FIGURE 1.

Percentage of ingested pellets, in relation to offered pellets, of rainbow trout fed agar pellets containing water alone (control) or 0.1 M L-leucine, L-valine, or L-proline. The results are shown as mean + SEM of 16 different experiments in which four fish were used per group in each tank. Different letters indicate significant differences (P < 0.05) between different groups. P-values are: C vs L < 0.001, C vs V = 0.511, C vs P = 0.012, L vs V < 0.001, L vs P = 0.005, V vs P = 0.142.
