Blast-fishing refers to the use of explosives to kill or stun fish, for food. It is also commonly referred to as ‘bomb-fishing’ or ‘dynamite fishing’ – in fact dynamite is a particular type of explosive that is not in fact the kind used in blast-fishing in Tanzania. Globally, blast-fishing has mostly been prevalent in south-east Asia, notably Philippines, Indonesia and Malaysia. In the western Indian Ocean the only country where the practice has ever significantly taken root is Tanzania.
