Fisheries Online Information System - Survey of pelagic and demersal habitats within the northern California Current
공공데이터포털
The Northwest Fisheries Science Center (NWFSC) conducts a comprehensive groundfish bottom trawl survey encompassing the U.S. West Coast between the borders with Canada and Mexico (Keller et al. 2008) and water depths of 50 to 1280 meters. This survey was not designed to quantitatively sample the young-of-the-year (YOY) life history stage. Since 1996, the Zooplankton Program at the NWFSC has conducted biweekly hydrography and plankton cruises along the Newport Hydrographic line (NH-Line) across the central Oregon shelf (44.67N) (e.g., Peterson and Keister 2003, Peterson 2009). On each cruise, hydrographic measurements and zooplankton samples are collected at stations ranging from 1 to 25 miles from shore. These zooplankton cruises build on and complement a broad range of historic and ongoing oceanographic sampling focused on the NH-Line. For FY11, the NWFSC received Cooperative Research funding to conduct a seasonal fishing vessel-based survey of young-of-the-year (YOY) groundfishes along the NH-Line synoptically with the Zooplankton Labs plankton/physical oceanography sampling program. The YOY groundfish, ichthyoplnakton and zoopplankton work are, in part, operating as a cooperative survey of pelagic and demersal habitats within the northern California Current,. The database stores data from ongoing field collections made by the OSU Fisheries Oceanography Research Team in collaboration with NOAA Fisheries. Field activities include plankton tows, benthic beam trawls, water column hydrographic profiles, and in-situ video observations of fish behavior.

Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), a comprehensive information system and predictive model for Californias wildlife. The CWHR System was developed to support habitat conservation and management, land use planning, impact assessment, education, and research involving terrestrial vertebrates in California. CWHR contains information on life history, management status, geographic distribution, and habitat relationships for wildlife species known to occur regularly in California. Range maps represent the maximum, current geographic extent of each species within California. They were originally delineated at a scale of 1:5,000,000 by species-level experts and have gradually been revised at a scale of 1:1,000,000. For more information about CWHR, visit the CWHR webpage (https://www.wildlife.ca.gov/Data/CWHR). The webpage provides links to download CWHR data and user documents such as a look up table of available range maps including species code, species name, and range map revision history; a full set of CWHR GIS data; .pdf files of each range map or species life history accounts; and a User Guide.

This dataset is a subset of the Tuolumne Aquatic Resources Relational Inventory (TARRI) compiled by Brian Quelvog, California Department of Fish and Game. The database focuses on estimates of fish populations in the central Sierra Nevada counties specifically Tuolumne, Calaveras, Stanislaus, Mariposa, Mono, and Alpine counties. Information includes the number of individuals per species collected during each of two or three passes with backpack electrofisher(s), section length, section width, date, species sampled, the identifier, UTM coordinates, and (if available) photographs of the site. The species documented include rainbow and brown trout, centrachids such as bluegill and green sunfish, cyprinids such as roach and hitch, as well as other groups (eg. mosquitofish and catfish). Over seventy-five sources of information were used in making the data set including aquatic surveys by several agencies, although most of the information is contained in file reports from the California Department of Fish and Game. Collection dates range from 1979 to 2003. What each record represents Each record represents the collection, identification, and count of one species of fish during one of two or three passes with backpack electrofisher(s), the zone, water, site, UTM coordinates, date, and person or organization responsible for the survey.
