Effect on Intermediary Metabolism and Digestive Parameters of the High Substitution of Fishmeal with Insect Meal in Feed.

and were tested on account of their potential to replace fish protein in feed. Two levels of replacement for , 30% and 50% (H30 and H50), and one for , 50% (T50), as well as an additional diet with a modified fatty acid fraction (H50M), were investigated in relation to juvenile growth indices, enzyme activities and gut microbiome. A T50 diet showed similar results to a control (C) diet, with no significant differences regarding morphological indices and minor differences for nutritional indices.
