Estimating Juvenile Chinook Salmon (Oncorhynchus tshawytscha) Abundance from Beach Seine Data Collected in the Sacramento–San Joaquin Delta and San Francisco Bay, California.

摘要

Resource managers rely on abundance or density metrics derived from beach seine surveys to make vital decisions that affect fish population dynamics and assemblage structure. However, abundance and density metrics may be biased by imperfect capture and lack of geographic closure during sampling. Currently, there is considerable uncertainty about the capture efficiency of juvenile Chinook salmon (Oncorhynchus tshawytscha) by beach seines.
