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.

Abstract

Funding

Stated preference choice experiment data were collected in conjunction with NMFS’ Marine Recreational Fisheries Statistics Survey (MRFSS) along the coastal states of Maine, New Hampshire, and Massachusetts during 2014. All anglers intercepted in Maine, New Hampshire, and Massachusetts for NMFS' Marine Recreational Information Program (MRIP) intercept survey were asked to participate in a voluntary follow-up mail survey. Anglers who agreed to participate in the follow-up were sent mail questionnaires using a modified Dillman Tailored Design. The choice experiment survey asked anglers that have targeted Gulf of Maine cod, haddock, or pollock to simultaneously compare features of different hypothetical fishing trips and then to choose the trip they liked best. The features or attributes varied across trips and included bag and size limits of each species, the number of legal-sized fish caught of each species, the number of sub-legal sized fish caught of each species, the number of other types of fish that were legally kept, the trip length in hours, and the total trip cost. Respondents were also permitted to choose an opt-out option which was “Do something else: Freshwater fishing, Saltwater fishing for species other than cod, haddock and pollock, or don't go fishing.†The collection of choice responses from the various choice scenarios allows for the examination of tradeoffs and behavioral responses to various biological and regulatory changes. A total of 1,763 surveys were mailed out and 481 completed mail surveys were returned for a response rate of 27%.

Survey used to quantify the species and biomasses of fish caught and type of fishing gear used by fishers in the Lower Tocantins River in the Brazilian Amazon.

This dataset consists of fisheries collection information from the Florida Fish and Wildlife Conservation Commission's Division of Fisheries regional and field offices. The dataset was developed to identify and map freshwater species occurrences throughout Florida. These data are the results of data collection/processing by the Florida Fish and Wildlife Conservation Commission for many federally funded fisheries projects. These data were compiled into a comprehensive and standardized fisheries database for the Florida Fish and Wildlife Conservation Commission from various data programs and paper files. Collection location coordinates were based upon limited global positioning system (GPS) information, written information, the use of digital orthophoto quadrangles, digital raster graphic maps, and ArcView programs to obtain an estimated latitude and longitude for each fish collection site.

Description:

All fish catch data of all methods across all streams sampled at the SAFE project, Danum Valley and surrounding oil palm areas. Please note this is the raw dataset and may contain errors that need correcting/editing. I have tried to correct the majority of errors, but all were corrected in seperate files prior to analysis, so please see specific datasets in relation to specific papers already published. All changes are detailed in the notes column or listed here if more general.

All Rasbora caught in 2013 are labelled as cf. sumatrana as they were not differentiated from R. hubbsi. All Systomus changed to Barbodes. All Tor labelled as T. tambra, with no differentiation between tambra and tambroides. From 2018 onwards, all R. sumatrana have been renamed as R. pycnopeza. New captures were not pit tagged. Fish mortality are tracked in the data.

In 2018, some sites were sampled twice.

In this version, several changes and new spreadsheets have been added on top of previous versions. This includes: 1. Electrofishing setup - the voltage used in electrofishing corresponding to the conductivity measured; 2. Stream _variables along transect- detailed environmental data collect along transect at each site; 3. Riparian survey, with data on the riparian surveys along the fishing transect. The sheet "Data" has been renamed Capture_Data. Environmental data 2017 sheet has been renamed and updated to Environmental Data site level, to include summarized data by site and by year.

The Biodiversity Science Database is a compilation of fish community data from DFO Science Surveys. Data includes: sampling site, date, fish counts, fish species, and associated habitat information. This database was established to support fish species at risk research through the DFO Species at Risk Program and is used primarily for updating the current status of fish species at risk populations across Southern Ontario. The dataset has been constrained to sampling site characteristics for placement on Great Lakes DataStream; the original is available via the Government of Canada Open Data portal, see Data Source URL.

This EnviroAtlas dataset includes the total number of recreational days per year demanded by people ages 18 and over for freshwater fishing by _location in the contiguous United States. These values are based on 2010 population distribution, 2011 U.S. Fish and Wildlife Service (FWS) Fish, Hunting, and Wildlife-Associated Recreation (FHWAR) survey data, and 2011 U.S. Department of Agriculture (USDA) Forest Service National Visitor Use Monitoring program data, and have been summarized by 12-digit hydrologic unit code (HUC). This dataset was produced by the US EPA to support research and online mapping activities related to the EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

This dataset corresponds with the inland fisheries collaboration between the Land and Water Lab at the University of Florida and Food and Agriculture Organization of the United Nations. An online survey of fisheries professionals distributed in June-September 2020 yielded 536 responses from 93 unique hydrological basins across most major freshwater habitat types. Provided here are the raw survey dataset generated from participant responses, a formatted dataset intended for reuse, a reference key to numeric values and column headers, a reference key to region identifiers, and the script used to generate the formatted dataset and figures used in the paper titled, "A global dataset of inland fisheries expert knowledge."

