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) 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).
