Title: West Thurrock fish survey 1990-91
Author: National Rivers Authority Thames Region
Document Type: Monograph
Abstract:
Thames Water biologists first began monitoring the macrofauna in the Thames Estuary in 1974 primarily to monitor the recovery of the tideway biota after improvements to the major sewage treatment works at Beckton and Crossness. Much of this work was curtailed during the mid 1980s but was restarted during the transfer of the regulatory function of the Authority to the National Rivers Authority. This report summarises the results of fish surveys undertaken at West Thurrock Power Station in 1990 and 1991. and can be read in conjunction with the two earlier reports of 1988 and 1989. The aim of the report is to present the results of the surveys and no inferences on water quality will be made. Use of the data to assess water quality will be the subject of other specifically targetted reports. This approach parallels that being taken with estuarine macroinvertebrates and meiofaunal data.
