Invasion Description

1st Record: Nagoya, Honshu/Japan/Nakagawa Canal, Ise Bay (Iseda 2007, Doi et al. 2011)

(Iseda, Masatsugu; Otani, Michio; Kimura, Taeko, 2007. First Record of an Introduced Crab Rhithropanopeus harrisii (Crustacea: Brachyura: Panopeidae) in Japan. Japanese-Journal-of-Benthology. 62: 39-44)

Abstract- 'To date, the panopeid crab Rhithropanopeus harrisii has been found widely in brackish waters in North America and Europe. We report here the first record of R. harrisii as an introduced crab in Japan, on the basis of 86 specimens (47 males and 39 females) collected in July, 2006, from the Nakagawa Canal, which connects with Nagoya Port in the innermost part of Ise Bay on the Pacific coast of central Japan. Fragmentary evidence suggests that this crab may have settled in the area at least by 2000. A brief morphological description of the crab and a comparison between it and the native pilumnid crab Pilumnopeus makianus is made in order to facilitate easy recognition, because the two species are superficially similar and sympatrically occur in local waters.'
