    California Recreational Fisheries Survey [CRFS]

    Lead California Department of Fish and Wildlife [CDFW]
    Description 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.

    Central Valley Chinook Adult Escapement Monitoring Project

    Lead California Department of Fish and Wildlife [CDFW]
    Description The Central Valley Chinook Salmon In-river Escapement Monitoring Plan is a science-based collaborative approach to improve monitoring of adult Chinook salmon returning from the ocean to spawn in CV streams (escapement) and harvested in freshwater. Accurate estimates of escapement are critical to sound management of ocean and inland harvest and monitoring the recovery of listed stocks. A result of requests from fisheries resource managers, the development of this plan was funded in 2007 by the CALFED Ecosystem Restoration Program. The comprehensive monitoring plan includes a spatially and temporally balanced sampling protocol that when implemented will allow for statistically defensible estimates of population status. The plan incorporates an adaptive management strategy, and recommends a standardized database structure, as well as standardized reporting techniques.
