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. The frequently improvised nature of the explosives used also means danger for the fishermen as well, with accidents and injuries. 

It is sickening nowadays to watch Dynamite fishing and shooting migratory birds widely spread in Lebanon, with no legal penalties. Check video on top.
