The California Recreational Fisheries Survey (CRFS) mission is to collect fishery-dependent data on California's marine recreational fisheries, and to accurately estimate catch and effort in a time frame and on a scale that meets management needs. CRFS collects the data necessary to estimate catch and effort for California's diverse recreational finfish fisheries which range from the California-Mexico border to the California-Oregon border extending over 1,100 miles of coast and is surveyed at over 400 sampling sites. Annually, CRFS conducts over 7,000 sampling assignments and contacts over 68,000 fishing parties. High sampling rates produce confidence in estimates with a 20 percent sample rate of private boat anglers during salmon or groundfish seasons. CRFS collects the data to produce the estimates for all sport-caught finfish.
The Environmental Monitoring Program (EMP) began in 1975 to conduct baseline and compliance monitoring of water quality, phytoplankton, zooplankton, and benthic invertebrates in the San Francisco Bay-Delta estuary. This monitoring program was designed to track the impact of water diversions to the State Water Project (SWP) and Central Valley Project (CVP) on the Bay-Delta. In the decades since, EMP scientists have monitored these constituents at fixed and floating stations throughout the estuary and ensured compliance with state and federal mandates such as Water Right Decision 1641 (D-1641). In the years and decades since its inception, EMP has become one of the cornerstones for scientists' and managers' understanding of the pace and pattern of change in this critical ecosystem. By sampling water quality and biological communities concurrently, EMP has created a dataset that is uniquely useful in better understanding causal connections between physical, biological, and biogeochemical processes.
The Environmental Monitoring Program (EMP) has conducted the Zooplankton Study since 1972 to better assess trends in the lower trophic food web in the San Francisco Bay-Delta estuary. The study also detects and monitors zooplankton recently introduced to the estuary and determines their effects on native species. Under the auspices of the Interagency Ecological Program for the San Francisco Estuary and mandated by Water Right Decision D-1641, the EMP Zooplankton Study is part of the Environmental Monitoring Program and is conducted by the California Department of Fish and Game (CDFW), California Department of Water Resources (DWR), and the United States Bureau of Reclamation (USBR).
