Abstract (EN): This study was undertaken to test the growth parameters and the body composition of eel fingerlings (1.7 g) fed isoproteic and isocaloric diets with different percentages (10, 15 and 20%) of protein from fish silage. The incorporation of silage in the diet resulted in an increase in the specific growth rate, the food conversion efficiency and the protein efficiency ratio, when compared to a control population fed only a fish and meat meal, as protein source, during a 4-month period. No differences were seen in the effectiveness of the diets incorporating different percentages of fish silage. The increase in growth rate and the presence of greater amounts of lipids in the carcasses of eels receiving silage are partially due to greater food ingestion, owing probably to a different texture of the ration or the possible presence of food attractants. The pattern of amino acids did not differ much between diets, and the essential amino acids were always present in a sufficient amount. Hence the better food conversion efficiency and protein efficiency ratio (PER) of eels on the diets containing silage probably result from the good quality of the fatty acids present in the silage (great percentage of the ¿-3 series) and possibly on the greater amount of sodium present. © 1989.
