Short description
Identification keys | Morphology | Morphometrics
Distinguished from congeners in British Isles by the following characters: body coloration plain purplish-brown (silvery to goldish outside spawning season), belly creamy-pink to light orange in large individuals; eye large, about 3.7-4.0 times in HL; snout blunt; pectoral fin equal to or longer than head, sometimes almost reaching pelvic origin in large males; pectoral, pelvic and anal fins reddish; pelvic and anal fins with white anterior margin, very narrow in pectoral; maxilla reaching posterior margin of eye or beyond (Ref. 59043).
Inhabits lakes. Feeds on zooplankton in summer and on benthic invertebrates for the rest of the year. Spawns over gravel and stones in shallow water, along stone shore line (Ref. 59043).
