ABSTRACT The northern Humboldt Current System (nHCS) has high environmental variability that impacts key demographic and community‐scale processes. Understanding the role and ecological implications of these interannual or long‐term events is crucial in describing the dynamics of the nHCS community. Using catch data from pelagic assessment surveys from

Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]
The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark,

Based on the findings of this study, the best protein quality related to N. japonicus with an EAA index of 75.92. P. indicus has the best lipid quality due to the high ratio of ω‐3/ω‐6 (1.68) and PI (7.02). The abundant trace elements in all five fish species, K, Ca, Fe, and Zn, as well as these fish species, have good nutritional quality based on Na/K
