Influence of different oil sources on growth, disease resistance, immune response and immune-related gene expression on the hybrid grouper (♀ Epinephelus fuscoguttatus × ♂ E. lanceolatu), to Vibrio parahaemolyticus challenge

The aim of this study was to investigate the effects of feeding alternative dietary oils to hybrid grouper fish (♀Epinephelus fuscoguttatus × ♂E. lanceolatu) on their growth, histological morphology of hepatocytes, disease resistance, immune response, and expression of immune-related genes. Seven experimental fish meal-based isonitrogenous and isolipidic diets were formulated containing 5% fish oil (FO; acting as controls) and various vegetable...
