Blast or Dynamite Fishing
In this technique, explosives are set off under water to stun or kill schools of fish after which they are simply scooped up in nets and brought to the surface. Although commercial dynamite is sometimes used, in Indonesia blast fishers commonly construct homemade bombs using glass or plastic bottles filled with artificial fertilizers such as potassium nitrate or ammonium nitrate, often mixed with pebbles an kerosene. The explosives completely destroy the underwater environment, leaving it as rubble. Dynamite fishing has contributed to massive destruction of Southeast Asian coral reefs and others world wide over the past 20 years.
