Grizzly-sized Catfish Caught in Thailand
An anonymous reader writes "Fishermen in northern Thailand have netted a fish as big as a grizzly bear, a 646-pound Mekong giant catfish, the heaviest recorded since Thai officials started keeping records in 1981. The behemoth was caught in the Mekong River and may be the largest freshwater fish ever found."
even Mark Twain claims to have seen one more than six feet long and weighing 250 pounds in the Mississippi River. (How he managed to weigh it is not recorded ^_-).
If you're really skeptical, visit the natural history museum at the University of Kansas to see skeletons and pictures of catfish taken (by hand by divers) in the Kansas River just a hundred years ago.
Unfortunately, in the more unregulated fishing areas in the World, explosive, and cyanide fishing is still popular.
The premise behind explosive fishing is to lob down a couple of sticks of your favourite explosive, and then wait for the stunned fish to float to the surface before scooping them into your boat. Unfortunately, it is extremely indiscriminate, can damage the remaining fish, and can cause extensive underwater damage to the seafloor.
Cyanide fishing is just as bad, where divers puff a small amount of cyanide into the water to stun fish before collection. This keeps the fish live, and results in no external physical damage. On a broader scale, mass poison release for wider area fishing is less effective, but just as dangerous to sealife. The other problem is that fish collect toxins in their bodies which then get passed through the food chain, to us.
If you wondered how they got the live fish into the tank at some Asian restaurants, it could very well be the result of cyanide fishing, especially if they are claiming them to be wild fish.InfoSec that matters, when it counts.
