The Environment Agency undertakes fisheries monitoring work on rivers, lakes and transitional and coastal waters (TraC).

This dataset contains site and survey information, the numbers and species of fish caught, fish lengths, weights and ages (where available), for all the freshwater fish surveys carried out across England from 1975 onwards.

Notes: - These survey data are stored in an archive more commonly known as the NFPD (National Fish Populations Database). - This dataset contains Freshwater fish surveys only. - Third party data held on the NFPD are excluded from the dataset. - Some historic surveys (particularly in Anglian Central) have incorrect survey lengths and survey widths. These can be identified by a survey length of 1 and a survey width that is equal to the area. The survey areas are correct. This is due to the migration of old historic data from previous databases into the NFPD. - Approved for Access under AfA347.

This dataset contains the accumulated stream survey data collected to identify climate impacts to fish communities and assess stream restoration as a potential climate-change mitigation action across the Great Plains and High Desert of Wyoming and Montana (2021-2024). We also provide data of incidental observations of amphibians, reptiles, crayfishes, and mussels seen while conducting fisheries work, as well as structured surveys for amphibians and crayfishes. Habitat data for many sites is also provided.

The data is reported in Catch Per Unit Angler (CPUA) which is a simple calculation of the number of fish caught divided by the number of anglers targeting the fishery type within a particular 1' block in a given period. CRFS Catch records for all caught species were aggregated into 5-year bins from 2004-2024 as well as the entire period. All catch of these species were summed and attributed to the blocks (1' x 1' area) which were recorded during the survey interview. If multiple blocks were recorded, then the catch data was divided across all blocks indicated. Catch data is further divided into 'kept' and 'released' fish which is used to calculate a CPUA for only kept fish and a CPUA for both kept and released fish. The total number of anglers targeting any species in each block was calculated for each time frame. An angler represents a single person fishing in a block on a single day. The data is limited to blocks that had 3 or more reported fishing trips over the entire time period. Effort under the 'All' trip type is an aggregation of all anglers surveyed. This includes anglers from specific trip types such as highly migratory, salmon, bottomfish, coastal migratory, inshore, other anadromous, invertebrates and anything. Raw data from 2004 - 2015 was extracted from the Pacific States Marine Fisheries Commission (PSMFC) legacy RecFIN database. Data from 2016 - 2024 was extracted from the CDFW's CRFS data system. The data is divided into reported catch (includes reported kept, reported released alive, and reported released dead), observed kept catch, effort and location tables. Attributes: Block Box: 1' grid where the data was reported. Catch: The species or the name of the species group whose individual catch records were aggregated. Trip Type: Trip type category that includes the primary target species for the angler that was aggregated. This layer is an aggregation of all angler effort. All_04_09: CPUA for both kept and released catch for 2004-2009. All_10_15: CPUA for both kept and released catch for 2010-2015. All_16_20: CPUA for both kept and released catch for 2016-2020. All_21_24: CPUA for both kept and released catch for 2021-2024. Kept_04_09: CPUA for only kept catch for 2004-2009. Kept_10_15: CPUA for only kept catch for 2010-2015. Kept_16_20: CPUA for only kept catch for 2016-2020. Kept_21_24: CPUA for only kept catch for 2021-2024. CPUA_All: CPUA for both kept and released catch for the entire 2004-2024 period. CPUA_Kept: CPUA for only kept catch for the entire 2004-2024 period. This field is used as the source of the symbology for this layer. Gray blocks represent where effort occurred, but no catch was reported. Samples: The number of individual survey samples that reported fishing in block for the entire period.

Data provided in this collection were gathered around Puerto Rico as part of NCCOS-led missions in collaboration with partners at U.S. Fish and Wildlife Service, University of Puerto Rico Department of Marine Sciences, HJR Reefscaping, and University of the Virgin Islands.

In 2014 the Belt Transect method was used to conduct fish surveys in Puerto Rico as part of the ongoing National Coral Reef Monitoring Program (NCRMP). The Belt Transect method collects and reports information on fish species composition, density, size, abundance and derived metrics (e.g., species richness, diversity). Surveys were concurrent with and along the same transect as the Line Point-Intercept (LPI) benthic survey. Starting in 2016 fish data were collected using the stationary point count method. This method collects and reports information on fish species composition, density, size structure, abundance and derived metrics (e.g., species richness, diversity).

Total numbers of individual fish identified during the Cefas Young Fish Survey (YFS) which ran from 1981 to 2010. The survey deployed a light 2-meter beam trawl to survey inshore locations for small / young fish around the British Isles, predominantly along the south and east coasts. Total numbers of fish (identified to species or if not to the highest taxonomic level) were recorded at each station, and were measured in the majority of cases. The surveys were primarily undertaken to evaluate the abundance of juvenile sole and plaice, as well as providing further information on the abundance of other species of fish. Alongside the main 'Young Fish Survey Data 1981 to 2010' data table are three further data tables marked as 'YFS_DWC' which give the same data in EventCore format and a readme file which describes historic versions of metadata which this record has replaced.

