Optimal amounts of coconut oil in diets improve the growth, antioxidant capacity and lipid metabolism of large yellow croaker (Larimichthys crocea)

The purpose of this study was to investigate the effect of different dietary coconut oil (CO) levels on growth, antioxidant capacity and lipid metabolism of juvenile large yellow croaker ( Larimichthys crocea ). Five iso-nitrogen (45% crude protein) and iso-lipid (13% crude lipid) experimental diets were prepared by replacing 0% (the control), 25%, 50%, 75% and 100% fish oil with coconut oil. The results showed that dietary CO had no significant effect on survival rate (SR, P > 0.05). However, the specific growth rate was increased significantly when compared with the control group when fish were fed the diet with 50% CO ( P
