Studies on the nutrition of marine flatfish. The effect of different dietary fatty acids on the growth and fatty acid composition of turbot ( Scophthalmus maximus )
1. Five groups of juvenile turbot ( Scophthalmus maximus ) which had been given a diet free of fat for 12 weeks were given diets in which the lipid component (g/kg) was: oleic acid alone 50, oleic acid 40+linoleic acid 10, oleic acid 40+linolenic acid 10, oleic acid 40+arachidonic acid 10 or oleic a...
