Might be so, I've never seen a 5 lb Jack crevalle. All I do know, a few years ago a bud invited us for a big fish fry, he was really excited to have a bunch over to share in his exploit. A scoop full of poot mud would have tasted better. Seriously like licking hot road tar. We asked what the F is this? He didn't know the name of the fish, but he had pictures. Yep, cleaning table full of smiling jacks. I dashed home and got a couple bags of speckled trout filets to save his outing.
I do know, I can filet a trout, red or flounder, and not do anything else but cook it up and eat it. You might can make a hardhead taste like a prime rib, I'll never know.
There is nothing you can do to make a Jack Crevalle edible to a normal human being. Clean it, prepare it and cook anyway you want, with any season or marinade and it’s still bad. Real bad. They don’t even cook it in Southern Louisiana where those Coon [censored] could cook an old tire and make it good. Anyone who likes eating it like would eat anything. People around the world eat just about anything. Jeffrey Dalhmer liked eating his guests. His mom said, “Jeffrey I don’t think I like your friends”. Jeffrey said “mom, try the vegetables.”
Pound for pound it will fight with about any fish in the bay or gulf. They will destroy a top water. I hate when we go fish the Chandelier Islands and within the first 5 casts of thr morning I hook a Jack or Bull red. He gets broke off, quick. No way I am fighting either of those while the trout are being hammered.
Skipjacks cut up make great redfish bait. Poor man’s Tarpon….lol.
