I think that sometimes when they don't bite it's because there is so darn much food and their stomach is stuffed. The one I caught was like that and there were bait fish everywhere on the humminbird where I caught it.
I did see a ton of baitfish but these were on the top o the water. You are right mermentau. But there is this fella. JR. ya may have seen his posts. He can catch a sacalait thanksgiving afternoon AFTER they had dessert
