“…In addition to earlier introductions to Europe and the West coast of the United States, E. sinensis has colonised Portugal, Spain, Italy and Ireland in the last decades (Cabral and Costa 1999;Rudnick et al 2003;Garcia-de-Lomas et al 2010;Crocetta et al 2020) and has been reported in the Tokyo Bay of Japan (Takeda and Koizumi 2005). E. japonica has been reported on the west coast of North America (Jensen and Armstrong 2004) and E. hepuensis, native to China, has been introduced to Iraq (Naser et al 2012) and Iran (Naderloo 2014). These new findings warn us that mitten crabs are still on the move.…”

Cryptic biological invasions are largely unrecognised, leading to an underestimation of the number of invading taxa and their potential impacts. The Chinese mitten crab, Eriocheir sinensis, is a highly invasive species with serious economic and ecological impacts in Europe. Recently, mitochondrial DNA (mtDNA) of the Japanese mitten crab, E. japonica, has been discovered in populations from The Netherlands, Poland and Germany, but the taxonomic status and time of introduction of specimens carrying this mtDNA are uncertain. To this end, we investigated the morphology and variation of the mitochondrial cytochrome c oxidase subunit I (COI) gene of mitten crabs collected in central-western Europe between 1998 and 2020. Mitten crabs from Belgium harboured a Japanese mitten crab COI haplotype in 33% to 65% of individuals, even in our earliest samples from 1998. All other studied populations carried only Chinese mitten crab COI haplotypes. Morphologically, many of the juvenile Belgian mitten crabs showed intermediate traits between the two species, while all investigated adult mitten crabs, regardless of their mitochondrial haplotype or country of origin, were morphologically assigned to E. sinensis. This intermediate morphology of the juveniles and genetic-morphological discrepancy of adults suggests that Japanese mitten crabs introgressed with Chinese mitten crabs, which could have happened both before and after the introduction of mitten crabs to Europe. A specific Chinese mitten crab COI haplotype, found in Belgium, was previously only known from Vladivostok (Russia), where Chinese and Japanese mitten crab hybrids naturally occur. This Far East region is, therefore, a plausible source for at least part of the mitten crab mitochondrial diversity in Belgium.

“…In addition, E. japonica was also observed on the west coast of North America (Jensen and Armstrong ). E. hepuensis was spotted in Iraq and Kuwait in 2005, which is the first report for this species outside its native range; E. hepuensis may have been present for over 30 yr and has now become well established in Iraq (Naser et al ; Naderloo ).…”

Chinese mitten crab, Eriocheir sinensis, is an important freshwater cultured crab in China with an annual production of approximately 800,000 m.t. and a value of 5 billion US dollars in 2014. The germplasm admixture and degeneration of E. sinensis are the most critical factors that restrict its aquaculture industry. Thus, genetic improvement programs of E. sinensis were initiated in 2000. The Ministry of Agriculture of China approved five selected varieties of E. sinensis, which are currently cultured throughout China and cover nearly 10% of the total yield of E. sinensis. The aquaculture status, genetic improvement practices, and achievement in E. sinensis aquaculture in China during the past 15 yr are summarized in this review.
