CWPA CPS Nearshore Cooperative Research Survey Video
In cooperation with the California Department of Fish and Wildlife and Southwest Fisheries Science Center, CWPA is developing sampling methods to assess sardine and anchovy in nearshore waters not surveyed in NOAA acoustic trawl surveys. Both sardine and anchovy are abundant in California’s coastal waters inshore of current NOAA acoustic trawl surveys; in fact, approximately 70 percent of California coastal pelagic species landings are harvested in waters not surveyed in federal stock assessments. The sharp decline reported for both sardine and anchovy in recent years is belied by our nearshore surveys, and fishermen’s observations, that find increasing populations of both species. Accurate biomass estimates and stock assessments for CPS will benefit sustainable harvest policies, fishermen and seafood processors who produce these species, as well as our fishing communities and seafood consumers.
Our aerial survey samples CPS schools using aerial spotter pilots with plane and aerial camera system to fly transects near shore and photo-document schools, coupled with qualified purse seine vessels chartered to capture a subset of the schools identified while the pilot photographs the “point sets.”
