What about fly-fishing?
What about fly fishing? - There is no more exiting fly fishing quarry than the wild and brutish peacock bass. This is where subtlety and finesse meets sheer physical power—a true test of tackle and techniques. Acute Angling operates in some of the Amazon’s best fly fisheries. Here are some general guidelines:
Patterns -Extra-large streamers fished on a sinking line are most productive (not only for overall numbers, but for larger-sized fish as well). We highly recommend “Sidewinder's Peacock Rattle Fly in red/yellow”.
Other popular streamers include 6-inch (5/0) bi- colored bucktails in red/yellow, olive/ white and red/white. Big Deceivers, Bunnies, Saltwater Zonkers, Clousser Minnows and other flashy baitfish imitations will also take fish. All patterns should have generous amounts of matching Flashabou or Crystal Flash. Although big saltwater poppers are exciting to fish, they can be extremely exhausting to cast and retrieve while not terribly effective at coaxing bigger fish to the surface.
Fly rods should be fast action models to load sinking lines more efficiently and provide needed 'backbone'. Bring at least two, because rods can break under the ‘jungle stress’. Reels don't need to hold a lot of backing since peacocks don't make long runs, but a smooth, strong drag is essential. Recommended 'heavy' fly rod & reel combinations for sinking line: A stiff/fast action, 9-foot, nine -weight rod (Sage 990-3RPLX or G. Loomis FR1089-4) with Scientific Anglers 'System 2 -89'. Recommended 'medium' fly rod & reel combination (for floating lines): A stiff/fast action, 9-foot, seven or eight-weight rod and matched reel.
Sinking lines are much more effective for streamers than floating lines. Don't bring just any old sink tip. An integrated sinking line such as a Rio 24-foot 300- grain Density Compensated line is easier to cast and can be fished on anything from an 8 to 10 weight rod. If you like, also bring a floating line with a drastic weight-forward taper for poppers and sliders but be aware that big fish are more readily caught on sinking lines.
Leaders: Peacocks are not leader shy. Most fly anglers use a straight shot (approximately six feet) of flexible 50 pound monofilament leader. Anything lighter can be snapped off like sewing thread if that fifteen 'pounder' runs you into a wood pile. You will go through a lot of leader material, because of the peacock's abrasive teeth. We recommend buying a package of soft monofilament leader material (we like Jinkai). If you're trying for an IGFA record, you'll have to follow their leader specifications, of course.
Suggestions - Although we provide spinning and baitcasting rods and reels, we do not provide fly fishing gear. You must bring your own. Fly fishing for peacocks is very productive, but can be tiring if you're not used to blind casting and rapidly stripping a heavy-weight fly rod all day long. We strongly recommend that you consider switching off to baitcasting or spinning tackle from time to time to give yourself a break. We have conventional tackle readily available for your use.
Under the right conditions, and on the right rivers, fly fishing can be the most effective of peacock bass techniques. The key point to keep in mind, however, is that proper conditions and locales are necessary for success and not all regions and seasons are equal. If you wish to concentrate on the fly, you should be careful to choose fisheries with the right water types and conditions. With the right planning, peacock bass can be the greatest fish you've ever experienced on your fly rod.
