Conservation status

Primary threats

The Greenback Stingaree is listed as Vulnerable by the IUCN. The Greenback Stingaree faces significant threats primarily from being caught as bycatch in otter trawlers and Danish seiners operating in the Southern and Eastern Scalefish and Shark Fishery (SESSF). Despite lacking commercial value, it is often discarded when caught, and its reproductive output may be affected by post-capture handling.
