Description The Indian Sharpnose Ray (Telatrygon crozieri) is a small (to 40 cm disc width) ray occurring in the
northern Indian Ocean, in India and Bangladesh, and possibly Pakistan. It is demersal on the inner
continental shelf from the surface down to a depth of 50 m. It is captured in shrimp trawl and gillnets
and rays tend to be targeted by industrial and artisanal fleets. Species-specific data remain limited due
to species misidentifications and recent taxonomic changes. Declines in batoids from intense and
increasing fishing has been reported for India, Bangladesh, and Pakistan. This species has not been
recorded recently on the west coast of India in regular trawl surveys and this historically widely
distributed species now has a much narrower distribution. Even on the east coast (Tamil Nadu to West
Bengal) of India, few individuals have been encountered and this number has declined during
2010–2018 surveys and the Indian Sharpnose Ray is now only regularly observed in the east coast from
Odisha to West Bengal. The entire geographic range of the species is subject to intense and increasing
fishing pressure with little refuge at depth. The steep decline in landings of batoids in India, Bangladesh,
and Pakistan is consistent with a population reduction of 54–84% over three generation lengths (26
years).
