Abstract

Reappearance of Rhithropanopeus harrisii (Gould, 1841) (Crustacea, Decapoda, Brachyura) in U.K. waters: a new record from the river Thames, London.

Abstract

The invasive American Harris mud crab is reported for the first time from the Thames catchment in proximity to East India Dock basin and the confluence with the River Lea (Bow Creek), East London. Rhithropanopeus harrisii (Gould, 1841) has only once previously been recorded in British waters from Roath Docks, Cardiff, South Wales. Although the current status of R. harrisii in Roath Dock and the Thames at Bow Creek requires clarification, the Harris mud crab has been established in North European estuaries since 1874 and has spread rapidly elsewhere.
