Abstract

Genetic confirmation of Mya japonica Jay, 1857 (Bivalvia: Myidae) in Tasmania, Australia: first record of any species of Mya in the southern hemisphere.

Abstract

The Japanese soft-shelled clam Mya japonica Jay, 1857 is native to the northwestern Pacific Ocean but has invaded the northeastern Pacific Ocean, North Atlantic Ocean, Barents Sea and Mediterranean Sea. Here, we confirm its presence in the southern hemisphere using mitochondrial COI, 16S rRNA and nuclear 28S rRNA gene sequences. These analyses permit us to distinguish it genetically from its equally invasive congener, M. arenaria Linnaeus, 1758. We found M. japonica to be well established in one location on the southeast coast of Tasmania.
