摘要：Feeding trial was conducted to assess survival and growth rate of Clarias gariepinus and Heteroclarias (hybrid of Clarias gariepinus and Heterobranchus longifilis ) larvae (3-day old) fed on live and frozen Daphnids. Live and Frozen daphnia were used as starter diet at 50 Daphnids per larvae per feeding time for each of the species for fourteen days to assess their performance. The response to the feed and the species were compared. Heteroclarias and Clarias gariepinus fed live Daphnids performed better in terms of growth rate than those fed Frozen daphnids, though, no significant difference (p<0.05) statistically. Clarias gariepinus and Heteroclarias fed Frozen had greater survival than those fed live Daphnids. Heteroclarias fed live and Frozen Daphnids performed better in growth and survival than Clarias gariepinus . Therefore, Live Daphnids is recommended for larvae though Frozen Daphnids can be used as supplement and Heteroclarias is recommended for aqua culturists for better growth and survival.
