Publication Date : 19/04/2016
Fisheries play an important role in providing livelihood option to the rural poor and also supporting Indian economy. The inland fisheries successes depend on the two critical factors the seed and the feed. The seed production systems of Indian Major Carps IMC were already standardized by central and state Govt. Research institutes. Chinese hatchery standardized for Chinese carps were also adopted for IMC. Since 1960 commercial scale of seed production of IMC is by the private hatcheries. But recently the seed quality is not up to the mark and it is deteriorating drastically. As a result, seed farms and grow out culture systems are affected with serious disease problems mostly with parasitic and bacterial diseases. It is mainly due to the inbreeding depression of stock. The present study was conducted from stretch of Kadiyam to Vetlapalem (along Samalkota irrigation canal). Fish farmers who are having nursery farms (spawn) reported that, they were facing often with parasitic and bacterial diseases. On other hand local hatcheries (within the State) are not providing healthy spawn and also brood stock is not having genetic vigour as a result of inbreeding. Further local hatcheries are inadequate to supply spawn of grass carps and big head sufficiently. As a result a fish seed farmer always depends on the West Bengal traders for supply of seed of bighead and grass carp. The present paper has been focus on the importance and urgent necessity of brood stock development to reduce inbreeding depression and increasing genetic vigour.
