Production of catfish, Chrysichthys nigrodigitatus, in brackish water ponds in Nigeria using groundnut cake as supplemental feed

Abstract A comparative study of catfish, Chrysichthys nigrodigitatus (Lacepede) production was made in brackish water ponds near Lagos Lagoon using groundnut cake as the main supplementary feed. Data obtained included food conversion values, condition factor, length-weight relationships, survival and growth. Significant differences were recorded in lengths and weights of catfish given supplemental feed and those in natural ponds. In ponds without feed, catfish had a 114.1% gain in weight, and those given supplemental feed had a 858.1% gain in weight.
