Abstract
The study on culture of sea bass (Lates calcarifer, Bloch 1790) was carried out to evaluate the potential of culturing sea bass in hapa-in-pond environment. The study made used of Completely Randomized Design (CRD) with four treatments at three replicates each randomly distributed using 12 units of 2.0m x 1.0m x 1.2m net cages. Results indicated that different stocking densities did not significantly affect the weight gain and survival over the ninety days culture period. Analysis of covariance (ANCOVA) for weight gain and feed given as covariate were determined. Results showed that growth of sea bass with respect to the feed given greatly affects its growth and survival rate. From the technical perspective, results showed that at lower stocking densities, higher weight gain can be realized, lower feed competition expected and more manageable to culture not to mention that it is also a high value species. Similar studies should be done at an on-farm level to assess the economics of sea bass farming on a commercial scale. It is also recommended that alternative source of feeds for the species and the practice of grading of the stocks to prevent cannibalism be explored.
