Species Name

Pale-edge Sharpnose Ray

Scientific Name

Telatrygon zugei (müller & henle, 1841)

Family Name

Dasyatidae

IUCN Status

Vulnerable

Last et al. (2016a) revised the family Dasyatidae, erecting the morphologically conservative genus Telatrygon and moving zugei across to this new genus. Telatrygon crozieri from the northern Indian Ocean is considered distinct from T. zugei (which occurs in the western Pacific).

Biology

Length: It reaches a maximum size of ~29 cm disc width (DW) (~80 cm total length), male and female size-at-maturity is unknown. Size-at-birth of ~8 cm DW.  

Gestation Period: Unknown

Litter Size: 1-3

Life Expectancy: Generation length of 8.5 years.

Diet: Feed on bottom-dwelling organisms; primarily small crustaceans, but also small fishes.

Habitat and distribution

Habitat: The Pale-edge Sharpnose Stingray is demersal on the continental shelf.

Distribution: The Pale-edge Sharpnose Stingray is endemic to the Northwest and Western Central Pacific from southern Japan to Viet Nam, including China and Taiwan; the presence of the species in Thailand and the Philippines is uncertain.

Depth: 0-100 m

Landing sites: Machilipatnam, Nizampatnam, Vodarevu, Pakala, Okha, Porbandar, Mangrol, Veraval, Diu, Digha Mohana, Royapuram Fishing Harbour, Cuddalore Fishing Harbour, Nagapattinam Fishing Harbour

Commercial Value

This species is used for human consumption and possibly fish meal. In China, this species is preferred for consumption, as it is small with good quality flesh.

Threats

The Pale-edge Sharpnose Stingray is subject to fishing pressure across its spatial and depth range. It is taken as bycatch in industrial and artisanal fisheries with multiple fishing gears, including trawl, set net, and gillnet, and retained for human consumption and possibly fish meal.
