Red shiner
American Rotflossenorfe
The American Rotflossenorfe ( Cyprinella lutrensis ), Eng. Red or Red -Horse Shiner Minnow interchangeably, even Notropis lutrensis is a short stature, indigenous to North America in carp fish.
Description
Cyprinella lutrensis has radiation fins (fins formula: 7-8 dorsal fin, anal fin 8-10), an elongated, laterally slightly compressed body and is about 10 inches long. Females as well as males have silvery sides and a whitish belly bottom. The males form the spawning season of a distinctive color pattern, which gave them the name Red Shiner. The edges are pink to purple with blue iridescent facets. The fins have a blood-red hue, except for the dorsal fin, which remains dark. Cyprinella lutrensis is often confused due to their similarity to the European rudd, roach, or the orfe.
Dissemination
Cyprinella lutrensis was caught in Otter Creek, Arkansas for the first time, lutrensis her name, Latin " lutra " means otter. American Rotflossenorfen come originally from the Mississippi basin, from southern Wisconsin and eastern Indiana, about South Dakota and Wyoming to southern Louisiana. Introduced they were in Arizona, Alabama, California, Colorado, Illinois, Georgia, Nebraska, North Carolina, South Carolina, Massachusetts, Utah, Virginia, Nevada and New Mexico. In northern Mexico, you can find the fish. The endemic in the Rio Grande subspecies Cyprinella lutrensis blairi (English: Maravaillas Red Shiner ) is extinct. American Rotflossenorfen are adapted to a wide range of different aquatic habitats, so they can be found for example in the bayous and backwaters of rivers, reservoirs, lakes, estuaries and large rivers that have a sandy or loamy subsoil, rapids and deep water sections. Red Shiner tolerate turbid and troubled waters with a high proportion of substrate, however, are sensitive to acidic waters. American Rotflossenorfen are considered generalists in terms of their habitat and can also spread to marginal locations such as channelized ditches, polluted waters and periodically dry falling waters where other fish species are no longer living conditions.
Way of life
American Rotflossenorfen can be up to three years old. They are omnivorous, feeding on both algae, aquatic invertebrates and insects that fall into the water. Cyprinella lutrensis is known to them as the robbers spawning nests of other species of fish eats, especially in waters where the type of people has been introduced. The spawning season of the American Rotflossenorfen takes place in mid-April to September, with peak in mid-summer in the months. Rather than storing the spawning in columns, like other members of the genus Cyprinella, looking on American Rotflossenorfen Stone Ground water and vegetation for oviposition. Females lay up to 16 bands from spawning with about 71 eggs per spawning band. American Rotflossenorfen often spawn together with other species such as the Blue Shiner or Blacktailed Shiner, so it is easy for hybridization of species. They live in flocks in the middle or near the surface of water.
Use
American Rotflossenorfen are commonly used in the U.S. for its lively color than bait fish predator fishing. Mainly introduced in this way by anglers in new waters, they have in their new habitat often proliferated and endemic fish species decimated by eating eggs. Because of their great adaptability, even at unfavorable locations, they have many other fish species displaced. By hybridization with the Blacktailed Shiner ( Cyprinella venusta stigmatura ), who lives in Georgia endemic to the Coosa River, they have diluted the gene pool of this kind. The American Rotflossenorfen are held in groups as undemanding and colorful ornamental fish for a cold-water aquarium suitable.