PLEASE NOTE: This dataset has been superseded by the Transitional & coastal water fish surveys (NFPD) and is now retired. These products are Approved for Access under AfA347. The National Fish Populations Database (NFPD) holds information collected from fisheries monitoring work on rivers, lakes and transitional and coastal waters (TraC). This monitoring work is undertaken by the Environment Agency and by third parties. All the relevant data associated with NFPD TraC fish surveys, such as survey information, site information, the numbers and species of fish caught, fish lengths, weights and ages (where available), can be obtained from these relational datasets. The data is provided as a set of relational data tables because there is just too much data to include all relevant information in all tables. A basic understanding of fisheries science and relational databases is assumed. Available datasets/tables: • TraC Fish Counts for all species for all Areas and all Years • Breakdown of TraC fish count data types (individually measured, banded measured and bulk counted fish) • Individually measured TraC fish records • Banded measured TraC fish records • Bulk counted TraC fish records The tables can be related to each other using any one of the unique identifiers - survey_id, survey_species_id, species_id and species_run_id. However, the TraC Fish count dataset has no dependence on the other tables and can therefore also be used in isolation. Third party data and surveys not flagged as ‘Completed’ are excluded.

Data collected includes the following: Densities of yellow eel, juvenile salmon and juvenile trout at 40-50 sites, fish (per m2) and lengths of individual fish. Data collected from the Burrishoole catchment rivers and lakes within Furnace Newport Co. Mayo. Data surveys have taken place annually since 1959. Data surveys have involved surveys of salmon and trout stocks taking place in the rivers and main lakes of the catchment. Electrofishing, with 3 fishing depletions, are used for salmonids in the streams and fine mesh beach seines are used in the lakes. Data has been collected to ascertain knowledge on the abundance of key target species in the Burrishoole catchment. Data originally collected by the Guinness Estate and more recently by the Marine Institute Newport facility team. Data is 100% complete for each year since 1959. .hidden { display: none }

The fish dataset presents results from High Mountain Lakes (HML), SLIP (Sierra Lakes Inventory), and Redwood Sciences Laboratory (RSL) project fishery surveys. Both projects collected data on high elevation waters in the Sierra Nevada and mountains of Northern California using a standard protocol. Surveys of fish, amphibians, habitat, and stream barriers were done at each site between late-May and October. Fish surveys were mainly done using standardized 6 panel monofilament gill nets, set for 8-12 hours. Fish species, length, weight, and sex are recorded for each individual. As many sites were only visited once, the data presented represent a "snapshot" view of the fish population in a particular lake. SLIP surveys were done in the John Muir Wilderness by Roland Knapps crews in 1995-1996. HML surveys were done in Regions 2, 4 and 6 by CA DFW crews between 2001 and 2010. CDFW crews did not survey within National Park boundaries and no SLIP data from National Parks is included here. RSL surveys were conducted between 2001 and 2006, and additional surveys in Northern California ranges were conducted by HML crews in 2008 and 2010. As of May 2010, approximately 85% of the total mapped waters in the High Mountain Lakes range have been surveyed. It should be noted that the High Mountain Lakes expanded in 2007 to include water bodies in cascades frog range. "Baseline" survey types indicate a full survey was done at the site, including amphibian, fish, habitat characteristics, tributary characteristics, and photos. Generally this survey type occurs during the initial visit to a particular site. "Monitoring" surveys are repeat surveys of fish or amphibian populations at a site, and generally do not include habitat or stream barrier data. WHAT EACH RECORD REPRESENTS: This dataset represents field data collected in high elevation Sierra Nevada and Northern California lakes, meadows, streams, and springs. If no fish were observed, each record represents a single fish survey. If

These data include goals, objectives, and performance measures from management plans and monitoring surveys related to fisheries management in the St. Clair-Detroit River System and the Western Basin of Lake Erie. Researchers extracted these data from existing management plans identified from on-line grey literature searches and discussions with collaborators and regional fisheries management personnel

The West Coast Vancouver Island (WCVI) synoptic bottom trawl survey was first conducted in 2004, and has been repeated every second year to 2018. The 2020 survey was postponed to 2021 due to 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 Haida Gwaii (WCHG) 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 the Canadian Coast Guard research vessel W.E. Ricker. In years when the W.E. Ricker has not been available, the Hecate Strait and West Coast Vancouver Island surveys have taken place on chartered industry vessels. The data provided include information about the annual survey trips and fishing events (tows/sets) that are part of this survey series, including the vessel name, dates, times, spatial coverage, gear details, and effort information. Catch information (total weight in kg or counts of individual specimens) is included 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). Some catches were subsampled and biological data were collected from individual fish specimens, including length, sex, and weight information. Where age structures were collected and processed, fish ages have been included. Relative abundance indices are provided for species that have been captured in every survey of the time series. The coefficient of variation and bootstrapped 95% confidence intervals are provided for each index. The groundfish data synopsis report (Anderson et al. 2019) provides an explanation of how the relative biomass indices are derived.

the cgfs campaign is part of a historical series of fishing surveys that began in 1988 (cgfs eastern part, conducted on the r/v gwen drez) and was extended to cover the entire english channel regularly from 2018 (on r/v thalassa). oinly data for the eastern channel is presented. for data from the western channel please see "wcgfs".for both surveys, the main objective is to collect basic data for estimating the state of resources through direct assessment of stock abundance and distribution, along with biological sampling of the catches. taking place every year between mid-september and mid-october, it contributes to the european project for the contractualization of basic fishery data collection (dcf). the campaign also allows for sampling and a better understanding of the entire ecosystem, aligning with the implementation of an ecosystem-based approach to fisheries at the community level. the cgfs also provides data for numerous national and international research projects. the collected and validated data are transmitted at the end of each campaign to national databases (sih, harmonie, coriolis) and the european database (datras), enabling their use by different working groups and ensuring public access to this data. finally, the cgfs data contributes to the baseline assessment of the impact of numerous marine aggregates extraction projects (through a multi-year convention signed between the ministry of ecology, sustainable development and spatial planning, ifremer, and brgm) planned or underway in the eastern english channel.
