The study is specifically concerned with the effect of fish waste as fed component on the growth performance of fingerlings. Treatments evaluated in the study were: Treatment I-Commercial fishmeal+rice bran (control), treatment II -commercial fish meal+fish waste+rice bran and treatment III-fish waste +rice bran. The study was laid out in a Completely Randomized Design (CRD) with three replication. The feeding experiment was conducted for the duration of 90 days. Results showed that Treatments II and III obtained slightly higher average gain in length of 4.17 cm and 4.13 cm, respectively. Treatment I had the lower gain in length of 4.03 cm. However, statistical analysis revealed no significant difference in gain in weight of the fish among treatments. Higher gain in weight was obtained in Treatment II with a mean value of 1.58 g, followed by treatment III with a mean value of 1.56 g. Treatment I obtained slightly lower gain in weight of 1.48 g. Analysis of variance on the gain in weight however, revealed no significant difference among the treatments. Highest survival rate was attained in Treatment III at 100%, followed by Treatment I with 95.56%. Survival rates of treatment II were 93.33%. Statistical analysis on fish survival rates revealed no significant differences among treatment means. Better feed conversion ratios were attained in treatment I and II both with a value of 2.0. Treatment II had FCR value of 2.1. Analysis of variance revealed no significant differences on treatments.
