Use of Non-Native Columbia River American Shad (Alosa sapidissima) as an Alternative Fishmeal Source for Juvenile Sablefish (Anoplopoma fimbria)

In this study, we investigated the use of American shad (Alosa sapidissima) as an alternative fish protein/fish oil ingredient for aquaculture feeds. American shad is a non-native species that resides in marine and inland waters of the Pacific Northwest. The population of shad has increased since their introduction to the West Coast in the late 19th century, and is currently considered the largest anadromous fish population in the Columbia River.
