The last few times fishing (off Playa Miramar) I've come across several grouper just kinda floating in the water, flapping their fins and swimming away in short bursts if you approach/grab them. A few have washed up on shore too, all very much alive but unable to do much swimming. We'd been catching and releasing grouper during this time, but all the fish released seemed to dart off pretty quick and we were only in 20-40 feet of water. Panguero activity is fairly common is this area, but I'm unsure if that has anything to do with is. I'm sure with all the experience of those on this forum that somebody has seen this before and can help explain.
