Habitat and Ecology [top]

Habitat and Ecology:C. britskii is a benthopelagic (ecological region at the lowest level of water body) species. Occurs in moderate sized tributaries, generally bottom swimmers feeding on benthic aquatic insects. Swim in small schools in fast flowing water.

Threats [top]

Major Threat(s): Damming is in fact a factor of major concern in regard to the conservation of the ichthyofauna of the upper Rio Tocantins area. Within the range of C. britskii the huge Serra da Mesa dam was built, which undoubtedly destroyed much habitat formerly occupied by the species. However, since C. britskii is a small-sized species which occurs in moderate-sized streams, only the building of large dams would not probably result in its demise.

Conservation Actions [top]

Conservation Actions: The species occurs in at least one conservation unit (Terra Ronca State Park in northern Goiás).
