A blackmouth is a catshark found from Iceland to the Mediterranean. It has bold blotches on its body. The blackmouth catshark is frequently caught in large numbers where bottom trawling and long-line fisheries take place, though most are thrown back, who knows in what condition. This is particularly the case in where there is trawling for deep water lobsters and prawns off Portugal and in the Mediterranean. Some are held back for human consumption, particularly following the decline in other deepwater shark species. This one is held to be at ‘least risk’ so is fair game. It may also be used for leather.
