Catfish fry, Growth Rate, nile tilapia fry, stocking density ratio
This study aims to determine the optimal stocking density ratio in the polyculture system of catfish and nile tilapia fish. This study is conducted experimentally using the Completely Randomized Design with the differences in the treatment of stocking density ratio, each repeated five times. The treatments of the stocking density ratio of both the catfish and the nile tilapia include: A (75 :75 fry/m2), B (100:50 fry/m2, and C (125:25 fry/m2). The observed parameters are growth rate, survival rate and Food Conversion Ratio. The result of this study shows that the stocking density ratio significantly affects the growth rate and survival rate of the catfish and nile tilapia fry, while the feed conversion does not seem to affect them as much. The stocking density ratio that indicates the highest chance of growth rate and survival rate is 75 fry/m2 for the catfish fry and 75 fry/m2 for the nile tilapia fry.
