Pertumbuhan dan efisiensi pakan ikan nila merah (Oreochromis sp.) yang dipelihara pada media bersalinitas

Abstract

The objective of this research was to know the effect of salinity on the growth and utilized of feed energy by red tilapia, Oreochromis sp. Four fishes with 4,15-4,42 g initial body weights were cultured in a 50x40x35 cm aquarium for 40 days. Fish were fed on these diets three times a day at satiation. Dietary growth rate, feed efficiency, protein and lipid retention increased with increasing salinity (p<0.05). No significant differences in feed consumption and survival rate were observed at different salinities. From this research it can be concluded that the best condition for red tilapia was salinity of 10-20°/00
