Mylocheilus caurinus, the peamouth, peamouth chub, redmouth sucker or northwestern dace, is a species of freshwater ray-finned fish from the family Cyprinidae, the carps and minnows, that is found in western North America. It is the only species in its genus.
River chub is one of the most common fishes in its range. About 20% of North American minnows are considered imperiled. None of the imperiled is a mound builder like the river chub. [6] The main threats it faces are pollution, siltation, and habitat destruction primarily by dam building. Like many minnow species it requires flowing water over ...
With over 300 known species, there are more species of minnows native to North America's fresh waters than any other fish. [2] Minnows can be hard to distinguish because many look alike. [3] All minnows have one dorsal fin, ventral fins near the anus, a lateral line system (in most species), and smooth, round cycloid scales. [4]
Hornyhead chubs have been found in several water bodies in the Minnesota River Basin including the north and south forks of the Yellowbank River, Monigan Creek, Cobb Creek, Whetstone Creek, the North Fork of Whetstone Creek and Gary Creek in Roberts, Grant and Deuel Counties, as well as in Big Stone Lake in Grant County.
Ozark minnows are mostly found in creeks or small rivers that have "gravelly or rocky bottoms and strong, permanent flow", and are often found in schools with other minnow species. [7] In addition, they can be found in pools or near riffles, which are "light rapids where water flows across a shallow section of river". [ 8 ]
The Mississippi silvery minnow has a lateral line on each side of its body. [7] These minnows have a pair of pectoral fins, along with a pair of small pelvic fins. [8] The Mississippi silvery minnow, like many other minnows, have an anal fin, dorsal fin, and a powerful caudal fin. The dorsal fin is very centered between the head and the caudal fin.
Pumps control the current to mimic the natural flows of the Rio Grande. The bottom surface is a mixture of sand, gravel and silt. The breeding goal of the $1.7 million facility was to produce 50,000 minnows this year - with 25,000 minnows to be returned to the river and 25,000 to be retained for future captive spawning.
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species ; only 1,270 of these remain ...
