Relative bias in catch among long-term fish monitoring surveys within the San Francisco Estuary
Brock Huntsman, Brian Mahardja, Samuel M. Bashevkin
2022, San Francisco Estuary and Watershed Science (20)
Fish monitoring gears rarely capture all available fish, an inherent bias in monitoring programs referred to as catchability. Catchability is a source of bias that can be affected by numerous aspects of gear deployment (e.g., deployment speed, mesh size, and avoidance behavior). Thus, care must be taken when multiple surveys—especially...
