簡短描述
型態特徵 | 形態測量圖
脊椎骨: 59 - 62. Diagnosis: Lateral line 109-119 scales; gill rakers 18-22; pyloric caeca 19-24; vertebrae 59-62 (trunk 25-26, caudal 34-37); body deep, maximum depth about 30 (27.8-29.7)% fork length, minimum 8.6-11% FL; caudal peduncle short (15.8-17.9% FL); head deep, 62.5-81.3% of head length (HL), forehead wide, 15.8-17.9% HL; jaws long - upper jaw 51.6-61.1% HL and lower jaw 65.9-67.5% HL (Ref. 56657).
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).
這種生活在來自嘴巴到中游的薩哈林島的河中。 優勢的形式是半-溯河洄游產卵; 潟湖-河形式與河的形式非常稀罕。 魚在夏天與秋天中特徵為它的攝取食物迴游; 在其他的季節中，它逗留在洞與在潟湖中。 魚預先產卵迴游到到河的阿穆爾河潟湖。 一些魚對於進食移動到來自薩哈林島的河的潟湖。 在 NW 薩哈林島的河中，魚達到 80 公分的長度而且重量超過 5 公斤。 生物學的特性被很少地研究: 魚在 4 的時候在 Pyrki 與 Tengi 的河中成熟+; 成熟的個體在八月被記錄到-十月在有相當迅速的水流的區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)
