Kort beskrivning Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 9 - 11; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 7; Ryggkotor: 45 - 47. Distinguished by the sucking mouth located on the ventral sides of the head and thick papillose lips (Ref. 27547). Gill rakers short; lateral line complete, inconspicuous; caudal tips slightly rounded (Ref. 27547). Adults may be reddish brown, dark brassy green or black above, paler on the lower sides, with the ventral parts white; young fish are usually dark gray with small black spots; breeding males are usually dark above with a brilliant reddish stripe along each side, while females are greenish gold to copper, with a less brilliant red stripe; breeding males show prominent tubercles on the rays of the anal and caudal fins and also on the head (Ref. 27547).
Body shape (shape guide): fusiform / normal.
Body shape (shape guide): fusiform / normal.
Found in clear, cold, deep water of lakes and tributary streams; occasionally found in brackish water in the Arctic (Ref. 5723). Adults move from lakes into inlet streams or from slow, deep pools into shallow, gravel-bottomed portions of streams to spawn (Ref. 27547). They feed on benthic invertebrates (Ref. 1998). Young are preyed upon by other fishes and fish-eating birds; while adults in spawning streams are taken by mammals, osprey and eagles (Ref. 1998). Utilized as a food fish or as dog food (Ref. 27547).
Livscykel och parningsbeteende Könsmognad | Reproduktion | Lek | Ägg | Fekunditet | Larver
Spawns only during daytime (Ref. 27547). At spawning, males lie close to the bottom in the current of the spawning area while females stay along the banks and in still water (Ref. 27547). A female moves from the bank of the stream usually escorted by 2-4 males to the spawning area at the center of the stream. The males crowd beside her; egg deposition occurs as the males try to clasp the female with their pelvic fins or vibrate against her with their anal fins. This spawning act lasts for 3-5 seconds and may occur as often as 6-40 times per hour. After the eggs are deposited, the sexes separate and return to their previous stream positions (Ref.1998). Fish that moved out of a lake to spawn generally return to the lake a few days after spawning. However, river-resident fish may stay on or near the spawning area for much of the summer (Ref. 27547). Many spawn in two or even three consecutive years but others may skip one or two years between spawning (Ref. 10928).
