Environment Agency: The variety of fish which live in the River Thames has been highlighted by an Environment Agency fisheries survey along the river supported by volunteers from the Zoological Society of London.

Specialist fisheries teams surveyed fish populations at 8 locations on the tidal Thames, between Gravesend and Richmond, and identified 17 different species in total. Fisheries teams have been collecting fisheries data from the tidal Thames since the 1960s, and the information is used to get a picture of the health of the river and protect fish. The survey found dace, smelt and common bream, as well as marine species such as sea bass and flounder. A variety of invertebrates, which are an important food source, and some rare and unexpected fish, such as pogges were also discovered.

Environment Agency River Thames surveys are supported by volunteers from Zoological Society of London (ZSL). The volunteers joined fisheries officers as they carried out the work, which involved netting off small sections of the river and counting the amount of fish in each section. To read more go to:
