    Bioled rice bran, Moina sp., boiled tilapia flesh, fresh chub mackerel viscera and fresh pig blood were tested as feeds for raising fry of pla duk dan (Clarias batrachus). The fry, averaging 0.233 to 0.316 g, were reared in pottery water jars containing 5 l of water that was exchanged every two days. The feeds were applied at the rate of 5% of the body weight of the fry/day. At the end of the 65 day trials the best growth gains, ranging from 0.51 to 0.82 grams/fish, were attained with the Moin a, tilapia and mackerel feeds. Average weight gains with the rice bran and pig blood feeds were 0.35 and 0.38 grams/fish, respectively. Survival was relatively high in all cases, ranging from 71 to 92%. The highest net production in each trial was with mackerel feed, being the equivalent of 10.6 kg/m3 in trial No.1 and 6.5 kg/m3 in trial No.2; the corresponding values for tilapia feed were 8.1 and 6.0 kg/m3 while net production on Moina feed in trial No.1 only was 9.9 kg/m3. Reasons to account for differences in growth and production results for the same treatment, between trials, were not evident.

    Artificial Reproduction and Pond Rearing of the African Catfish Clarias Gariepinus in Sub-Saharan Africa - A Handbook 1996

    The manual is based on the practical experiences of the authors on the artificial reproduction and pond rearing of the African catfish Clarias gariepinus within FAO field projects in the Central African Republic, the Republic of the Congo, Kenya and Nigeria. The manual is divided into five major sections dealing with: 1) general biology, including natural feeding habits and reproduction; 2) artificial reproduction, including induced propagation without and through hormone injection; 3) fry nursi ng in earthen ponds, including pond preparation, fertilization, feeding and management; 4) monoculture, including feeding methods; and 5) polyculture with Tilapia. In addition, information is provided concerning the economics of different fingerling and grow-out farming practices in Africa, and concerning diseases and hybridization.
