If anyone catches a barbel with blue dots on it’s belly could you please take a photo and note the location.  Also, if possible, could you weigh and measure the fish. These fish were introduced by the Environment Agency and  it would be very useful to monitor their size and movements. Some will have just a single dot but others will have 3 to identify individual fish.
You can send any information to myself (trevorcottam@btinternet.com) or inform the EA.
