that bind to antigens with high specificity and affinity. There are five classes of antibodies (IgG, IgM, IgA, IgD, IgE) that have different structures and functions in the immune response.

Nutritional requirement of cultivable fin fish: larvae, juveniles and adults
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.
Coldwater fisheries ppt

Mullet Fish Culture
This document summarizes the culture methods for mullet fish. There are two main culture methods - monoculture and polyculture. The key steps include seed supply from wild or hatchery sources, nursery rearing for 4-6 months, on-growing using either monoculture or polyculture techniques in earthen ponds for 7-8 months, harvesting using nets, and handling and processing for fresh or chilled markets. Proper water quality maintenance, disease control, and analysis of production costs and market demand are also important considerations for mullet aquaculture.
Fishing Gear selectivity
Gear selectivity refers to a fishing gear's ability to target and capture certain species, sizes, or sexes of fish while allowing incidental bycatch to escape unharmed. Most gears like trawls selectively catch larger fish, while some gears like gill nets selectively catch fish within a certain size range. The selection curve shows the size ranges caught by a gear. A bell curve indicates the optimum size range, while a sigmoid curve shows how percentage retained increases with size. Gill nets catch fish by wedging, gilling, or tangling in meshes. Mesh size, net dimensions, hanging ratio, and environmental factors influence gill net selectivity. Proper understanding of selectivity allows sustainable fisheries that return juveniles.
Penaeus monodon breeding and hatchery management

These topic contains global scenario of aquaculture, demand consumption scenario and present status of aquaculture in India. These presentation also contain constraints, future prospects and challenges in aquaculture. Different aquaculture practices throughout the world. INTEGRATED FISH FARMING & MANAGEMENT
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
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.

INTEGRATED FISH FARMING & MANAGEMENT
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
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
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
CRAB AND LOBSTER CULTURE
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
Cage Culture of Grouper and Cobia
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
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 SEABASS CULTURE
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.
BREEDING AND SEED PRODUCTION OF CATFISH
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
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.
Supplementary-Fish-Feed
• Fish needs some extra feed
along
with
available
natural feeds in water for
their regular growth.
• This extra feed which are
provided to fish is called
supplementary feed of fish.
Rice bran
•Refined pulse and wheat roughage
•Mustard or sesame cake
•Fish-meal (fish powder)
•Blood and innards of bird or animal
•Green leaves of various vegetables
•Minerals and vitamins
•Kitchen leftovers, etc.
BIOFERTILIZERS (AZOLLA FARMING)
The term 'Biofertilizer' itself means 'Live
Fertilizer'.
contain live or latent beneficial microbes
which help to fix atmospheric nitrogen,
solubilize
and
mobilize
phosphorus,
translocate minor elements (Zinc, Copper,
etc.,) to the plants, produce plant growth

ORNAMENTAL FISH BREEDING
This document discusses ornamental fish breeding in India. It notes that India's share of the global ornamental fish trade is very small at only 0.008%, and that 95% of exports are currently based on wild collection rather than breeding. To sustain growth, it argues that the focus needs to shift to culture-based development and mass breeding of the many species that can be successfully bred in India. The document provides details on the technology, species, management practices, and financial requirements for starting an ornamental fish breeding project.
