Résumé
This study evaluated the effect of different experimental diets on the growth of Penaeus monodon cultured at different salinities. We used four diets in this experiment, such as diet-1 (F1), diet-2 (F2), diet-3 (F3) and diet-4 (F4). All the diets were fed to P. monodon juveniles cultured at salinities of 5 ppt (S5), 10 ppt (S10), 15 ppt (S15), and 20 ppt (S20) for a 45-day tank trial. In this study, the feed’s fishmeal protein was replaced with concentrated protein as an alternative approach to aquaculture sustainability. There was no interaction effect and no main effects of feed and salinity on the growth of P. monodon. Feed and salinity had an interaction effect, and salinity had a main effect on the survival of P. monodon. Overall, survival was higher in the tanks with higher salinity, such as 15 ppt and 20 ppt. There was also a higher survival at salinity 10 ppt where shrimps were fed with F1 (83.33±3.33%) and F2 (86.67±8.82%). Estimated marginal survival also indicated that survival tends to be raised with increased salinity. There was an environmental fluctuation during this study. Hence, this data might not indicate the general features of growth and survival of P. monodon.
