See text Pantosteus Cope, 1875 Catostomus is a genus of fish belonging to the family Catostomidae, commonly known as suckers.

[2] Most members of the genus are native to North America, but C. catostomus is also found in Russia.

In addition, in areas where backcross and hybridization were widespread, the scientists found offspring of recombinant hybrids with new ecological characteristics that made them more adapted to the local environment and even more competitive with native species.

Hybridization between different species of Catostomus fish occurs on a large scale, which means that many different environmental factors are involved in these geographic areas.

Although the hybrid forms of Catostomus fish break the common reproductive isolation between species, related research results can help to lead the protection of the waters where Catostomus fish live.
