Molecular and Physiological Insights Into Handling Stress Responses in Hybrid Grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus)

Aquaculture Research, Volume 2026, Issue 1, 2026.
Handling stress is a significant challenge in intensive aquaculture, often compromising fish welfare, immunity, and overall productivity. This study investigates the skin transcriptomic responses, blood plasma enzyme activities, and histological changes in the liver, spleen, and head kidney of hybrid grouper (Epinephelus fuscoguttatus × E. lanceolatus)

Replacement of Fish Meal With Poultry Viscera Meal in Diets for Juvenile Arapaima gigas: Growth Performance, Hematological Parameters, Fillet Composition, and Gut and Liver Histology

Aquaculture Research, Volume 2026, Issue 1, 2026.
This study aimed to evaluate the effects of replacing fish meal with poultry viscera meal (PVM) in diets for juvenile Arapaima gigas, assessing growth performance, hematological parameters, fillet composition, and gut and liver histology. Five isonitrogenous (450.20 g kg−1 crude protein [PRO]) and isocaloric (20.02 MJ kg−1 gross energy) diets were ...
