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.
