India is endowed with inland freshwater resources, which contribute both livelihood and
nutritional security to the rural community. These natural water bodies are biologically
sensitive and threatened by an array of anthropogenic and climatic factors. Uncertainty in
reception and availability of the water for fish culture causes inappropriate stocking of fish
seed leading to poor fish production. Availability of quality fish seed at appropriate times is
the major constraint for the development of aquaculture in these natural water bodies of
Andhra Pradesh. To address this issue, Krishi Vigyan Kendra, Amadalavalasa conducted a
demonstration on captive nursery rearing of fish seed in Jagannathanaidu tank, of Srikakulam
district of north coastal Andhra Pradesh, located at 18 0 48.037’ N, and 83 0 53.729’ E. Three
to five-day-old spawn stage fish seeds of Indian Major Carps Catla (Catla catla), Rohu
(Labeo rohita), and Mrigala (Cirrhinus mrigala) were released in a 27 m 3 water spread area
of 6X3X1.5 m sized net cage at the rate of 1, 50,000 numbers. The culture of fish seed was
carried out for 15 days up to the fry stage in net cages. It was observed 32.18 % of survival
rate and produced 48270 numbers of fry. Through this activity, the farmer could save an
amount of Rs.9394 on fish seed purchased from outside. This fry-stage fish seed was in turn
reared in rearing ponds for 1-2 months until fingerling size to stock the grow-out culture tank
immediately after reception of water. Based on the above results it is recommended that
nursery rearing of fish seed is remunerative, reduces losses during transportation, and assures
the quality of fish seed in the required quantity.
