ສັດທີ່ມີກະດູກສັນຫັຼງ
ການຖ່າຍທອດທາງກຳມະພັນຈາກພໍ່ແມ່ຫາລູກ: 0; ຄີກົ້ນຂອງປາ: 10 - 14; ສັດທີ່ມີກະດູກສັນຫຼັງ: 49 - 55. Body elongate, almost cylindrical. Head elongate, its length slightly greater than body depth; eye relatively large, its diameter greater than snout length; snout bluntly rounded, overhanging mouth, not obviously pointed, a single flap of skin present between nostrils. Nuptial tubercles developed in both males and females, but more conspicuous in males, and occur on top of head, on scales on back and sides, and on paired fins. Body is brownish above, silvery on sides and white below. Dorsal, caudal, and pectoral fins usually clear, anal and pelvic whitish and immaculate, a faint dark spot sometimes present on base of caudal fin. A series of 12 - 14 similar spots present along the midline of the back, and 7 - 14 dark, round or oval parr marks with diffuse borders present along the lateral line of young and sub adults, although some Alaskan forms retain parr marks even on largest fish.
Body shape (shape guide): elongated; Cross section: oval.
Adults inhabit lakes and rivers of mountainous areas (Ref. 1998). They feed mainly on crustaceans and aquatic insect larvae (Ref. 1998). Minimum depth reported from Ref. 1998.
Moves to spawning grounds in the early winter and presumably back into deeper water after spawning. Spawns at night, presumably the eggs are broadcast, settling into interstices in the gravel. Hatching occurs the following spring (Ref. 27547).
