Mitten Crab training session

12/2011

North Wales Wildlife Trust, the Pen Llŷn a’r Sarnau SAC, CCW and the Environment Agency are holding a training session on Chinese Mitten Crabs with the support of Environment Wales as part of the North Wales Mitten Crab Project.

This training day is part of a project looking at mitten crabs in North Wales.  Mitten crabs are an invasive non native species which were first found in River Thames in 1935, but since then they have increased dramatically with an established population now in the River Dee, with one individual been found in the River Conwy.  Mitten Crabs can have disastrous consequences for the surrounding area such as the destruction of river banks, out competing local species and consumption of commercial fish larvae.  The project is looking into the river conditions of the Dee and comparing these conditions to the River Clwyd, Conwy and the Mawddach to determine the likelihood of Mitten Crabs invading these rivers. 

The training session will cover survey techniques to look for signs of mitten crabs and also monitoring the environmental conditions of the River.  Please bring suitable footwear and clothing for the outdoor part of the training session and a packed lunch.  Tea and coffee will be provided.

If you have seen a Mitten Crab please report it online www.mittencrabs.org.uk.

The training session will be held at the Royal Ship Hotel, Dolgellau on Saturday 14th January, 10:30 – 14:00.  If you would like to book please e-mail rhianhughes@wildlifetrustswales.org.
