Blast fishing or dynamite fishing is the practice of using explosives to stun or kill schools of fish for easy collection. This often illegal practice can be extremely destructive to the surrounding ecosystem, as the explosion often destroys the underlying habitat that supports the fish.
In the Philippines, dynamite fishing decimates entire ocean food chains and the corals where the fish nest and grow. Blast fishing kills the entire food chain, including plankton, fish both large and small, and the juveniles that do not grow old enough to spawn. Without healthy corals, the ecosystem and the fish that live within it begin to die off.
