Comments: Found in Hokkaido (Ref. 37812). Also recorded from Lake Biwa (Ref. 78994). Considered a delicacy in Japan and a cooking method has been developed wherein live dojo are dropped in a pot of cold water containing a block of bean curd (tofu); fish burrow into the tofu and get cooked in it as the water is heated up; the block of tofu when sliced show segments of dojo (Ref. 44091). Status of threat in the 2005 Red Data Book of Shiga Prefecture: data deficient so caution needed (Ref. 79825). Also Ref. 27732, 43281. Status of threat: Data deficient (Ref. 94887).

Asia: Native to Siberia (Tugur and Amur drainages), Sakhalin, Korea, Japan, China south to northern Vietnam. Europe: Introduced in several localities in Rhine (Germany) and Ticino (Italy, north of Milano) drainages, Aral Sea basin, North America, Australia and Hawaii. This species proved successful in the aquarium fish trade and has also been introduced to other countries (Ref. 1739). At least one country reports adverse ecological impact after introduction.

Description synthétique Clés d'identification | Morphologie | Morphométrie

Dorsal view shows the male with larger pectoral fins and the female with fuller abdomen (Ref. 44091). Body is mottled with darker greenish-gray to dark brown markings, against a yellow-brown to brown color; conspicuous adipose crests along the ventral and dorsal mid-lines of the caudal peduncle; 10 barbels; suborbital spine hidden in the skin (Ref. 27732).

Facultative air-breathing (Ref. 126274); Occurs in rivers, lakes and ponds. Also in swamps and ricefields (Ref. 27732, 119549). Prefers muddy bottoms, where they hide in the muck and leaf litter with only their heads sticking out; prefers muddy bottoms of streams and ponds; in Hawaii, can also be found under mats of honohono (Commelina diffusa and California grass (Brachiara nuatica); feeds on worms, small crustaceans, insects, insect larvae, and other small aquatic organisms (Ref. 44091).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

Male wraps his body around the female and stimulates her to release a cloud of eggs, which the male simultaneously fertilizes (Ref. 44091).
