简单描述
检索表 | 型态特徵 | 形态测量图
Distinguished from congeners in Scandinavia and Russia by its maxilla clearly reaching beyond posterior margin of eye in adults. Can be also diagnosed by the combination of the following characters: length of maxilla about 9-11% SL; length of lower jaw about 13-20% SL; body depth about 18-24% SL; overall coloration outside spawning season dark, commonly greyish green above and bright orange or yellow on belly; spots usually bright orange; lips usually yellow, orange or pink (black in Lake Segozero); pectoral, pelvic and anal fins usually greyish red or orange, caudal fin with red or orange posterior edge and white or black lower margin (Ref. 59043).
Body shape (shape guide): fusiform / normal.
Found in large deep lakes, very rarely in rivers. Feeds on fish, amphipods, mollusks, insects and gammarids. Spawning occurs in lakes in shallow water along sand-pebble shores. Reaches up to about 75 cm SL (Ref. 59043).
