The feeds are a fundamental element for a good part of the aquaculture production. Its impact on the operating costs of companies is considerable, so that, in a context in which the profit margin is not very high, the increase in its price can have a very negative effect. And one of the fundamental parameters that determine the evolution of feed prices is, in turn, the cost of raw materials: fishmeal and fish oils and different plant species like soy, lupin, rice, wheat, etc., but also marine by product coming from fish trimming and animal by product coming from animal industry including poultry meal, feather meal, hemoglobin, etc. To cultivate fish is necessary to elaborate sustainable fish diets. Modern aquaculture need to utilize the right ingredients for every fish species, but also ingredient that are having a low impact with the environment, containing sustainability credentials but also securing the welfare and growth of the fish. Ingredients are the source of nutrient and energy to cultivated fish and they need to be well studied and knows in to obtain health and robust fish. Therefore, this particular study is trying to create a more flexible opportunity for new ingredients with potential use in marine aquaculture, specifically for sea bass, fish species with an important commercial value in aquaculture industry in Mediterranean countries like Spain, Greece, Turkey, etc. Specifically, the study will generate important information about digestibility of the ingredient and how these are affecting the fish welfare and growth.
