Table 3 Growth performance of rainbow trout during the complete growth trial: A) direct effects of the HP, LP and HPR diets; B) effects of the HP, LP and HPR histories. Data represent means ± SD (n = 9 samples per group). Values with different superscripts in the same row are significantly different (P < 0.05)

From: Higher glycolytic capacities in muscle of carnivorous rainbow trout juveniles after high dietary carbohydrate stimulus at first feeding
