Aquaculture Nutrition, Volume 2026, Issue 1, 2026.Despite the increasing use of plant‐based energy ingredients in aquaculture, few studies have evaluated the digestibility of practical diets formulated with these ingredients in an integrated manner with the metabolic responses, intestinal health, and productive performance of fish. This limits the understanding of their nutritional effects. This study
