The Billfish Angler Survey provides estimates of billfish angling activities in the Pacific and Indian Oceans. This collection of recreational billfish catch and effort has occurred annually since 1969 and provides an index of fishing success in many Pacific billfish destinations. Catch per unit of effort (CPUE) is measured in catch of billfish per angler fishing day. This measure of angler success, tracked over time, can indicate changes in stock size caused by over fishing, changing environmental conditions, or local economic and political events. Only a small proportion of the data are from anglers in the Indian Ocean.
The North Pacific and South Pacific Albacore Troll and Pole-and-line Fisheries project contains landings, logbooks, and size composition data from U.S.A. troll and pole-and-line vessels fishing in the North and South Pacific, from 1952 and 1987, respectively, to the present.
The project’s objective is to document movement patterns and survival rates of Chinook salmon, steelhead, green sturgeon, and other fish from several sources in the Central Valley of California. Juvenile salmonids from hatcheries or wild caught are implanted with small acoustic transmitters and the location of the fish are recorded on receivers that are placed throughout the watershed from Redding to the Golden Gate. Over 70 receiver locations with over 150 receivers monitor the movement of these fish. These receivers record the date, time, and unique identification number of transmitters that pass within listening range of the receivers. The first acoustic tagging studies began in 2006 and continue today.
This data set contains vessel logbook and landings data from harpoon vessels that fish within 200 miles of the California coast, from 1974 to present. The harpoon fishery targets swordfish and occasionally sharks. The fishery is managed by California Department of Fish and Wildlife (CDFW). The data are owned by CDFW and managed jointly by CDFW and SWFSC.
This dataset contains detections of acoustic tagged fish from two general locations: Golden Gate (east and west line) and Pt. Reyes. Several Vemco 69khz acoustic receivers were deployed at each of these general locations. The Golden Gate receivers were deployed beginning in April 2005 while the Pt Reyes receivers were deployed beginning in July 2008. The tagged fish in the dataset include all fish tagged by NOAA Santa Cruz and some green sturgeon tagged by NOAA in the Columbia River and Willapa Bay. Only a subset of these tagged fish were detected at the Golden Gate and Pt. Reyes. There are detections of many more fish that are not in the list of tagged fish in this dataset.
An archive of multi-frequency and multi-beam echosounder data (Simrad .raw format), collected as part of SWFSC-FRD surveys of the U.S. west coast between San Diego, CA and Vancouver Island, BC. The archive contains echo power and inerferometric-phase-angle data that describe acoustic backscatter from marine organisms ranging in size from zooplankton to fish.
The Fisheries Ecology Division (FED, https://swfsc.noaa.gov/GroundfishAnalysis/) of the Southwest Fisheries Science Center (SWFSC) has conducted a midwater trawl survey off central California since 1983 with the primary goal of developing pre-recruit indices for young-of-the-year (YOY) rockfish (Sebastes spp.). The survey also samples numerous other components of the epipelagic micronekton, including other YOY groundfish (such as Pacific hake, Merluccius productus, and sanddab, Citharichthys spp ), coastal pelagic fishes (such as Pacific sardine, Sardinops sagax, and northern anchovy, Engraulis mordax) and other forage species. Additional details regarding the survey methods and results are described in Ralston et al. (2015) and Sakuma et al.
