The Environment Agency report that thirteen bream captured from Tottenham Lock on the River Lee have been tagged with acoustic tags and released back into the river; receivers that can detect the tags have been positioned along 8 km of the river. As the fish swim past the receivers their presence is logged, allowing the EA to download the data at regular intervals.
The River Lee is a challenging environment for fish; the heavily urbanised channel and regular incidents of poor water quality limit the potential of the fishery. The breams’ movements will be tracked for 18 months, and the information obtained will reveal the habitats where these fish congregate, spawn and move to during the periods when water quality is poor thus allowing the identification of key locations with the aim of improving and protecting the critical areas in the future.
