The three fleets consist of set gillnet vessels targeting halibut and angel sharks, small-mesh drift gillnet vessels targeting white sea bass and yellowtail and large-mesh drift gillnet vessels targeting swordfish and thresher sharks. In addition, observer data are available from the large-mesh drift gillnet fleet. The data are owned by CDFW and managed jointly by CDFW and SWFSC. The data collected from California-based drift gillnet vessels are used by CDFW, NMFS, and the Pacific Fisheries Management Council to monitor and manage the drift gillnet fishery, to collect information used in stock assessments of species caught in this fishery, to monitor the bycatch of protected species, and to fulfill the reporting obligations of the Regional Fisheries Management Organizations (RFMOs). underDevelopment Gu, Yuhong (858) 546-7053 (858) 546-7003 8901 La Jolla Shores Dr La Jolla CA 92037 USA Yuhong.Gu@noaa.gov M-F 8:00 - 16:30 Contact via email pointOfContact Gu, Yuhong (858) 546-7053 (858) 546-7003 8901 La Jolla Shores Dr La Jolla CA 92037 USA Yuhong.Gu@noaa.gov M-F 8:00 - 16:30 custodian annually drift gillnet gillnet landings length composition logbook observer swordfish thresher shark theme north pacific place DOC/NOAA/NMFS/SWFSC > Southwest Fisheries Science Center, National Marine Fisheries Service, NOAA.

Coverage should be 100%. Comparisons of logbooks and landings show that some logbook data may be missing in some years Length Composition data sampling coverage seems low but has not been evaluated. Accuracy Landings data are submitted by buyers and accuracy is very high. Logbook data are completed by vessel captains and can be suspect.

Typical Gillnets are made of monofilament, multimonofilament, or multifilament nylon constructed of single, double, or triple netting/paneling of varying mesh sizes, depending on their use and target species. A specific mesh size will catch a target species of a limited size range, allowing this gear type to be very selective. Charter vessels-small boats various vessels ranging in size (20-40 ft length) chartered for cetacean surveys when a NOAA small boat is not available.
