Cooperative Research Diet Data
공공데이터포털
The data described here include prey item identifications and specifications from dissected stomachs of bigeye tuna, mahi mahi, and swordfish. These data were gathered around the North Pacific from Oct 2022 thru Sep 2023 and are still being processed. These data are part of NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD), Pelagic Research Program (PRP). These stomachs were collected by the crew of two longline fishing vessels and prey data were recorded by employees in the labs at PIFSC.
NOAA/PIFSC Towed Diver Survey Centroids: Main Hawaiian Islands
공공데이터포털
Within the depth limits of safe, no-decompression SCUBA diving (generally to 90 feet depth), NOAA-certified Pacific Islands Fisheries Science Center (PIFSC) divers conduct towed diver surveys (TDS) as a method of assessing relatively large areas of reef habitat. This method involves towing two divers (one collecting fish data, the other collecting benthic data) behind a small surface craft that is moving at a velocity of 1-2 mph. Although the driver of the surface craft attempts to follow a depth contour, the divers also actively maneuver the "towboards" they are holding onto so as to maintain a relatively constant elevation above the surface of the reef. Towed-diver surveys are typically 50 min long and cover about 2-3 km of habitat. This map layer shows the centroid location of towed diver surveys conducted throughout the main Hawaiian Islands between the years 2005-2010.
California Collaborative Fisheries Research Program
공공데이터포털
From 2007-2016, CA Collaborative Fisheries Research Program (CCFRP) scientists and fishermen have conducted hook-and-line surveys within three Central Coast State Marine Reserves (Point Lobos, Piedras Blancas (2008 only), and Point Buchon, SMRs) and a State Marine Conservation Area (Año Nuevo, SMCA), along with nearby reference sites (Figure 1). The Año Nuevo, Point Lobos, Piedras Blancas, and Point Buchon MPAs encompass areas of 10.2 mi2, 5.4 mi2, 10.4 mi2, and 6.7 mi2 respectively. Reference sites were based on the criteria that they shared similar size, habitat, and oceanographic conditions with the nearby MPAs. Within the boundaries of each MPA and reference site, 500 m x 500 m grid cells were created and used to randomly select sampling locations. The grid cells were positioned in nearshore rocky habitats, in water less than 40 meters deep (to limit fishing mortality from barotrauma), in areas that had been identified by fishermen as having suitable habitat for nearshore fishes. A total of 22 grid cells in Año Nuevo, 17 cells in Point Lobos, 57 cells in Piedras Blancas, and 22 cells in Point Buchon were generated (Figure 2). On a given survey day, four of these cells were selected at random and sampled. In 2008 and 2009, surveys were also completed in (then) proposed North Central Coast SMRs (Point Reyes, and North and Southeast Farallon Islands) and near Bolinas/ Duxbury Reef. These surveys utilized the CCFRP hook-and-line survey protocols with the exception that sampling was not completed within 500m x 500m grid cells. These trips provided an opportunity to evaluate the areas in order to locate optimal fishing areas and create grid cells for future surveys. Duxbury Reef, an open area, will serve as a project reference area because this area has been surveyed since 2005.
West Coast Haida Gwaii Synoptic Bottom Trawl Survey
공공데이터포털
Catch, effort, location (latitude, longitude), relative abundance indices, and associated biological data from groundfish multi-species bottom trawl surveys in West Coast Haida Gwaii. Introduction The West Coast Haida Gwaii (WCHG) synoptic bottom trawl survey was first conducted annually from 2006 to 2008 and has since been repeated every second year on even numbered years. The survey was not impacted by the COVID-19 pandemic. This survey is one of a set of long-term and coordinated surveys that together cover the continental shelf and upper slope of most of the British Columbia coast. The other surveys are the Queen Charlotte Sound (QCS) survey, the Hecate Strait (HS) survey, the West Coast Vancouver Island (WCVI) survey, and the Strait of Georgia (SOG) survey. The objectives of these surveys are to provide fishery independent abundance indices of all demersal fish species available to bottom trawling and to collect biological samples of selected species. The survey follows a random depth-stratified design and the sampling units are 2 km by 2 km blocks. The synoptic bottom trawl surveys are conducted by Fisheries and Oceans Canada (DFO) in collaboration with the Canadian Groundfish Research and Conservation Society (CGRCS), a non-profit society composed of participants in the British Columbia commercial groundfish trawl fishery. The Queen Charlotte Sound and West Coast Haida Gwaii surveys are conducted under collaborative agreements, with the CGRCS providing chartered commercial fishing vessels and field technicians, while DFO provides in-kind contributions for running the surveys including personnel and equipment. The Hecate Strait, West Coast Vancouver Island, and Strait of Georgia surveys are conducted by DFO and have typically taken place on a Canadian Coast Guard research vessel. Until 2016 this vessel was the CCGS W.E. Ricker. From 2021 onwards, this vessel was the CCGS Sir John Franklin. In years when a coast guard vessel has not been available, the Hecate Strait, West Coast Vancouver Island, and Strait of Georgia surveys have taken place on chartered industry vessels. Data from these surveys are also presented in the groundfish data synopsis report (Anderson et al. 2019). Effort This table contains information about the survey trips and fishing events (trawl tows/sets) that are part of this survey series. Trip-level information includes the year the survey took place, a unique trip identifier, the vessel that conducted the survey, and the trip start and end dates (the dates the vessel was away from the dock conducting the survey). Set-level information includes the date, time, location, and depth that fishing took place, as well as information that can be used to calculate fishing effort (duration) and swept area. All successful fishing events are included, regardless of what was caught. Catch This table contains the catch information from successful fishing events. Catches are identified to species or to the lowest taxonomic level possible. Most catches are weighed, but some are too small (“trace” amounts) or too large (e.g. very large Big Skate). The unique trip identifier and set number are included so that catches can be related to the fishing event information (including capture location). Biology This table contains the available biological data for catches which were sampled. Data may include any or all of length, sex, weight, age. Different length types are measured depending on the species. Age structures are collected when possible for species where validated aging methods exist and are archived until required for an assessment; therefore, all existing structures have not been aged at this time. The unique trip identifier and set number are included so that samples can be related to the fishing event and catch information. Biomass This table contains relative biomass indices of species that have been captured in every survey of the time series. The coefficient of variation and bootstrapped 95% confidence
Fishing Community Profile: Commonwealth of the Northern Mariana Islands (2017)

To enable fisheries managers to comply with National Standard 8 (NS8), NMFS social scientists around the nation are preparing fishing community profiles that present the features and characteristics of such communities. PIFSC has published or is developing four such profiles: one each for Hawaii, Guam, the Commonwealth of the Northern Mariana Islands, and American Samoa.
The Nature Conservancy (TNC) Hawaii Marine Program

The Nature Conservancy (TNC) is an international, non-profit conservation organization that works to protect ecologically important lands and waters for nature and people around the world. In Hawaii, TNC has worked with partners and members for 30 years to protect more than one million acres of critical natural lands. The TNC Hawaii Marine Program was launched in 2001 to restore and protect the near-shore coral reefs and marine resources surrounding Hawaii. With the help of local communities and conservation partners, TNC monitors the health and abundance of Hawaii's marine resources to identify major threats and develop strategies for protection. This map shows general areas in Hawaii where TNC has focused its marine monitoring efforts. For more information, please see: http://www.nature.org/en-us/about-us/where-we-work/united-states/hawaii/
