| Comments: | Tetsuma Akahoshi brought over 90 black bass from California in 1925 (Ref 45327). Introduced into Lake Ashinoko and initial transplantation into other lakes was unsuccessful. Since the species was a favorite among the anglers they secretly transplanted the fish into many lakes despite the prohibition by the government therefore causing serious problems on native fish species. Preys on native fishes (Ref. 6094). Lake Biwa catch for native species has dropped from more than 8000 tons in 1972 to 2174 tons in 2000 while experts estimate catch of exotic species (black bass and bluegill exceed 3000 tons (Ref. 45327). Social and ecological problems have been experienced recently pertaining to the 'black bass problem.' (Ref. 55372). Considered to be one of the most damaging alien species in Japan (Ref. 53025).
