| Abstract | The cultivation of hybrid catfish at high stocking densities within cage environments is considered for its potential to enhance production efficiency. This study, employing a completely randomized design with four treatments and three replications, was conducted to assess the impact of varying stocking densities on growth parameters and survival rates. The treatment (Trt) groups were established based on different stocking densities, defined as the number of fish/m3 of cage. These groups included Trt1 with 5 fish/m3, Trt2 with 10 fish/m3, Trt3 with 15 fish/m3, and Trt4 with 20 fish/m3. Measurements of specific growth rates and survival rates were analyzed using analysis of variance to determine the effects of stocking densities. The ANOVA results indicated that stocking density significantly influenced both growth rates in specific weight and survival rates. Employing the Duncan multiple range test, it was revealed that Trt1, with the lowest density, exhibited the highest specific growth rate at 615.6 ± 2.8 %/ day. Conversely, the lowest growth rate of 577.1 ± 84.0 %/day was observed in Trt4, which had the highest density. Additionally, the highest survival rate was recorded in Trt1 at 96.3 %, while the lowest was observed in Trt4 at 63.5%. These results demonstrate that lower stocking densities are associated with improved growth and higher survival rates in hybrid catfish, emphasizing the importance of maintaining optimal densities to enhance health and growth efficiency. |
