Respond of Concrete pond Raised Clarias Gariepinus Fed Diet Containing Different Inclusion Level of Cow Tripe Epithelial Waste

Abstract
The study examined the effect of Cow Tripe Epithelial Waste (CTEW) on the growth performance, nutrient utilisation and survival of advanced fry Clara’s gariepinus raised in ten homestead tanks (3m x 1.5m x 0.006m) for ten weeks. Each tank was-stocked with 100 advanced fry with initial average weight of 0.68 +- 0.55g. The diets were isonitrogenous 40% crude protein and iso-caloric (3.47 +- 1.24Kcal/g). The fish were fed equivalent of 5% of their body weight twice daily. The weights of feed were adjusted after bimonthly weighing. The water parameters were monitored at the commencement and weekly subsequently. The design of the experiment was completely randomized.

The results show that percentage survival, Gross Efficiency Food Conversion (GEFCR) and weight gain were best in the fish fed diet with 25% CTEW replacement. The growth utilisation (GEFCR) parameter evaluated was higher in fish fed the diet containing 25% CTEW replacement than those obtained in the control. The Food Conversion Ratio (FCR) of the advanced fry fed the control and diets 1, 2 and 4 were not significantly different (p < 0.05). However, the percentage Specific Growth Rate (SGR) improved with increasing CTEW inclusion. It implies that the CTEW protein could qualitatively replace fishmeal in the diets of Clara’s gariepinus advanced fry raised in homestead ponds. This is therefore recommended for inclusion in the diets of C. gariepinus  for faster growth and better management.
