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.

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 freshwater 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: • Freshwater Fish Counts for all species for all Areas and all Years • Freshwater Salmonid Age Band (0+, >0+, age unknown) Counts for all Areas and Years • Freshwater Salmonid Age Band (0+, 1+, >1+, age unknown) Counts for all Areas and Years • Breakdown of freshwater fish count data types (individually measured, banded measured and bulk counted fish) • Individually measured freshwater fish records • Banded measured freshwater fish records • Bulk counted freshwater 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 Freshwater Fish Counts and the Salmonid Age Band datasets have 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. For more information about the available datasets/tables, please see the Dataset Documentation.

The Environment Agency's Freshwater fish surveys database has been interrogated to extract the year of the most recent survey for each survey site. The survey site points have then been matched to a CaBA catchment based on their location and symbolised according to the decade in which the most recent survey took place. The layer can be used to identify locations where freshwater fish surveys have not taken place for many years.This layer is based on data downloaded via the from the bulk download page on the Environment Agency’s Fish and Ecology Data Explorer in February 2022.The full Freshwater fish surveys database can be found on the Environment Agency's Ecology & Fish Data Explorer.

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

Freshwater fish are used as an indicator of stock status, water and habitat quality, artificial obstacles to migration and river flow requirements due to specific life-cycle requirements. This dataset is made up of the species count and length values from the freshwater river fish surveys conducted across Wales by Natural Resources Wales and former Environment Agency Wales. These surveys are conducted as part of on-going monitoring of fish in their natural environment for legislative requirements and to meet business drivers.

Protected species and invasive species records collected through Environment Agency survey, including from; BIOSYS database - invertebrate, plant and algal monitoring from marine and freshwater, the National Fish Population Database - fish monitoring, and ad-hoc records from surveys at local offices. Currently not including records for fresh water pearl mussel. Please help us to improve our species records by reporting any errors you find within this dataset to marina.flamank@environment-agency.gov.uk The invasive records are a subset of those we collect, ones with greatest impact to our work. In future we hope to include all invasive species records we collect.

This dataset mainly includes the survey of the basins, rivers, sampling points, dates, species, methods of use, and quantities of fish. The dataset is provided by the River Situation Survey Database Management System of the Water Resources Agency's Water Resources Planning and Experimental Institute, integrating the river situation data completed by the Water Resources Agency over the years. It serves as a unified management and inquiry website for river situation survey data. It is hoped to be used as reference data for river water resources management, ecological environment maintenance, and environmental improvement planning for river region structures. The key content of this dataset lies in the species, locations, and time of fish, allowing users to further analyze the spatiotemporal distribution of species. According to the operational points of the river situation survey, the survey should be carried out for at least one year, with a minimum of once per quarter, and the survey frequency should try to avoid using adjacent months as data for two seasons. The survey time should grasp the spawning period, migration period, and activity period of each fish species.

[This dataset is embargoed until August 31, 2025]. This dataset contains monthly/annual time series of species-specific abundances and covariates for 137 targeted larval/juvenile fish surveys at sites in a range of English lowland rivers. Larval/juvenile fish data come from two different sources: The Environment Agency’s (EA) National Fish Population Database (NFPD) between 1974 and 2017 and a dataset created by the University of Hull (UoH) between 1984 and 2017 inclusive. Biological data consists of density estimates of each fish species from each survey (per metre squared) and also the average length of specified species at the end of their first year of growth. Covariate data include habitat quality indicator (River Habitat Survey), climatic variables (Gulf Stream and North Atlantic Oscillation indices), land-use change, river hydrology, water temperature, effluent dilution factor and concentrations of chemical determinands. This dataset was created as larvae and juveniles may be particularly useful indicators and respond differently than older fish to environmental stressors. The work was supported by the Natural Environment Research Council (Grant NE/S000100/2). Full details about this dataset can be found at https://doi.org/10.5285/c904c5f0-7f21-4759-a7d4-c262da230b53

This dataset contains a time series of species-specific fish abundances and covariates for 1180 fish sites in English rivers. Sites with at least ten annual fish surveys in the Environment Agency’s (EA) National Fish Population Database (NFPD) between 1975 and 2017 inclusive were selected. Covariate data include habitat quality indicators (River Habitat Survey and HABSCORE outputs), climatic variables (Gulf Stream and North Atlantic Oscillation indices), land-use change, river hydrology, water temperature, effluent dilution factor and concentrations of chemical determinands. The work was supported by the Natural Environment Research Council (Grant NE/S000100/2). Full details about this dataset can be found at https://doi.org/10.5285/b0afb78e-a0cb-4762-9220-659211ae3a5e

This data release includes the results of state agency led electrofishing surveys conducted in lotic habitats in six states in the Northeastern U.S.: Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and Rhode Island. The following state agencies collected the electrofishing data: Massachusetts Division of Fisheries & Wildlife, Vermont Department of Fish and Wildlife, Vermont Department of Environmental Conservation, Maine Department of Inland Fisheries & Wildlife, Rhode Island Department of Environmental Management, Connecticut Department of Energy and Environmental Protection, and New Hampshire Department of Fish and Game. The survey results are consolidated to a Hydrologic Unit Code (HUC)12 scale and includes surveys from November 1949 through December 2021 with most surveys occurring between 1985 and 2021. Fifty-three species and 24,553 surveys are represented in these data.

