Snagging them in the mouth is still snagging them, even if it's productive...at least if they are suspended below a float and you don't rip it around it should be an actual bite when the float goes down.

Hatchery fish or not, I just can't abide a fishery where the main technique is to floss them...it takes the fair chase out of the equation, and without that you may as well be using a gillnet, in my opinion.

Your mileage may vary.

Fish on...
