Hello friend,

In India, there many research institutions and universities, where scientists are working on novel and innovative technologies, required by our fishery farmer and suitable for our climatic conditions.

The main innovative technologies, on which our scientists are working as:



Quality fish seed production:

Scientists are working on quality fish seed production to produce the fish rich in proteins and other essential micro nutrients. Using induced breeding of cultivable Carp fish the use of pituitary extract and ovaprim have been optimized fro Tarai region of India. The techniques of double breeding of culturable Carps in one breeding season has also been developed which has potential of increasing fish seed production from the same number of fish stock and available resources.



Development of Model Circulatory Hatchery:

An economy model of portable circulatory hatchery of 1 meter diameter and made up of tin has been developed. It can hold one lakh eggs at a time with more then 80% hatching success. This is least cost intensive and also require less space. This can be used and small farmers field for quality fish seed production.

Nursery Management Technique:

The technology involves pumping of filtered water with plankton populations from adjoining stock ponds to nursery ponds. This makes having three to four crops of seed feasible in single breeding season instead of usual two crops by saving the intervening period required for preparation of nursery ponds. It also improves recovery rate up to 60-70%.



Biogas slurry as fish food and fertilizer:

Substitution of 40-50% conventional supplementary feed that is oil cake and rice bran by bio-gas slurry has been found to reduce the cost of fish production considerably. With its better percentage of Nitrogen, Phosphorus and Potassium (NPK) constituents compared to cow dung it is also acts as better manure.



Lake and reservoir fisheries:

The district of Nainital (Uttrakhand) abounds in lakes in hills and reservoirs in Tarai regions. The fisheries of these lakes is however, in dire state. Fish production from these precious water bodies could be increased up to 70-80% kg per hectare per year by stocking suitable farm raised fish species. The fish production of Sat Tal , a medium altitude lake in Nanital region, Uttrakhand was increased from 2-3 to 80 kg per hectare per year by stocking Indian major Carps, under fisheries development in high altitude lakes programs. The research work showed that stocking of the reservoirs with detritophagus fishes will result in increased fish production.



Besides these there are many more innovative techniques on which our scientists are working.
