Hydrolysed wheat gluten as part of a diet based on animal and plant proteins supports good growth performance of Asian seabass (Lates calcarifer), without impairing intestinal morphology or microbiota

Fishmeal used to be the major source of proteins, especially for marine fish and salmonids. Nevertheless, its inclusion in diets has been reduced. Some commercial fish feeds may contain less than 10% fishmeal, largely replaced by a mix of animal and plant proteins. Our manuscript demonstrates that hydrolysed wheat gluten may be used to formulate high quality low fishmeal diets.
