This species lives in rivers of Sakhalin from the mouth to the middle reaches. The dominant form is semi-anadromous; lagoon-river form and the riverine form are much rarer. The fish is characterized by its feeding migrations in the middle of summer and autumn; in other seasons, it remains in holes and in the lagoon. Fish ready to spawn migrate to the Amur lagoon to rivers. Some of the fish move to the lagoon from rivers of Sakhalin for feeding. In rivers of NW Sakhalin, fish reach a length of 80 cm and weigh more than 5 kilos. Biological characteristics are rarely studied: the fish mature in the rivers of Pyrki and Tengi at the age of 4+; mature individuals noted in August-October in areas with relatively rapid current and sandy or pebbled bottom in holes (up to 1.5-2 meters0, the chars may even winter here; omnivorous, feeding on fish, aerial and aquatic insects and their larvae, amphipods, on insectivorous mammals and mice (Ref. 56657).
这种生活在来自嘴巴到中游的萨哈林岛的河中。 优势的形式是半-溯河洄游产卵; 舄湖-河形式与河的形式非常稀罕。 鱼在夏天与秋天中特征为它的摄取食物回游; 在其他的季节中，它逗留在洞与在舄湖中。 鱼预先产卵回游到到河的阿穆尔河舄湖。 一些鱼对于进食移动到来自萨哈林岛的河的舄湖。 在 NW 萨哈林岛的河中，鱼达到 80 公分的长度而且重量超过 5 公斤。 生物学的特性被很少地研究: 鱼在 4 的时候在 Pyrki 与 Tengi 的河中成熟+; 成熟的个体在八月被记录到-十月在有相当迅速的水流的区域中與沙的或小圓石底部在洞中 (向上到 1.5-2 公尺 0, 零碎工作可能平坦的冬天在這裡; 雜食性的, 吃魚，天線與水生昆蟲與他們的幼體，片腳類動物, 在食蟲的哺乳動物與老鼠上.(參考文獻 56657)。
