Interagency Ecological Program: USFWS Delta Boat Electrofishing Survey, 2018-2021

Metadata Updated: September 26, 2025

The United States Fish and Wildlife Service's (USFWS) Delta Boat Electrofishing Survey was designed to estimate spatial and temporal trends in abundance, occupancy, capture probabilities, and related environmental drivers of fish assemblages across nearshore littoral habitats within the Sacramento-San Joaquin River Delta. The USFWS Lodi Field Office in collaboration with the United States Geological Survey developed the survey in 2018 to expand fish monitoring and inferences in nearshore habitats not monitored by long-term USFWS beach seine surveys within the San Francisco Estuary. The survey uses a robust statistical framework, including a stratified random sampling design and segmented transects that act as spatial replicates for occupancy modeling.
