To conserve the California Current Ecosystem foodweb, it is important to understand mid-trophic level forage species. Top forage species in this system include Northern anchovy, Pacific sardine and Pacific herring, which are all commercially exploited. They are also influenced by climate, multiple species interactions, and predation. These forage species support predators ranging from seabirds to sea lions, cetaceans to salmon.
