These datasets contain information on contracted fishing trips for an exploratory analysis of the feasibility of a fishery-independent bottomfish survey in Guam. Fishing occurred in 2012 and 2014 on Galvez bank using similar research-fishing practices to the exploratory fishing surveys done in the Main Hawaiian Islands. The data contain information on trip, catch, and effort. The trip specific data contains information on fisher and vessel, observer (person who entered the data), the port trip started in, start time and day and end time and day of trip, the fishing area, and species targeted. The effort data contains information on fishing set up including the number of hooks, species targeted, rigging type, bait used, drift and anchor usage, and time spent fishing; as well as environmental information including wave height, depth, current and wind speed. The catch data contains vessel identification, location, date, the species caught and their length, and whether gonads or the head were saved for reproductive and age measurments.

Contains information collected such as: lengths, weights, sex, quantity, species, etc. from various bottomfish and pelagic species during frequent visits to the United Fishing Agency Fish Auction in Honolulu, Hawaii.

Accurate and precise stock assessments are predicated on accurate and precise estimates of life history parameters, abundance, and catch across the range of the stock. In its continued efforts to improve the data used in stock assessments, the NOAA Pacific islands Fisheries Science Center (PIFSC) implemented a Bottomfish Fishery-Independent Survey in Hawaii (BFISH) in 2016. The BFISH survey utilizes two gear types, Cooperative Research hook-and-line fishing operations (CRF) and the Modular Optical Underwater Survey System (MOUSS). Survey sampling is conducted annually, typically in the fall, surrounding the Main Hawaiian Islands (MHI), in accordance with a stratified-random sampling design. Under this design, the waters surrounding the MHI are gridded at 500 meter resolution. Each grid is given attributes of depth, slope, and seafloor hardness. Depth categories are Shallow (75-200 meters), Medium (200-300 meters) and Deep (300-400 meters). Slope categories are Low slope (0-10 degrees) and High (10-90 degrees). Seafloor categories are Hardbottom and Softbottom. Annual survey data are processed to produce relative and absolute abundance and biomass estimates for the Stock Assessment for the Main Hawaiian Islands Deep 7 Bottomfish Complex. This dataset contains information from BotCam deployments conducted during the 2011-2015 methods comparison study, which led to the operation BFISH survey.

Tagging records of fish tagged and released were collected during NOAA R/V Townsend Cromwell cruises between 1977 and 1994. Date, location, depth, type of gear, species, species length and tag number were recorded on the collection sheet.

These data represent a cost-earnings study of the Main Hawaiian Islands bottomfish fishery for the 2010 operating year. Data collected include fisher classification, vessel characteristics, levels of investment, trip-level expenditures, fishing behavior, market participation, social aspects of the fishery, and demographics. Additionally, attitudes and perceptions towards fisheries management agencies and current and future management tools are described.

Fishing operations that focus on targeting bottomfish (mostly juvenile opakapaka) that are independent of a larger research vessel, i.e. the Oscar Elton Sette.

During May-August 2004, face-to-face interviews with owners and/or captains of all NWHI bottomfish vessels were conducted to collect primary information on costs of fishing operations in 2003. Information on physical characteristics of the vessels, motivation of fishermen, and other topics was also collected. Follow-up interviews were conducted in September 2004 and March-April 2005 to collect data missed during the first interviews. M. Pan and A. Griesemer conducted the project.

These datasets contains information on fishing trips for deep7 bottomfish in the main Hawaiian Islands by contracted fishermen from March 2015 to November 2015 around Oahu, Maui, and the Big Island. Detailed information exists at the trip and station (fishing event) level. The trip specific data contains information on fisher and vessel, the port trip started in, start time and end time of trip, the dates fishing occurred over, and the species and size targeted. Information on depths fished, wave heights and wind speeds are also provided. The station specific data contains information on fishing set up including the number of hooks, species targeted, rigging type, bait used, and time fishing started and ended, and reason for ending. It also contained information on the environment including location, wave height, current, wind. The catch data contains vessel identification; station information; the date fishing took place; the time by reel that fishing started and ended; the species caught and their length and status; and the bait used.

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
