Abstract

As fish feed plays a major role in aquaculture profitability, reduction of cost determines successful productivity. This has necessitated the search for non-conventional feedstuffs that are cheap. The objective of this study is to assess the growth performance of extruded Irvingia wombolu (bitter African bush mango) peel based feed in catfish. The peel was sundried, ground into a fine mixture, the proximate analysis was carried out in the laboratory. The ground mixture was mixed with other feed ingredients at different inclusion rate of 5%, 10%, 15% and 20%, an extruder was used to produce fish feed pellets. Fingerlings were stocked ten per plastic tanks (40 litres) with a replicate for each treatment and each tank was filled with 30 litres of water (two-third of the volume of the tank) and water changed daily. Dried fish feed pellets were used in feeding fingerlings of catfish with average weight of 3.8g at 5% body weight for 8 weeks. The growth performance was analyzed to determine the weight gain, specific growth rate, food conversion ratio, survival rate of the fish and digestibility of the feed. SPSS ANOVA statistical analysis was used to analyze the results. The proximate composition of Irvingia wombolu peel was discovered to have crude protein (3.9%), crude fat (1.13%), crude fibre (12.37%), ash (4.13%) moisture (10.05%). Results obtained from the experiment showed significant difference (p
