''Notropis percobromus'' (carmine shiner) is a freshwater fish species. In Manitoba, it was once known as the rosyface shiner (''Notropis rubellus''). It is now recognized as a different species within the rosyface shiner species complex, largely based on zoogeographic information. The carmine shiner is a member of the Minnow family, Cyprinidae. It has the following characteristics and distinguishing features: * A slender, elongate minnow, typically 55 to 60 mm in length (Whitemouth River) * Snout length is equal to the eye diameter * Adults are olive green dorsally, silvery on the sides and silvery white on the belly * Black pigment outlines the scale pockets dorsally; the opercula and cheeks may be pinkish * Breeding males develop fine, sandpaper-like nuptial tubercles on the head, pectoral fins and some predorsal scales. They also turn pinkish violet around the head with a reddish tinge at the base of the dorsal fin. Breeding females are usually lighter in colour * Seldom survives capture or handling and scales are easily dislodged == Distribution == In Canada, this species has been found only in the Winnipeg River system, including the Whitemouth watershed. It may occur upstream to Lake of the Woods, Ontario. The Manitoba populations are at the northwestern limit of the distribution, separated from the continuous range of the species by 450 km. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Notropis percobromus」の詳細全文を読む スポンサード リンク
