Induced Spawning of Pangasius sutchi with Pituitary Extract

Document format: pdf

Publisher: Network of Aquaculture Centres in Asia-Pacific

Creation date: March 2002

The main species of Pangasid catfishes recently adopted for culture with Indian Major Carps are Yellowtail catfish (Pangasius pangasius) and Sutchi catfish (Pangasius sutchi). These fishes were introduced into the farming system of Bengal from Thailand through Bangladesh in 1994-95. Though carnivorous at an early stage, the fish are compatible with Indian Major Carps from five days onwards and can grow to 3 kg/year on a balanced diet. These fish have already established their importance as profitable species in aquafarming of Bengal. As a result of its remarkable growth rate (almost one kg in 90 days), now there is much enthusiasm among the fish-breeders and farmers of Bengal for its artificial spawning and culture. The demand for its seed is increasing by day. In view of the increasing demand for Pangasius sutchi seed we tested techniques for induced spawning and larval rearing of this fish.
