The optimal stocking density and the survival rate of African Catfish Heteroclarias Hybrid under laboratory condition was conducted. 180 fingerlings of Heteroclarias Hybrids of four weeks old were bought from Markudi, Benue State and were randomly chosen after acclimatization for two weeks. They were each counted 4, 8, 16 and 32 with two replicates each in to 16litres bawls filled up to 10litres level in treatments DI, D2, D3 and D4 respectively. Their various weights, total and standard lengths, were measured using 30 cm meter rule for their lengths and 200 (g) digital Weighing Scales Camry (model T1432682) of 5000g (5kg) after every week. The mean percentage weight, total length and standard length were calculated and subjected to one way ANOVA analysis to determine their level of significance. The result indicated that D2 (8 fingerlings) had the best stocking density with ICTL (39.75), SR (100), SGR (0.489), RGR (24.10) and PI (10.71) which were significantly (P<0.05) different from other densities (treatments).
