Fishing is a sport that captures all the excitement of floating around on a stagnant body of water and holding a stick, which may explain why no one buys tickets to watch it. For the more criminally reckless outdoorsman, however, fishing can become a heroic display of technology and ingenuity triumphing over nature--a phrase which here means "blowing fish up with dynamite".
Utilizing traditional explosives and/or homemade bombs made from artificial fertilizer, blast fishermen locate schools of fish congregating at coral reefs and start lobbing down hellfire like Dresden. The resulting shockwaves either kill the fish outright or temporarily stun them, allowing the fishermen to literally scoop them out of the water by the bucketload.
"Boy, they're really biting today."
Although the practice is illegal the world over (but why?!), it's quite common in certain areas such as Southeast Asia and Africa, and on virtually every backwoods fishing trip where alcohol is involved.
