Effects of formulated diet with different protein levels on growth, survival and body composition of juvenile sea bass

| description | A 40days feeding experiment was conducted with juvenile fish (mean weight 2.05±0.95g)
to know the effect of different protein levels on growth, survival and body composition of
sea bass (Lates calcarifer) juvenile. One control diet and three practical diets were
formulated to contain increasing levels of protein (35, 45 and 55%) and fed to satiation,
twice daily to triplicate groups of fish. The sea bass juveniles were distributed into groups
of 17 fish in a 70 1 fibre glass tank. Fish fed the control diet showed the highest weight
gain and specific growth rate. Those fed the diet with 41.7 and 51.9% protein showed
similar specific growth rate. Fish given diets containing 35% protein showed the poorest
growth. Survival was highest in fish fed control diet (100%). Fish given the diet
containing 35% protein had the highest body crude protein content and the highest ash
and water content. The control diet containing 41.7% primarily animal origin protein was
found to be optimum for juvenile sea bass under the experimental conditions used in the
study. Based on this study, it is suggested that the digestibility of the major ingredients
and the diets to be determined in future study. The feed additives should be included in
the diets and high quality locally available ingredients should be used. |
