- •
Optimal dietary protein level of hybrid grouper juveniles was estimated to be 53.5% of dry matter.
- •
The optimal value of dietary P/E ratio at 53.5% dietary protein is 157 mg/kcal for hybrid grouper juveniles.
- •
Lower P/E ratios not only resulted in lower weight gain but also produced higher lipid accumulation in the abdominal cavity.
