Practical Diets Formulated With Different Plant‐Based Energy Ingredients Modulate Nutrient Utilization and Gut Morphology in Tambaqui (Colossoma macropomum)

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

Comparative Evaluation of Feeding Tiger Puffer (Takifugu rubripes) With Trash Fish and Formulated Feeds on Growth Performance, Flesh Quality, Antioxidant, and Immunity Capacity

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
This study evaluated the effects of replacing trash fish (TF) with formulated feeds in tiger puffer (Takifugu rubripes) on the growth performance, liver and serum biochemical indices, flesh quality, and metabolomics. Fish (39.6 ± 0.2 g) were fed TF, commercial feed (CF), and self‐formulated feed (SF) for 8 weeks. Results indicated that CF and SF groups
