Özet

Present study was conducted to provide information on the adaptation capability of salema to culture conditions and evaluate growth performance and bio-economic benefits as a potential candidate for marine aquaculture and alternative to fishing. Wild fish caught using casting nets were fed with trash fish initially until adapted to tank conditions. Thereafter fish were adapted to pellets by gradual replacement of trash feed. Dry feed adapted fish were then fed experimental diets containing four different protein levels (25, 30, 35, and 40%). Overall, salema fed lower protein diets showed better performance and bio-economic results. Broken-line analyses indicated that the optimum protein for best performance were 30.5% under the conditions applied in this study. Finally, salema might be acclimatized to culture conditions and artificial diets, however, further studies are encouraged under different water temperatures with long-term feeding and different stocking densities, artificial spawning and fry production before a conclusion on the feasibility of salema culture can be made.
