Loss of habitat and fishing
The main threats to the sawfish which is actually a type of ray are habitat loss and entanglement of their saws in fishing nets.
Their fins are also among the most valuable in the global shark fin trade as a celebratory dish in some Asian cultures.
Furthermore sawfish s nose are often sold as curios or medicine.
One of the study s authors told Simon Frasier University that complete extinction of the sawfish was possible if nothing was done to curb overfishing and to protect its threatened habitats. Through the plight of sawfish, we are documenting the first cases of a wide-ranging marine fish being driven to local extinction by overfishing, said Nicholas Dulvy.

Sawfish have disappeared from half of the world’s coastal waters and the distinctive shark-like rays face complete extinction due to overfishing, according to a new study by Simon Fraser University researchers, published in
Science Advances.
Sawfish, named after their unique long, narrow noses lined by teeth, called rostra, that resemble a sawblade, were once found along the coastlines of 90 countries but they are now among the world’s most threatened family of marine fishes, presumed extinct from 46 of those nations. There are 18 countries where at least one species of sawfish is missing, and 28 more where two species have disappeared.
