The main purpose of Inland Fisheries Ireland’s NRSP (National Research Survey Programme) and Water Framework Directive (WFD) Rivers, Lakes, and Transitional and Coastal Water (TRAC) sampling programmes is to collect fish stock data relating to fish species composition, abundance and age structure in selected waterbodies nationally. These data are used to calculate Ecological Quality Ratings (EQR’s) for fish ecological status in each waterbody/site, a requirement for the EU Water Framework Directive. Data collected spans 2008 to most recent surveys. Multiple survey data by year are available for individual waterbodies and information from the most recent survey is displayed on the map viewer.    Where sp. or spp. denoted identification is to genus level only. REST (JSON)
