They stink.
I caught a 2 footer yesterday, caught and released.
That is a beautiful fish...very good picture. The first fish (grouper) I ever speared was on my scuba checkout dive trip in the Bahamas, 1971. It wasn't huge (maybe 15 lbs) but I remember that it gave me a bit of a ride before the little rodeo was over.
Re: your picture...how deep were you and what camera did you use to take the Jewfish shot? The lighting and resolution look good.
