I'm not trying to be facetious here. But, maybe they are already full? I know some parts of the sound are loaded with bait right now. Are their bellies packed when you open them up? It seems to me that a fish with a full gut entering fresh water would get lock-jaw.

But then, that raises the question of fish hunger. Are they more inclined to bite when their bellies are empty or when some mysterious instinct triggers a feeding reflex? I'm sure everyone here has caught plenty of fish that were so jam-packed with bait that it was stuck in their throat cuz there was no room for it to go down......go figure.