In October 2013 and July 2014, Eastern IFCA undertook surveys in the estuary of the River Deben, Suffolk. The surveys were aimed at assessing and quantifying the estuarine fish population. A Water Framework Directive compatible beach seine net, deployed from a RIB and hand hauled onto the beach, was used during the surveys in 2013 and 2014. This method is the Environment Agency standard, and therefore allows comparison with EA surveys conducted in adjacent estuaries.

Marine fish are used as an indicator of stock status, water and habitat quality. This dataset is made up of the species count and length values from the fish surveys conducted across Wales marine environment by Natural Resources Wales and former Environment Agency Wales. These surveys are conducted as part of on-going monitoring of fish in their natural environment for legislative requirements and to meet business drivers.

This reference contains relational and tabular datasets for Aquatic Monitoring for Climate Change - Fish Assemblage and Habitat survey (PRIMR IDs: FF01RKTN00-035, FF01RLPO00-089, FF01RMLH00-125, FF01RWLP00-108, FF01RWMF00-084). These datasets represent ongoing long-term aquatic health and climate change monitoring at Refuges, and incorporates all continuous measures from the pilot project. Service programs (Refuges, Fish and Aquatic Conservation, and Water Resources) are collaborating to implement a long-term aquatic monitoring program for evaluating effects of climate change at National Wildlife Refuges (NWRs) in the Columbia-Pacific Northwest Region (IR9). The goal is to evaluate evidence of climate change on physical and habitat variables, and potentissociations al associations with changes in fish assemblages in wadeable streams. The program relies on two site specific protocols (SSPs), one addressing habitat and fish surveys (this SSP) and another addressing temperature and stream flow. For habitat and fish, objectives are to: establish a survey reach within a stream at each of five NWRs across the range of ecoregions in IR9; describe habitat in each survey reach once every five years or less; describe fish assemblages in each survey reach once every five years or less; analyze for temporal changes in habitat and fish assemblages, and assess potential temporal associations between habitat and fish assemblages. Data collected at survey reach are based on a subset of protocols developed by the U.S. Environmental Protection Agency for the Environmental Monitoring and Evaluation Program (EMAP; Peck et al. 2006).

This record is for Approval for Access (AfA) product AfA436. This dataset shows the names and locations where the Environment Agency carries out planned, routine environmental monitoring. Details of monitoring sites operated by third parties, for example as a condition of their permit, are not included. The monitoring programmes are those considered as ‘environmental monitoring’ by the United Kingdom Environmental Observation Framework (UKEOF). Non-routine monitoring, for example ad hoc or responsive monitoring, is not included. Most site locations are held at a resolution of 1 metre. The grid references of some sites are only shown to a resolution of 1km. This is because some sites are on land owned by individuals, and precise location could infringe personal privacy or national security. Groundwater monitoring is always shown with reduced resolution of 1km. This dataset is available on the Environment Agency’s Datashare site, and will also be combined with other organisations’ data and made available from the UKEOF website.

Beam and otter trawl surveys between Morwellham Quay and West Mud of the River Tamar, southwest England, for smelt and shad, between 2015-08-06 and 2016-03-14 recording total length and representative weights of targeted species and other fishes as part of contract EC18234 between Natural England, the Marine Biological Association and the Environment Agency.

