Abstract

Commercial (Multifeed) diets were fed to Clarias gariepinus fry earlier weaned from decapsulated Artemia and dried mixed-cultured zooplankton at (3% and 5%) feeding rates each for 21 days, to assess fry survival and growth on the two feeding rate. Dietary treatments were in triplicate, in a completely randomized design. Fry were randomly distributed into 12 aerated, 30litres plastic tanks at a stocking rate of 30 fry per tank.  The best percent survival (40.00±31.80) which was not statistically (P>0.05) significant from other treatments was in the fry fed commercial feed at 3% feeding rate, which were weaned on zooplankton. Specific growth rate was not significantly (P>0.05) different but higher (6.37±0.91) in the fry fed commercial feed at 5% feeding rate, earlier fed Artemia at 5% feeding rate. FCR, GFCE, and FE of fry fed commercial feed at 3% feeding rate, which were earlier fed zooplankton, were the best with no significant (P>0.05) differences among the four treatments. The study revealed that the fry earlier fed decapsulated Artemia and those fed dried mixed cultured freshwater zooplankton could be weaned on commercial feed at 3% and 5% feeding rates, with no significant (P<0.05) difference on the fry growth, survival and feed conversion.
