Biosecurity alert for Asian paddle crab

The Government of Western Australia has issued a biosecurity alert after an Asian paddle crab (Charybdis japonica) detection was confirmed this week. The single mature female crab was caught at Blackwall Reach, Swan River, Perth, on 5 December.

The Asian paddle crab is an aggressive non-native crab that could outcompete native species like the blue swimmer and spread diseases to prawns, crabs and lobsters. It varies greatly in colour but its definitive features are six sharp spines between the eyes and six spines down each side of the shell.

The Department of Primary Industries and Regional Development is calling for continued vigilance. Five paddle crabs were previously detected at Mosman Bay in 2012 and Matilda Bay in 2014, and one in Mandurah in 2010.

The Department is undertaking a range of activities including public awareness and communication engagement campaign and trapping surveys in the Swan River are planned for the coming months.
