I saw a show on TV a couple of years ago when a couple of bass fishermen went there to catch Peacocks.
When they met their native guide and were loading gear into his pram, the guide had a pretty animated discussion with their interpretor, who relayed the message that if they were planning on using their bass gear, they shouldn't plan on landing anything.
These guys had the usual heavy duty pool cues, 20# braided line, and high torque, low retrieve ratio reels. They laughed and decided to show the natives how Americans catch bass.
They used topwater plugs...after five or six casts one of the dudes gets a hit that almost rips the rod out of his hand and breaks the 20# before he can yell "Son!".
Five more minutes, three more hookups, two more busted lines and a busted hook, and the fellas accepted the guide's gear, which consisted of super-heavy-duty boat rods, roller guides, and big, big, Penn big game reels, with 50# braided line.
They still only landed about half the fish they hooked.
They did, however, hook a lot, and they hooked them on damn near everything...plastic worms, buzz baits, spinnerbaits, and plugs. The Peacocks didn't seem to care, as long as it was moving they'd hit it.
Pirahna's, on the other hand, I believe are usually pursued using small hooks, steel leaders, and bait. They have pretty small mouths, and contrary to popular belief, aren't particularly aggressive. They're not very big, either, so probably wouldn't require very heavy gear.
BTW, the Peacocks looked to be anywhere from eight or ten pounds to well over twenty, and the only resemblence to largemouth bass was body shape. They have big teeth, too, hit and jump like tarpon, and make really fast runs, usually right into trees in the water.
I'd love to give it a try sometime...post results of your buddy's trip, expecially pix if you can get 'em.
Fish on...
Todd.
