Composition of Marine and Freshwater Finfish and Shellfish Species and Their Products

Storebakken and Austreng (1987) reported that feed and ration level affected the composition of farmed Atlantic salmon. Larger-sized fish tend to deposit more fat in the muscle. Fish caught in the summer and fall tend to be higher in fat than those caught in the winter and spring. However, this is variable and depends on feeding rates, environmental conditions, degree of satiation, and species.
