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 because of the lack of threats acting on this species. It does have a restricted range in an area with heavy pollution and habitat degradation. Therefore monitoring of this species should take place.

Habitat and Ecology [top]

Habitat and Ecology:C. maracaiboensis is a benthopelagic (ecological region at the lowest level of water body) species. Prefers relatively fast flowing waters, feeding on benthic invertebrates from the bottom. Occurs in small to medium sized streams, but not rivers.

Threats [top]

Major Threat(s): Due to the small nature of the streams in which the species occurs, it is likely that a good proportion of habitat remains intact enough to support this species. Even considering the extent of disturbance in the Lake Maraciabo basin, the species is likely not to have suffered unduly. Creagrutus species are relatively resilient to habitat modification.

Conservation Actions [top]

Conservation Actions: There are no conservation measures in place and research into the population trends is required.
