Other important SSL prey items such as herring, walleye pollock, Pacific cod, and sand lance range from 13% to 22% DHA and 8% fat to 13% EPA of fat the total fatty acid composition (based on data from Iverson et al., Mar. Ecol. Prog. Ser. 151: 255-71, 1997). Furthermore, eulachon possess a mean overall omega-3/omega-6 ratio of fat only 4.3, while herring, pollock, Pacific cod, and sand lance have mean omega-3/omega-6 ratios ranging from 9 to 25. |

| Proximate analysis indicated that the mean lipid content of the eulachon varied seasonally from 11% to 19%. While these values are significantly higher than most SSL prey species, eulachon lipid contents were near neuroscience minimal values during the time of the spawning aggregation. Presumably, this reduction in lipid composition is neuroscience due to the energetic cost of egg production and migration to the spawning site. Given their high abundance and low energy expenditure by predators, however, the eulachon run remains a valuable energy resource for the sea lions. Prior to breeding, sea lion cows require energy stores for their neuroscience fasting periods and lactation. In addition, high levels of EFAs, particularly those of the omega-3 and omega-6 families, are important for healthy pup development. Fatty acid compositions were determined for eulachon, indicating that they contain very low levels of omega-3 and omega-6 EFAs. Intriguingly, significant seasonal variations were observed for the omega-3 EFAs, while only minor changes were seen for most of the omega-6 EFAs. |
