CON, H20, H40 and H60 represent 0%, 20%, 40% and 60% inclusion of H. illucens larva meal, respectively, BIO is a commercial diet (BioMar Inicio, Brande, Denmark). SD, standard deviation, SEM, standard error of the mean; K, condition factor; HSI, hepatosomatic index; SSI, splenosomatic index; VSI, visceromatic index; PFI, perivisceral fat index; SL, splenic lipidosis; NF, not found. Different letters within a row indicate significant difference (p ≤ 0.05). * Statistical analysis did not include BIO. No statistical analysis was performed for SL, as some diet groups did not show lipidosis.
