Cost of Alternative Effluent Treatments for Catfish Production
نویسنده
چکیده
impact of effluent discharge from aquaculture facilities is a growing concern among policy makers. Since 1974, the United States Environmental Protection Agency (EPA) has regulated discharge of pollutants to waters of the United States under authority of the National Pollutant Discharge Elimination System (NPDES) permit. In some states, the NPDES permits have been applied to effluents from aquaculture facilities. These regulations may cause farmers to consider alternative production methods for either effluent removal or reduction.

Effects of sesame seed meal and bambaranut meal on growth, feed utilization and body composition of juvenile African catfish Clarias gariepinus
Plant proteins are plausible fishmeal substitutes but are deficient in some essential amino acids (EAA) like lysine and methionine. Combination of different plant proteins with complimentary EAA could be useful alternative. Bambaranut (Voandzeia subterranea) contains high amount of lysine while methionine is in sesame seed (Sesamum indicum). This experiment tested effects of combining sesame se...

An experiment was conducted to test using effluents from intensive hybrid catfish (Clarias macrocephalus × C. gariepinus) ponds as nutrient inputs for Nile tilapia (Oreochromis niloticus) culture, which would reduce effluent effects from catfish culture, gain extra fish production at low cost, and possibly make aquaculture more profitable to farmers. Three treatments were done with three replic...

Two experiments were conducted in 200-m earthen ponds at Asian Institute of Technology, Thailand, for 87 days to test the feasibility of an integrated pen-cum-pond system, which utilizes wastes from intensive culture of hybrid catfish (Clarias macrocephalus C. gariepinus) as nutrients for semi-intensive culture of Nile tilapia (Oreochromis niloticus). This integrated pen-cum-pond system enhance...
