An experiment was conducted on the comparative growth performance of Clarias gariepinus larvae using Micro worms (Panagrellus redivivus) and Coppens crumbles respectively. Three thousand pieces of Clarias gariepinus larvae of 2 days old having mean weight of 4.5±0.05mg and length of 5.18±0.04mm was randomly distributed into two separate feeding trials A & B, and replicated thrice in each feeding trial. Clarias gariepinus larvae were stocked at the rate of 500 larvae per replicate in a slow flow-through system water vats measuring 0.9 x 0.45 x 0.45m3. Larvae on feeding trial (A) were fed with 0.2mm Coppens crumbles while larvae on feeding trial (B) were fed with Micro worms. The larvae were fed thrice a day base on 5% body biomass for 28 days. There is significant difference (P≤ 0.05) in the feeding trials. Larvae on feeding trial (B) had higher weight gain, feed intake, specific growth rate, protein efficiency ratio, survival rate (%) and feed conversion ratio than Larvae on feeding trial A. Therefore, Panagrellus redivivus could be recommended for the feeding of Clarias gariepinus larvae due to their better growth performance.
