As a centre of advanced learning and research in frontier areas of fisheries science, CIFE has generated commendable research outputs and commercially-viable technological packages. Some of the prominent ones among them are:
 
Hatchery and rearing technology

Keeping pace with time, CIFE has developed various scientifically backed techniques for hatching and seed production of commercially important high value fishes. Among them, important species for which hatchery technologies have been developed include Machrobrachium rosenbergi, a member of non-penaeid prawn, catla - rohu hybrid, Indian magur and Indian major carps. The modification of rearing devices for carp spawn, and an improved circular hatchery design are also outcome of the CIFE’s long experience with hatchery and seed rearing practices.

Mass scale production of Indian magur seed is one of the much acclaimed success stories from CIFE. CIFE has established and demonstrated the mass scale production of Indian magur fingerling at Raipur for the Department of Fisheries, Chhattisgarh and supplied seeds to many locations in India.

CIFE has also been successful in breeding the giant freshwater prawn in artificial sea water thereby enabling us to even think of prawn hatchery in completely inland sector.

 
Aquaculture technology for utilisation of salt- affected areas
CIFE has developed the hatchery technology for Machrobrachium rosenbergii in inland saline groundwater. This technology may have far reaching consequences in utilising million of hectares salt- affected lands in Gujarat, Rajasthan and Haryana. In addition to hatchery technology, culture technology for Mugil cephalus, Chanos chanos, Etroplus suratensis, Machrobrachium rosenbergii, and P. monodon in saline groundwater has been demonstrated.
 
Fish feed and nutrition
No hatchery or culture practice is successful without a proper understanding of feed and nutrition requirement. CIFE through its high quality research has come out with formulations and structural parameters of feed for P. monodon, M. rosenbergii juveniles and for aquarium fishes. In addition probiotic agents and live food organisms have been evaluated for their suitability as food/feed supplements for various kinds of cultured organisms.
 
Fish for human nutrition
Low cost and sometimes even trash fishes can be suitably modified to acceptable form fetching better prices for them. With proper scientific understanding of the properties that stimulate the taste buds, the fish meat from pink perch, dhoma have been converted to various ready to eat products. The vegetable proteins that are usually low in Lysine content has been suitably mixed with high lysine containing fish meat to make products. Conventional products like papad, pickle have been prepared scientifically. Capital intensive extruded products have also been developed. Flavour extraction technique from shrimp waste has been standardized. This product can be utilized for preparation of imitation products.
 
Post-harvest biotechnology
Fermented fishes are widely consumed in north-eastern and eastern India. The complicated fermentation process have been understood in details and using biotechnological methods it is now possible for us to reduce the fermentation time for both ‘lona ilish’ and ‘seedal’ by 50%.
 
Fish health management

PCR based technique has been successfully used for research on white spot syndrome virus and bacterial pathogens. A biological product SLC urinum has shown great promise in combating white spot disease in farmed shrimps. Apart from diagnosis and treatment of diseases, CIFE has made commendable progress in having a holistic approach in health management.

Use of probiotics for better health and use of nitrogenous bacterial fertilizer in culture systems are studied and recommended for better fish health and better environmental health.
 
Fish resource management

Anthropogenic effects on resources at primary and secondary productivity level have been studied. Changes in bacterial communities, biochemical parameters, heavy metal concentrations and microscopic organisms reveal that the pollution along Mumbai coast stretch upto 5 km from the shore.

CIFE has been successful in assessing the finfish and shellfish resources of North-west sector of Indian EEZ. A database for marine fisheries of Maharashtra has also been developed.

In inland sector, potential of cage culture has been studied in details. The cage culture of fry to fingerlings of commercially important fishes in open waters has been developed to augment the natural stock in open waters. Successful trials of cages that can be dismantled and transported showed potential of being used in several reservoirs of India.

 
Bioactive substances from marine organisms
Extracts and exudates from several organisms were screened for bioactive properties. Five species of jellyfishes, one species of octopus, cone snails, three species of catfishes and two species of sciaenid fishes were identified as potential sources of bioactive substances. Biotoxins from marine cnidarians and conids evaluated for their therapeutic potential. Crude and partially purified fractions of mucus toxin from Arius dussumieri and Osteogeneiosus militaris exhibited toxicity to mice, edematic activity and hemolytic on chicken erythrocytes.
 
Genetic improvement of fish
Population genetics studies reveal that stocks of P. monodon from east and west coast are not genetically different. There are significant differences in economic characters between the groups. These differences provide scope for up-gradation and genetic selection of the animal. Methods to cryopreserve germplasm of several commercially important fishes have been developed at CIFE.
 
Globalisation and Fisheries Trade
Studies on the impact of trade liberalization and WTO agreements on exports of fish products have shown that t hough significant growth is evident in India’s export quantity and value, the unit value realization is declining in recent years; p ost liberalisation period has brought greater degree of instability in global seafood market. The global market has become a buyer’s market with premium on quality. Competitors like Thailand and Vietnam were becoming more competitive than India
