The big-mouthed buffalo fish ( Ictiobus cyprinellus ) is, like its smaller relative, the small-mouthed buffalo fish ( I. bubalus ), a freshwater fish from the sucker carp family that is widespread in North America .
distribution
The fish species is native to the Red River and the Milk River in Manitoba and Saskatchewan / Canada , from the Great Lakes to the Ohio River and south of the Mississippi in Texas , Louisiana and Alabama . From its area of origin it was exported to numerous US states such as B. Iowa , North Dakota , South Dakota , Oklahoma , Arizona, and Arkansas . In California , too , loud mouthed buffalo fish were introduced into an aqueduct system. The loud-mouthed buffalo fish lives in the stagnant or slowly flowing water of large rivers, oxbow lakes, reservoirs or shallow lakes with flooded vegetation and muddy bottoms. Sometimes it occurs in swamps as well, because it tolerates low oxygen levels in the water.
description
Ictiobus cyprinellus has a dull olive brown color and dark fins. Like other sucker carp, it has a long dorsal fin, but unlike other species it has a terminal mouth. The Bigmouth Buffalo is on average 35 centimeters long, with ideal living conditions up to 120 centimeters and 29 kilograms. The IGFA record fish was caught in Bastrop north of Monroe / Louisiana and weighed 31.9 kilograms and was 123 centimeters long. In individual cases, depending on the environmental factors, it can live up to 20 years.
Way of life
In spring, when the water temperature rises from April to June, the loud-mouthed buffalo fish migrates upriver to its spawning areas, where the fish eggs attach to aquatic plants. Up to a maximum of 250,000 fish eggs are produced per Rogner. Sexual maturity is reached at around 2 years of age. Adult animals, like carp, can live up to 20 years. Unlike Ictiobus bubalus and Ictiobus niger feeds Ictiobus cyprinellus of zooplankton which it by means of its gill raker filters out. He prefers to stay close to the ground and causes water turbulence by up and down movements, which transport the plankton into his mouth. It prefers warm water with temperatures of 22 to 38 ° C, but the water temperatures should not exceed 26 ° C in order not to impair the development of the fish eggs. Since both species inhabit the same habitat, hybridization between Ictiobus cyprinellus and Ictiobus bubalus often occurs .
use
In the shallow water, the loud-mouthed buffalo fish is often prey to the spearfishing, which is widespread in the USA . Professional fishermen catch it with drift nets, gill nets and trawls. Although its meat has a relatively large number of small bones, it is very popular because of its flavor. The keeping in aquaculture is considered to be relatively unproblematic. The populations of the loud mouthed buffalo fish are classified as not endangered. In some cases, they multiply so strongly that, for example, in Lake Heron, Minnesota, electrical barriers were erected to prevent their further spread. As a sport fish it is sometimes very much appreciated.
