Effect of dietary lipids on growth, tissue composition and metabolism of the oyster (Crassostrea virginica).
Hatchery reared oysters (Crassostrea virginica) were fed six different diets for 30 weeks. The diets contained cod liver oil (CLO), corn oil (CO), corn oil and cod liver oil (1:2) (CO + CLO), hyrogenated coconut oil (HCO), ethyl esters of cod liver oil fatty acids (SF) or cod liver oil ethyl esters supplemented with cholesterol (CH). Data on growth and tissue composition imply that oysters have an essential fatty acid (EFA) requirement for both linolenic or omega 3 and linoleic or omega 6 series fatty acids, with the former playing a more significant role. The feeding study supported by a 14C-acetate metabolism experiment suggests that these oysters were unable to synthesize sterols and excessively high dietary sterol (1% of the dry weight of the diet) inhibited growth.
