I was living outside of Paquera, CR for a while, spending all my free time trolling for Rooster. I have had great success with free-lining live bait out near the rocks. But my question is, what is this baitfish? You can catch them with ease off any structure with fish scraps and a small hook, and the Rooster love them (maybe not as much as lisa).
They look exactly like Blue Runner, which I saw all the time growing up in the Atlantic, but from the sources I have checked state they're not found in the Pacific? Maybe a Pacific species? The locals call them Bonita, which doesn't make sense to me.
