Blast Fishing


Blast fishing a.k.a dynamite fishing is the practice of using explosives to stun or kill fish for easy collection. This often illegal practice can affect the surrounding ecosystem, as the explosion often destroys corals that often supports the fish.

Although outlawed this practice still occurs in the continent of Asia especially here in the Philippines. In the Philippines, where the practice has been well documented, blast fishing dates back to even before World War I, as this activity is mentioned by Ernst Jünger in his book Storm of Steel. One 1999 report estimated that some 70,000 fishermen (12% of the Philippines' total fishermen) engaged in the practice.

Extensive hard-to-patrol coastlines and corrupt government help make blast fishing a continuous challenge for the authorities.

Commercial dynamite or, more commonly, homemade bombs constructed using a glass bottle with layers of powdered potassium nitrate and pebbles or an ammonium nitrate and kerosene mixture are often employed. Such devices, though, may explode prematurely without warning, and have been known to injure or kill the person using them, or innocent bystanders.

The explosion creates an underwater shock wave that ruptures the fishes' swim bladders thus stunning them. A small number of fish will float to the surface, but most sink to the bottom. The explosion indiscriminately kill large number of marine creatures and also damages the coral reefs.

Such underwater shock is very bad and should be stopped to save the ecology and the environment.There is considerable marine life underwater and a food chain following it...why disturb nature?
