This data release includes field data for fishes sampled through mid-water trawls and otter trawl methods from Suisun Bay, California to the mouth of the Sacramento River. These data were collected in August through September, 2022; October of 2023; and in September, 2024 as a part of a multi-year study of Suisun Dredging and Fish Distribution (SDFD). This data release includes quantitative data on collected fish taxa and environmental conditions focused on habitat differences between shipping channels and shoals. Sampling was done using short duration (~15 minute) trawls alongside associated water quality sample and Acoustic Doppler Current Profiler (ADCP) data collected at variable locations, depths, times, and currents.
