|Scientific Name:||Creagrutus britskii|
|Species Authority:||Vari & Harold, 2001|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Reis, R & Lima, F.|
|Reviewer(s):||Collen, B., Darwall, W., Ram, M. & Smith, K. (SRLI Freshwater Fish Evaluation Workshop)|
Assessed as Least Concern due to its fairly wide distribution. Damming that has occurred in the area of this species' distribution has not had a major impact on it.
|Range Description:||This species occurs in the upper Tocantins River basin in Brazil.|

|Population:||This species has a stable population trend at present.|
|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.|
|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:||The species occurs in at least one conservation unit (Terra Ronca State Park in northern Goiás).|
