Abstract
The plasma nonesterified fatty acids (NEFA) of five species of temperate zone marine teleost fishes (Northwestern Atlantic), one Arctic marine teleost (Eastern Canadian Arctic), and four species of marine elasmobranchs (Northwestern Atlantic) are reported. Four fatty acids, 16:0, 18:1n9, 20:5n3 and 22:6n3, comprised 70 to 83% of total NEFA in the plasma of all temperate teleost species examined. With the sole exception of 18:1, these differed from the predominant fatty acids, 14:1, 16:1, 18:1 and 20:5n3, in the Arctic species. The predominant fatty acids in elasmobranch NEFA were 16:0, 22:6n3 and 18:1n9 in all species but saturated fatty acids (14:0, 16:0 and 18:0) accounted for 40% of all NEFA in all elasmobranchs examined. Monoenes represented a greater, and polyenes a smaller, percentage of the fatty acids in the Arctic sculpin compared to the temperate sculpin. Fatty acids of the n3 series were lower in the plasma of the Arctic sculpin compared to the temperate sculpin. Comparisons with published values for freshwater fish using the same method indicate the n3:n6 ratio is higher in the marine teleost fishes. Ratios of n3:n6 fatty acids ranged from 1.80 to 7.94 for the elasmobranchs and were on average lower than those for the marine teleosts. Total levels of NEFA for the elasmobranchs were between 193 and 399 nmol ml-1, lower than the values reported here for teleosts but within the range reported by others for some teleost fishes.