Recreational fisheries have high economic worth, valued at $190B globally. An important, but underappreciated, secondary value of recreational catch is its role as a source of food. This contribution is poorly understood due to difficulty in estimating recreational harvest at spatial scales beyond an individual system, as traditionally estimated from angler creel surveys. Here, we address this gap using a 28-year creel survey of ~300 Wisconsin inland lakes. We develop a statistical model of recreational harvest for individual lakes and then scale-up to unsurveyed lakes (3769 lakes; 73% of statewide lake surface area) to generate a statewide estimate of recreational lake harvest of ~4200 t and an estimated annual angler consumption rate of ~3 kg, nearly double estimated United States per capita freshwater fish consumption. Recreational fishing harvest makes significant contributions to human diets, is critical for discussions on food security, and the multiple ecosystem services of freshwater systems.

Lake Erie Biological Station (LEBS), located in Sandusky, Ohio, is a field station of the USGS Great Lakes Science Center (GLSC). LEBS is the primary federal agency for applied fisheries science excellence in Lake Erie. Since 2004, LEBS has participated in a collaborative, multiagency effort to assess forage fish populations in the western basin of Lake Erie. Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based based fishery management, and supports decision making that considers food-web interactions. The objectives of this survey were to provide estimates of densities of key forage and predator species in the western basin of Lake Erie, to assess seasonal and spatial distributions of fishes, and to assess year class strength. In 2012 the original vessel used since 2004, the R/V Musky II, was retired and replaced with the R/V Muskie. The change in vessel necessitated changing the gear used to capture fish. Previous surveys used a different catch processing protocol that did not include measurements of biomass or lengths of all species; thus, those historical data are not compatible with the current data format. Under the new protocol, 41 stations were sampled during June (Spring) and September (Autumn). The 2013 western basin survey season marked the first year in which the grid sampling design was employed in both spring and autumn. Thus, we present data starting from 2013. The data sets will automatically update with new data as surveys are completed in future years.

The diversion of freshwater from the Mississippi River is intended to mitigate saltwater intrusion from the Gulf of Mexico and to lessen the concomitant loss of wetland areas. Though effective, freshwater diversion can affect wildlife and habitat; therefore, prediversion and postdiversion data collections are necessary to identify effects. The Davis Pond freshwater diversion area is located between the Mississippi River and Bayou Lafourche and extends to Barataria Bay Basin, Louisiana. Results and interpretations from the prediversion biomonitoring done in 2001- which included data on fish, eagles, and bivalves - are presented in the U.S. Geological Survey (USGS) Scientific Investigations Report 2008-5067, "Davis Pond Freshwater Prediversion Biomonitoring Study: Freshwater Fisheries and Eagles." The postdiversion data generated approximately 6 years later from the sampling of fish whole bodies are presented here in this USGS Data Series. An accompanying log of postdiversion study site photographs was also produced in USGS Data Series 605, "Photographic Images Captured While Sampling for Bald Eagles near the Davis Pond Freshwater Diversion Structure in Barataria Bay, Louisiana (2009-10). Figures 16A and 16C represent the concentration of iron detected in largemouth bass, blue catfish and striped mullet samples collected in 2007-2009, approximately six years after the Davis Pond freshwater diversion structure was operational. Figure 16B compares these concentrations to those collected in the 2001 prediversion study. Samples are from the Mississippi River, Lake Cataouatche, Bayou Couba, and Lake Salvador.

The section manages recreational fishing information obtained from ongoing provision of data from Angling Club Field Day Records Book, Angler's Log Book, surveys completed by Fisheries Officers and VFLO surveys. Information is now obtained from licenced charter boat operators who have been providing returns since September 2001.

The section also monitors the general public participation rate and satisfaction with recreational fishing and awareness of the Department's various roles annually based on a phone survey. Similarly, information on recreational catch and fishing effort for the abalone, marron, SW freshwater angling and rock lobster fisheries is collected and reported using an annual telephone survey of licence holders.

Time: ongoing.
