"Striped bass (Morone saxatilis) were tagged on the Umpqua and Smith rivers (Figure 1) to estimate the numbers of bass recruited to the cornmercial fishery and to gather information on migration habits of bass in these rivers. Small numbers of striped bass were tagged in the summers of 1971 and 1972, but most were tagged in the springs of 1972 and 1973. Tagged striped bass were recaptured by the commercial and sport fisheries. White sturgeon (Acipenser transmontanus) and green sturgeon (A. medirostris) captured incidental to striped bass were also tagged." (Introduction)
