I may be in the ball park if not exactly what you requested. I was stationed in Panama for three years and caught tons of peacock bass in Lake Gatun. Mostly using live bait and some lures (mostly crank baits). Peacock are much more aggressive than our largemouth variety and they are easy to catch (at least in Gatun). I sometimes used a minnow spreader and often caught double headers from a boat. I didn't find peacock fishing especially challenging. I mean the bigger the bait, the bigger the fish and they hit almost anything. I don't think I'd spend money to fish for them.
I would spend money to fish once more on the Hannibal Bank off Panama. Mahi, tuna, marlin, wahoo...awesome.
But go where you want. I don't know everything.
apologies for hitting a dead thread. need more cofferr
