With all this artic weather upon the south, I am concerned about something. I remember we had cold weather like this few years ago and it killed a bunch of fish @ the coast where I fish @ (Savannah area). Mostly trout, drum, flounder, etc. I was wondering if this big chill down will have any effect on these fish and the over wintering shrimp too. Does it have to be brlow freezing for a while for this to happen or can it be a few cold nites process?
