The aim of the study is to identify components that can promote sustained appetite in Sea bass. Exchanging raw materials in a fish feed, even at a given basic proximate composition, requires good knowledge on their safety, as well as their nutritional and technical quality for each target fish species. Marine hydrolysates contain high levels of appetite stimulating components for fish, such as Glutamic acid, Alanine, Glycine, Proline, Leucine and betain, which induce short term increase of feed intake. Increased feed attractability, appetite and feed intake in very low FM diets is not translated to fish body weight increase in a consequent and predictable way, and it is important to understand the relations between nutrient levels, feed intake rate and fish metabolism and performance.
