Similarly, in this study, weight gain and specific growth rate (SGR) of fish fed L130 and L150 lipid diets were significantly lower than the values obtained for the L50 lipid diet group, which may indicate a protein sparing effect of dietary lipids (Shapawi et al., 2014). The feed conversion rate (FCR) of fish fed the L130 lipid diet was significantly higher than that of fish fed the L50 lipid diet, suggesting that juvenile Nibea albiflora could utilize dietary lipid effectively up to a certain level ( Kikuchi et al., 2009)
