Abstract

In the present study, the effects of different dietary protein levels on salema porgy, Sarpa salpa (Linnaeus, 1758) juveniles were investigated. Six iso-caloric (20 kJ/g diet) diets with increasing protein levels (30, 37, 40, 47, 50, and 57%) were formulated. Each test diet was randomly fed to triplicate groups of 13 juvenile fish (initial mean weight 19.28±0.13 g) to satiety over 90 days. Growth performance and feed utilization were best with low dietary protein levels of 30 and 37%, but decreased with diets containing protein levels over 40%. Ammonia nitrogen excretion showed an increasing trend as dietary protein levels gradually increased, whereas retention rates of ammonia nitrogen per intake were highest in the low protein groups of 30 or 37%. The analyses of specific growth rate by broken-line regression indicated that the optimal dietary level of protein for salema porgy juvenile were 33.6% under the conditions applied in this study. As a result, S. salpa demonstrated better growth with low protein diets, showing that this marine fish could be a promising candidate for a sustainable and environment friendly aquaculture industry.
