Ecology and Fish Data


The Ecology and Fish Data API provides access to the Environment Agency's open data on freshwater fish data, as well as freshwater and marine ecology survey data. This data collection is taken from the National Fish Populations Database (NFPD) and Biosys (Biological survey database).

The Ecology and Fish Data API uses a data model that harmonises these different sources, so that measurements taken for variety of purposes can be queried in a consistent way.The most central points of interest are the Observations. Each observation has a single result for a particular Observable Property for a particular Feature of Interest.
