Plankton,
I would use a small hook, baited with shrimp or squid. It is the easiest way to catch a fish. Try using a barbless hook or if you can't find a tiny barbless hook, you can simply cut off the barb. If the hook is too large, then try a fly fishing lure. I caught all my fish within minutes. It's real easy to do and doesn't harm the fish too much. The lip heals in no time. Hth.
