Abstract: Fish poly-culture of the Indian major carps, Catla catla (catla), Labeo rohita (rohu) and Cirrhinus mrigala (mrigal) together with the Chinese grass carp (Ctenopharyngodon idella) in stagnant water bodies without aeration was carried in tribal areas of Buttaigudem Mandal, West Godavari District, Andhra Pradesh. Rainwater was harvested in small size water bodies, which were under-utilized and are being used for the storage of water for agriculture during summer season. These underutilized water bodies were converted into fish production for their livelihood of tribal farmers through income generation and nutritional security. Under tribal sub plan activities by Krishi Vigyan Kendra, Venkataramannagudem four such small water bodies in Pandugudem and Bandarlagudem villages of Buttaigudem Mandal were selected for implementation of the programme. Better management practices were followed and aimed at high yields of table size fish during this short duration of water storage. Manures like cow dung, goat dung, poultry excreta, etc., were used to produce the plankton in the ponds. The fishes were fed with the commercial pelleted protein rich feed having 24 % protein. Maximum growth and size was achieved in the grass carp followed by catla, rohu and mrigal. The production was varied from 2162 kg /acre to 2883 kg/acre and this rose to an average of 2412 kg/acre. The average gross income generated was recorded as about Rs. 2,41.200/- (Average market price of Rs. 100/- per Kg.). The duration of the culture was 10 months. This demonstration shows that the raising of fish in semi-intensive culture for growing of fish in tribal areas for their enhanced income generation and nutritional security.