Marine chemistry, fish / shell-fish surveys, benthic organisms, and marine toxic substances and pollutants data were collected using current meter and other instruments from J.W. POWELL and other platforms in the Gulf of Mexico. Data were collected from 26 January 1993 to 13 June 1994. Data were submitted by Dr. Gary Wolf of Texas A&M University with support from the Gulf of Mexico Offshore Operations Monitoring Experiment (GOOMEX). Data has been processed by NODC to the NODC standard F069 (Marine Chemistry), F123 (Fish/Shell-fish Surveys), F132 (Benthic Organisms), and F144 (Marine Toxic Substances and Pollutants) formats. The F069 format is used for data from chemical analyses of seawater samples. Cruise information, position, date, and time is reported for each station along with sample depth, temperature, salinity, and density (sigma-t). Chemical and biochemical parameters that may be reported include: dissolved oxygen, nitrate, nitrite, ammonia, inorganic phosphate, and silicate; dissolved organic carbon, particulate organic carbon, and particulate organic nitrogen; and apparent oxygen utilization, percent oxygen saturation, adenosine triphosphate, total phaeophytin, total chlorophyll, total suspended matter, total recoverable petroleum hydrocarbons, and total resolved light hydrocarbons. The F123 format is used for data from field sampling of marine fish and shellfish. The data derive from analysis of midwater or bottom tow catches and provide information on population density and distribution. Cruise information, position, date, time, gear type, fishing distance and duration, and number of hauls are reported for each survey. Environmental data may include meteorological conditions, surface and bottom temperature and salinity, and current direction and speed. Bottom trawl or other gear dimensions and characteristics are also reported. Catch statistics (e.g., weight, volume, number of fish per unit volume) may be reported for both total haul and for individual species. Biological characteristics of selected specimens, predator/ prey information (from stomach contents analysis), and growth data may also be included. A text record is available for comments. The F132 contains data from field sampling or surveys of bottom dwelling marine organisms. The data provide information on species abundance, distribution, and biomass; they may have been collected by point sampling (grab or core), by tow (dredge, trawl or net), by photographic surveys, or by other methods. Cruise information such as vessel, start and end dates, investigator, and institution/agency; station numbers, positions and times; and equipment and methods are reported for each survey. Environmental data reported at each sampling site may include meteorological and sea surface conditions; surface and bottom temperature, salinity and dissolved oxygen; and sediment characteristics. Number of individual organisms and total weight of organisms is reported for each species. A text record is available for comments. The F144 contains data on ambient concentrations of toxic substances and other pollutants in the marine environment. The data derive from laboratory analyses of samples of water, sediment, or marine organisms. Samples may have been collected near marine discharge sites or during ocean monitoring surveys of large areas. Field observations of tar deposits on beaches may also be reported. Survey information includes platform type, start and end dates, and investigator and institution. If data are collected near a discharge site, discharge location, depth, distance to shore, average volume, and other characteristics are reported. Position, date, time and environmental conditions are reported for each sample station. Environmental data may include meteorological and sea surface conditions, tide stage and height, depth of the thermocline or mixed layer surface temperature and salinity, and wave height and periods. Sample characteristics, collection methods, and laboratory techniques are reported for each sample collected and analyzed. The data record comprises concentration values (or a code to indicate trace amounts) for each chemical substance analyzed. Chemical substances are identified by codes based on the registry numbers assigned by the Chemical Abstracts Service (CAS) of the American Chemical Society. Marine organisms from which samples have been taken are identified using the 12-digit NODC Taxonomic Code. A text record is available for optional comments.

This visualization product displays the fishing & aquaculture related plastic items abundance of marine macro-litter (> 2.5cm) per beach per year from non-MSFD monitoring surveys, research & cleaning operations.

EMODnet Chemistry included the collection of marine litter in its 3rd phase. Since the beginning of 2018, data of beach litter have been gathered and processed in the EMODnet Chemistry Marine Litter Database (MLDB).

The harmonization of all the data has been the most challenging task considering the heterogeneity of the data sources, sampling protocols and reference lists used on a European scale.

Preliminary processings were necessary to harmonize all the data:

• Exclusion of OSPAR 1000 protocol: in order to follow the approach of OSPAR that it is not including these data anymore in the monitoring;

• Selection of surveys from non-MSFD monitoring, cleaning and research operations;

• Exclusion of beaches without coordinates;

• Selection of fishing and aquaculture related plastic items only. The list of selected items is attached to this metadata. This list was created using EU Marine Beach Litter Baselines, the European Threshold Value for Macro Litter on Coastlines and the Joint list of litter categories for marine macro-litter monitoring from JRC (these three documents are attached to this metadata). The selection was adapted to the Joint list of litter categories fishing gears identification and therefore contains some differences with the selection made for previously published versions of this product;

• Exclusion of surveys without associated length;

• Normalization of survey lengths to 100m & 1 survey / year: in some case, the survey length was not 100m, so in order to be able to compare the abundance of litter from different beaches a normalization is applied using this formula:

Number of fishing & aquaculture related plastic items of the survey (normalized by 100 m) = Number of fishing & aquaculture related items of the survey x (100 / survey length)

Then, this normalized number of fishing & aquaculture related plastic items is summed to obtain the total normalized number of fishing & aquaculture related plastic items for each survey. Finally, the median abundance of fishing & aquaculture related plastic items for each beach and year is calculated from these normalized abundances of fishing & aquaculture related items per survey.

Percentiles 50, 75, 95 & 99 have been calculated taking into account fishing & aquaculture related plastic items from other sources data for all years.

More information is available in the attached documents.

Warning: the absence of data on the map does not necessarily mean that they do not exist, but that no information has been entered in the Marine Litter Database for this area.
