Threats
The main threat to this species is incidental capture in trawl and gillnet fisheries. Marine habitats in the Gulf are experiencing high levels of disturbance and quickly deteriorating due to major impacts from development activities (including dredging and reclamation), desalination plants, industrial activities, habitat destruction through the removal of shallow productive areas and major shipping lanes which is likely to impact this species.
