Table 4 Fatty acids (% of total FAC ± SD) of diets; “sat” = saturated fatty acids; “unsat” = unsaturated fatty acids; “PUFA” = poly unsaturated fatty acids; a = t-test identified a significant difference (P < 0.05) between freshwater (Rutilus rutilus, Chironomidae larvae, and Gammarus pulex) and marine diets (Pellets, Clupea harengus, Mysis spec., and Euphausia superba)
