Abstract

A comparative management and economic evaluation of catfish (Clarias gariepinus) farming using graded levels of mango endocarp meal and Coppens have been carried out. This was done by evaluating the effect of feeding graded levels of mango endocarp meal (Mangifera indica Linn) inclusion in replacement of maize in the diet of C. gariepinus fingerlings for growth performance and feed utilization in comparison with the conventional foreign fish feed, Coppens. Six (6) experimental diets were used for the research. The diets were graded levels of the Bende variety mango endocarp meal which were used in place of maize at 0%, 25%, 50%, 75%, 100%. These graded levels of the Mango endocarp meal and the Coppens were fed to C. gariepinus fingerlings for six (6) months beginning from November 2016 to May 2017.  This was done to compare the fish production enhancement of the feeds as a management approach to C. gariepinus production, the possibility of creating jobs for the teeming unemployed youth, creation of wealth, and economic enhancement of the fish farmers. The data obtained were subjected to a one-way Analysis of variance (ANOVA) and the means for the various parameters were compared for significant differences at a 95% confidence limit. The results showed that fish fed with Diet 6 (Coppens) recorded the highest average weight gain (312.7g), specific growth rate (2.23), Feed Conversion Ratio (1.98), the protein efficiency ratio (1.18), while diet Diet 5 (100% mango endocarp meal) recorded the least average weight gain (19.21g), specific growth rate (0.66), feed conversion ratio (4.45), the protein efficiency ratio (0.34). Results showed that mango endocarp meal should not be more than 25% in the diet of C. gariepinus fingerlings to enable the farmers to achieve optimum fish growth and production.
