Freshwater fish surveys - salmonid age data (NFPD)

Alternative title(s)

National Fish Populations Database (NFPD) Salmonid age data

Abstract

The Environment Agency undertakes fisheries monitoring work on rivers, lakes and transitional and coastal waters (TraC). This dataset includes site and survey information, together with a detailed breakdown of the salmonid age data into numbers of 0+, >0+, 1+, >1+ age bands (where available), for 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 dataset 'Freshwater fish surveys (NFPD)' may also be relevant, it contains fish lengths, weights, and the raw age data (where available).
