Table 3 Whole-body composition of L. vannamei fed the six experimental diets containing six different levels of crude protein (25, 30, 35, 40, 45, and 50% for P25, P30, P35, P40, P45, and P50, respectively)

From: Dietary protein requirement of Pacific white shrimp Litopenaeus vannamei in three different growth stages
