Abstract

Dietary effects of lipid source, lipid level and temperature on growth of glass eel (Anguilla anguilla).

Abstract

Glass eels maintained at 25° or 27°C had significantly higher body weight than those maintained at 23°. The average weight increase of eels fed on poultry oil (PO), 5 and 10% in the diet, and maintained at 25 and 27° was significantly higher than that of eels fed on soyabean oil (SBO). Eels kept at 25 and 27° and given PO had a higher lipid content than had eels fed on SBO. The percentage of C18:1 fatty acid in body lipids was greater with PO than with SBO in the diet and also greater with 10% than with 5% PO. Values for C16:0 and 16:1 acids were similarly affected but C18:2 acid was higher with SBO than with PO in the diet.
