In Indonesia, food fish and aquarium fish are caught using the poison sodium cyanide. Sometimes the poison is shot directly at the target fish to stun them and make them easier to catch alive. Other times, entire 55-gallon drums of cyanide are dumped onto the reefs, turning them into aquatic graveyards, as the chemical kills living coral, invertebrates and non-target fish.
Dynamite is also used for fishing in this country. Fishers blast reefs with dynamite or other explosives that rupture fishes' air bladders, so they can scoop them up as they float to the surface. The explosions destroy reef formations, kill non-target fish (by-catch) and often kill or maim the fishers themselves.
