Fish Observations During Delta Smelt Experimental Releases Inferred from ARIS Sonar

This dataset includes post-processed data for underwater fish observations by using Acoustic Resolution Imaging Sonar technology in Montezuma Slough, Sacramento River, and in the Sacramento Deep Water Shipping Channel in the Sacramento-San Joaquin Delta, California, USA. This data release includes sample data associated with each video file collected, swimming behavior of groups of released cultured Delta Smelt (Hypomesus transpacificus) that is associated with all three release types, and tracking data on both released cultured Delta Smelt and ambient fish that were observed underwater using sonar technology. This data release includes data from years one to three of the Delta Smelt Experimental Releases, in water years 2022 to 2024.
