Albula esuncula 


Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Albuliformes Albulidae

Scientific Name: Albula esuncula
Species Authority: (Garman, 1899)
Common Name(s):
English Eastern Pacific Bonefish
Albula esunculus (Garman, 1899)
Atopichthys esunculus Garman, 1899
Taxonomic Notes: Frequently misidentified as Albula vulpes, an Atlantic species. It has also been previously identified as A. neoguinaica (a synonym of the Indo-central Pacific species A. forsteri). However, genetic data indicate the eastern Pacific form is a separate species (Colborn et al. 2001), for which A. esuncula is the oldest name. There is recent genetic evidence that this species may in fact represent two species: Albula esuncula from south of Mazatlan, Mexico, and a yet to be named Albula species from Southern California to Mazatlan (Pfeiler et al. 2008).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-05-01
Assessor(s): Nielsen, J.G., Monroe, T., Iwamoto, T., Harrison, I., Eschmeyer, W., Smith-Vaniz, B., Robertson, R., Collette, B., Tyler, J., Dominici-Arosemena, A.,Bussing, W., Lopez, M., Molina, H., Salas, E., Sierra, L. & Viquez, R.
Reviewer(s): Carpenter, K., Polidoro, B. & Livingstone, S. (Global Marine Species Assessment Team)
This species is widespread in the tropical eastern Pacific region. Although there is no population information available, there are no known threats that may contribute to population decline. More research is recommended as this species has recently been distinguished genetically from a Caribbean species. This species is listed as Least Concern.

Population [top]

Population:There is no population information available for this species. It is common in many parts of its range.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This demersal species inhabits estuaries, beaches, sand and gravel to depths of 10m. It is a carnivorous fish and its diet includes mobile benthic worms, crustaceans, gastropods and bivalves, and bony fishes.This species could be very widely spread oceanically due to the dispersal larval stage (leptocephalus). There is no appropriate life history information available for this species as it has recently been found to be genetically different from A. vulpes in the Atlantic.

Use and Trade [top]

Use and Trade: This species is fished for sport fishing and recreation. Also may be used for human food in some places.

Threats [top]

Major Threat(s): There are no known threats to this species. However, this species is caught in recreational fisheries (mostly catch and release).

Conservation Actions [top]

Conservation Actions: There are no known conservation measures for this species. However, this species' distribution includes a number of Marine Protected Areas in the tropical eastern Pacific region.

Research is required to determine the extend of the range of this species as it is has recently been shown to be a separate species from a Caribbean species. Also, more research is needed on its population status, and the impact of recreational fishing activities.
