31. Roughnose Stingray

Pastinachus solocirostris

About

The roughnose stingray is a small species of ray found only off the coast of Malaysian Borneo and Indonesia, named after the unusually rough texture of its snout. It lives in mangrove estuaries and turbid coastal habitats.

Almost nothing is known about the biology of the roughnose stingray.

The main threats to the species are habitat destruction and degradation. Mangroves in Indonesia and Malaysia are rapidly being lost due to aquaculture, urban development, logging and conversion of land for agricultural use. Furthermore, the mangroves are being degraded by pollution and destructive fishing practices. Indonesia and Malaysia have lost an estimated 30% of their mangrove habitats since 1980.

Fisheries also pose a major threat to this species as they are extensively fished throughout their range. They are caught by longline fisheries, bottom trawlers and demersal gillnet fisheries operating off the coast of Kalimantan (Indonesia).

There is currently no legislation in place to protect this species. According to the IUCN, monitoring of the population is essential in order to determine the population trend.
