Human pressure: since populations are doing so poorly, the Smalltooth sawfish are unlikely to be intentionally targeted since the catch per unit effort would be so low. The sawfish can still be unintentionally captured as it becomes easily entangled with its long rostrum. The animal has historically been targeted for this valuable body part and sometimes its fins as well.
