Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA CHONDRICHTHYES RAJIFORMES UROTRYGONIDAE

Scientific Name: Urobatis jamaicensis
Species Authority: (Cuvier, 1816)
Common Name(s):
English Yellow Stingray
Synonym(s):
Urolophus jamaicensis (Cuvier, 1816)
Taxonomic Notes: The species was originally placed in the genus Urolophus, but was later moved by Garman (1913) into his newly erected genus Urobatis, which included all eastern Pacific and western North Atlantic round stingrays. The genus Urolophus is restricted to the stingarees found in the Indo-West Pacific. Both genera are frequently seen in the literature for western North Atlantic forms, but current research suggests that Urobatis is the correct genus (Ebert 2003). Urobatis is sometimes placed in the family Urolophidae, however this placement is incorrect and the family Urotrygonidae is valid (McEachran et al. 1996).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2006
Date Assessed: 2006-01-31
Assessor(s): Piercy, A.N., Snelson Jr., F.F. & Grubbs, R.D.
Reviewer(s): Kyne, P.M., Fowler, S.L., Compagno, L.J.V. & Cavanagh, R.D. (Shark Red List Authority)
Justification:
A small (to 36 cm disc width) nearshore batoid of coastal zones, bays and estuaries with a wide distribution in the Western Atlantic from North Carolina around Florida into and throughout the Gulf of Mexico and throughout the Caribbean (including the Antilles), Central America and the northern coast of South America. It is common in parts of its range including the Florida Keys and areas of the Antilles. Bears litters of 2 to 5 pups and shallow coastal lagoons and seagrass beds are important for parturition. The yellow stingray is not targeted by commercial fisheries, but is likely taken as bycatch in nearshore fisheries throughout its range. However, it is collected for the marine aquarium trade and the extent of this harvesting requires examination. Although no catch information is available, the species is assessed as Least Concern given its wide-range, common occurrence in some areas and small size (and thus relatively productive biology). However, the continued vitality of the species will be reliant on healthy seagrass habitats, which are important for parturition.

Population [top]

Population: This ray is common in the Florida Keys (Snelson, pers. obs.) and parts of the Antilles but in not thought to be abundant in most of its range (Bigelow and Schroeder 1953). It is reported that Terminos Lagoon, Bahía de Campeche, Mexico is a breeding and nursery area (Yáñez-Aranciba and Amezcua-Linares 1979).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Habitats include bays and estuaries and low-energy surf zones, especially in hard, live-bottom insular habitats, also sandy, muddy and grassy bottoms (McEachran and Fechhelm 1998, McEachran and Carvalho 2002, Snelson pers. obs.). Reported in a salinity range of 26 to 40 ppt in Mexico (Castro-Aguirre and Perez 1996). Parturition takes place in seagrass beds (Thallassis testudinum) June through August in the Bahamas (Grubbs unpublished data). Aplacental viviparous with litters of 2 to 5 (McEachran and Fechhelm 1998, Yáñez-Aranciba and Amezcua-Linares 1979).

Threats [top]

Major Threat(s): The yellow stingray is not targeted by commercial fisheries, but is likely taken as bycatch in nearshore fisheries throughout its range. Inshore fishing in some parts of its southern range may be intensive, but the extent of bycatch of this species is not known. It is, however, targeted for the aquarium trade. The extent of this fishery requires examination. Given their inshore occurrence, habitat loss may become an issue in the future for this species. This issue will become particularly relevant if seagrass habitats became degraded or lost, due to their importance for parturition.

Conservation Actions [top]

Conservation Actions: None in place at present. The extent of the trade in this species for the aquarium requires examination.

The development and implementation of management plans (national and/or regional e.g. under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) are required to facilitate the conservation and sustainable management of all chondrichthyan species in the region. See Anon. (2004) for an update of progress made by nations in the range of U. jamaicensis.
