Nutrients in Wild and Farmed Fish and Shellfish

ABSTRACT Wild and cultivated channel catfish, rainbow trout, coho salmon, red swamp crayfish, white river crayfish and Eastern oysters were analyzed raw and cooked for proximate composition and ten vitamins. Cultivated catfish had 5 and salmon 2 1/2 times more fat than their wild counterparts. In all other species wild and cultivated samples had similar nutrient content. Cholesterol was independent of fat content and similar in wild and cultivated samples. Vitamin B12 in 100g met or exceeded the 1989 Recommended Dietary Allowance (RDA) for adults of 2 μg/day in all species. Other B vitamines seldom exceeded 10% of the RDA except for niacin in finfish. Vitamin A, ascorbic acid and folic acid levels were negligible.
