Between 2006 and 2013, ZSL monitored the fish populations in the Thames Estuary as part of a long term collaborative project with Tilbury Power Station and the Environment Agency. This long-term data set provides a crucial insight into how fish populations have changed over time, which we can relate to pollution incidents, the overall water quality of the Thames and natural fluctuations in fish populations. We also use this dataset to identify new or rare species visiting the Thames.
Why we are there
The Thames Estuary supports over 120 different fish species, which are important both ecologically and economically. Since being declared “biologically dead” in the 1950’s, the environment has improved significantly and the Thames Estuary is now one of the world's most unpolluted metropolitan tideways. It is important to have long-term fish monitoring, so that we know what fish regularly occur in the Thames Estuary and can detect any changes in fish abundance or species composition.
Tilbury Fish Monitoring
ZSL monitored the fish species passing through Tilbury Power station on a weekly basis, between 2006 and 2013. Analysis of this data is under way, and we will produce a number of reports on key fish species in the coming months.
