Summary

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).
