Brycon posadae 


Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Characiformes Bryconidae

Scientific Name: Brycon posadae
Species Authority: Fowler, 1945
Taxonomic Notes: Transandean Brycon species need a taxonomical revision. Also, much of the Colombian Pacific versant (mountain slope) is inaccessible for Colombian ichthyologists, so little is known about the fish fauna inhabiting the area.

Assessment Information [top]

Red List Category & Criteria: Data Deficient 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)
Very little is known about the species. The species could potentially be threatened but the area in which it is distributed is so inaccessible that no inferences can be made. Coupled with its cryptic habits, it is difficult to infer anything about the species, so it is assessed as Data Deficient.

Geographic Range [top]

Range Description: This species occurs in the Trans-Andean river basins of Ecuador and Colombia. The species is very poorly known. Lack of records reflect lack of collection and difficulties in collecting rather than rarity.

Habitat and Ecology [top]

Habitat and Ecology: B. posadae is a benthopelagic (ecological region at the lowest level of water body) species. Plant material is an important part of the diet of adult Brycon species; and thus these fish play a role in the dispersal of plants whose fruits they eat (Berra 2001).
Systems: Freshwater

Threats [top]

Major Threat(s): Due to their dependence on plant material in their diet, the destruction of rainforests surrounding their habitat could have serious consequences for this species. The areas that the species occurs in are unlikely to be particularly heavily impacted.

Conservation Actions [top]

Conservation Actions: There are no conservation measures in place and research into general biology and ecology (habitat status and population trends) are required.
