The College has the mandate to develop scientifically proven technologies that can be transferred to the fish farmers of not only the State but whole of the North-India. The increased emphasis is given to frontier areas of carp culture, seed production, water quality management, fish health management, conservation of fish diversity and fisheries resource management. The significant technologies developed so far are as follows-
Significant Technology Developed
Research work
1. Induced breeding and quality seed production of carps
To ensure availability of quality seeds of cultivable carps throughout the year, the induced breeding technology using crude pituitary extract, ovaprim, ovatide, Wova- FH, Gonopro- FH and Ovarim has been developed for the Tarai region of Uttarakhand. Catla, Rohu, Mrigal, Grass carp and Silver carp are being successfully bred and about 3.0 crore spawn is produced every year manipulating environmental factors and brood stock diet. The multiple breeding of carps in Tarai conditions has also been done.
2. Development and optimization of broodstock management practices for quality gamete production for extended period
The broodstock of different fishes collected from different sources viz. reservoir and pond of fish farmers were raised in oxygenated waters (approximately 8.0 mg/l DO) by providing highly proteinacious diet (35% protein diet with 3400 K cal/ kg gross energy having 39% soybean oil cake, 20% groundnut oil cake, 40% rice bran and 1% growth promoters). The brooders collected from different sources were kept and reared in separate ponds. The water of the broodstock ponds was replaced (10- 25%) regularly. Under these conditions, the brooders of exotic carps viz. common carp matured in January while silver and grass carps matured in March and could bred up to September. The Indian Major Carps also experienced maturity by early April in place of June. Breeding trials between reservoir and pond fishes were made and hatching, survival and growth were found to be better in these trials.
Prototype Technology Developed
1. Organic Farming Technologies
Organic production technology has been developed for most of the crops which are being grown under Tarai as well as hilly areas. Under Tarai conditions organic package of practices have been developed for Basmati rice based cropping systems. Basmati rice grain yield during five years of experimentation showed a increasing trend though slight increase in initial 3 year and a drastic increase in fourth and fifth year in 100% organic mode (52.0% more over initial) and this observed cumulative yields of basmati rice over years under organic mode of nutrient management may be attributed to the build up of organic matter, accumulation of nutrients over years and improvement in physico-chemical properties of soil.
Organic mode of cultivation recorded on an average highest net return after three years of conversion period and up to three years it was highest in inorganic mode of cultivation. Among the cropping systems, highest net return and B: C ratio was recorded with basmati rice-vegetable pea system followed by basmati rice- lentil system in all the modes of nutrient management during all the years.
2. Propagation of Haldu (Adina cordifolia)
Propagation technology reported for the first time on rooting in Adina cordifolia using macro propagation technique using mono nodal leafy softwood cuttings prepared from epicormic shoots using 6000 ppm IBA. The technology is helpful in cloning, domestication and mass multiplication of the species. This technique is useful in overcoming the problem of poor seed germination in the species which hinders the nursery production.
3. Propagation techniques for multiplication of bamboos
Propagation techniques for multiplication of bamboos in sand without use of mist chamber has been developed which can increase success for bamboo rooting and can produce more number of roots. In addition macroproliferation technique with use of fertilizer was standardized which can give higher number of plants as compared to standard technique.
