Scientific Name: Bryconamericus deuterodonoides Eigenmann, 1914

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2009
Date Assessed: 2007-03-01
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 commonness and sizeable distribution. Although parts of its range maybe under threat, this species is still likely to be stable.

Population [top]

Population:One of the most common species in the Orinoco basin. It is considered to be very common and widespread in the Venezuelan Llanos and piemont areas (Taphorn 1992).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:B. deuterodonoides is a benthopelagic (ecological region at the lowest level of water body) and potamodromous (migrating within fresh water only) species.
Movement patterns:Full Migrant

Threats [top]

Major Threat(s): There are no known major threats to this species. The Orinoco basin is one of the most intact river systems in the world with a relatively low population density (13 inhabitants per square kilometre), and very limited infrastructure development (World Wildlife Fund 2006). Lake Maracaibo, however, is heavily polluted and under habitat degradation but this area only constitutes a minor part of its range and is therefore not a major threat.

Conservation Actions [top]

Conservation Actions: There are no conservation measures in place, although the population trends are being monitored.
