“…The maximum FISK score for a foreign species was recorded for Rhodeus ocellatus ocellatus. This species has had a serious hybridization impact on the native Japanese rosy bitterling, R. ocellatus kurumeus (Kawamura et al 2001), with a gradual expansion of its distribution in northern Kyushu Island . Native populations of R. ocellatus ocellatus are primarily distributed in continental East Asia (Matsuzawa and Senou 2008), under similar climatic conditions to populations in Kyushu Island (Peel et al 2007).…”

“…For example, in Japan, numerous studies have reported diverse information on alien fishes, such as reproduction and feeding (Azuma and Motomura 1998;Iguchi et al 2004), genetic structure and diversity (Kawamura et al 2006;Yonekura et al 2007), competition (Taniguchi et al 2000;Sahara 2005), hybridization (Kawamura et al 2001;Konishi et al 2003), and genetic homogenization between different populations ). However, risk assessment and management studies of species invasions remain limited (Sato et al 2010a, b).…”

The potential invasiveness of 28 freshwater fishes in northern Kyushu Island, Japan, was evaluated using the Fish Invasiveness Scoring Kit (FISK). The five co-authors scored the level of invasiveness for each species and calculated the total FISK scores; the maximum and minimum scores were then eliminated, and the mean of the remaining three scores was used as the final score for each species. The mean scores ranged from 11.0 (Hypomesus nipponensis) to 31.0 (Cyprinus carpio). The receiver operating characteristic curve indicated that the threshold value between fishes that present a high risk of invasion and the other species were 19.8.

“…These areas are mostly included within actual Rok distributions. Several studies report the hybridization between these subspecies (Nagata 1980(Nagata , 2005Nagata et al 1996;Kawamura et al 2001;Kawamura 2005), and Rok risks extinction through hybridization with Roo (Kawamura et al 2001). Roo was also categorized as an invasive species in northern Kyushu using the Fish Invasiveness Scoring Kit (FISK; Copp et al 2005a, b) in our previous study ).…”

“…Previous reports on distributions of mitochondrial DNA (mtDNA) from Rok and Roo in Kyushu have indicated that three types of populations exist: one with only Rok mtDNA, one with only Roo mtDNA, and one that contains a mixture of both mtDNAs (Miyake et al 2008). Since several studies reported the hybridization between these subspecies (Nagata 1980(Nagata , 2005Nagata et al 1996;Kawamura et al 2001;Kawamura 2005), we treated the populations with only Rok mtDNA as Rok populations, and the other populations as Roo.…”

The distributions of seven bitterling species and subspecies-Tanakia lanceolata, T. limbata, Acheilognathus tabira nakamurae, A. rhombeus, Rhodeus ocellatus kurumeus, R. ocellatus ocellatus, and R. atremius atremius-in northern Kyushu were predicted using generalized linear models (GLMs) in order to provide information helpful for conserving native bitterlings and preventing the expansion of alien bitterling species. Predictions were made according to the following procedure: (1) a set of GLMs for each species was formulated using environmental data from 710 sites that were derived using digital maps and GIS software, from which the best fit model for each species was selected using the Akaike information criterion for predicting the fish occurrence, (2) model performance was evaluated based on the receiver-operating characteristics (ROC) analysis using occurrence and environmental data from 362 sites, and (3) potential distributions of the bitterling were analyzed using the best fit models and environmental data for 1,272 sites, of which 200 data points without occurrence data were prepared.The best fit models revealed that 4-6 environmental factors were important in predicting seven bitterling distributions, which was supported by the area under the ROC curve (AUC) values of these fishes ranging from 0.753 to 0.927.The AUC values in model evaluation were significantly greater than 0.5 for six fishes, suggesting the moderate accuracies of these best fit models for predicting the fish distributions. These predictive models can be used for evaluating potential native bitterling richness and the potential distribution expansion of an alien subspecies.

Pseudorasbora pumila pumila was collected to investigate its genetic relationships from 11 localities in Hokkaido and eastern Honshu of Japan with Pseudorasbora parva from 6 localities in Hokkaido, eastern Honshu, and Polovynka River (a tributary of the Amur River in eastern Russia) in 1996-1998. In Hokkaido and Akita prefectures (Honshu), three P. pumila pumila populations were distributed with P. parva sympatrically. Samples of P. pumila pumila and P. parva were analyzed based on 27 allozyme loci. Genetic differentiation between P. pumila pumila and P. parva (D = 0.522-0.622, average 0.601) was almost equal to or greater than that between other congeneric fish species previously reported. In the three sympatric populations of two species, which had arisen from artificial transplantation of the latter into localities of the former, the individual frequency composition of genetic types (P. pumila pumila, P. parva, F 1 hybrid, and later filial generation hybrid) were significantly different from each other. Differing from the previous studies, F 1 hybrids were fertile and coexisting populations of the two species included the F 1 hybrid and the later filial generation hybrid. These results suggest that genetic population dynamics of sympatric populations of the two species would be influenced not only by hybridization but also by ecological and environmental factors. Alternatively, the existence of populations that possessed both the alleles specific to P. pumila pumila and those specific to P. parva may indicate that introgressive hybridization, instead of species displacement, has occurred between the two species under a certain condition.
