Interagency Ecological Program: San Francisco Bay Study Survey for Fish and Mobile Crustaceans 1980-2025
Listed in California Open Data
The San Francisco Bay Study (Bay Study) was established in 1980 to determine the effects of freshwater outflow on the abundance and distribution of fish and mobile crustaceans (brachyuran crabs and caridean shrimp) in the San Francisco Estuary, mainly downstream of the Sacramento-San Joaquin Delta.
Description
The Bay Study survey currently samples 52 open-water stations monthly from a research vessel with two types of trawl gear: a midwater trawl to sample pelagic fishes, and an otter trawl to sample demersal fishes, crabs, and shrimp.
Historically, the study also included plankton sampling (1980-1989) for larval fish and crustaceans. Fish collected by the otter and midwater trawl are identified to species, counted, and a representative subsample is measured. In addition, crabs from the otter trawl are identified, counted, sexed, and measured, and gelatinous zooplankton from the midwater trawl are identified and counted.

Shrimp are retained from each otter trawl sample and returned to the laboratory for processing, which includes identification, counts, sex, and length. Additional data collected at each station includes water depth, Secchi, and a water column profile of temperature and conductivity. This data publication includes fish, crab, shrimp, gelatinous zooplankton (jellies), and water quality data.
Metadata related to the plankton sampling will be included in the future when this data is published. ## About This Federated Record This CNRA Open Data Platform record is based on metadata federated from the Environmental Data Initiative (EDI) Data Portal. Its purpose is to improve the discoverability of the data package through the CNRA Open Data Platform. The EDI Data Portal is the repository of record for this data package.
