Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what information they have on which different species of fish inhabit the tidal reaches of the River Thames, particularly in the Richmond and Teddington sections.

The Environment Agency (EA) is responsible for managing freshwater fisheries in England and carries out biannual fish surveys at eight locations on the tidal Thames, between Gravesend and Richmond.

From 2010-2022, the EA recorded 19 fish species at Richmond. These were: bleak; brown trout; bullhead; chub; common bream; common carp; dace; European eel; flounder; common goby; gudgeon; minnow; perch; roach; rudd; sand smelt; sea bass; smelt; and three-spined stickleback.

Teddington has not been surveyed recently but between 1989 and 1993 11 species were caught at Teddington. These were: bleak; common bream; common goby; dace; European eel; flounder; gudgeon; perch; roach; sea bass; and three-spined stickleback.
