In the winter on the James river do the Gizzard Shad die from the cold water temps? Or do they migrate down river? Do the shad live for more than one year? Can you catch shad in Jan. or Feb. in the Hopewell area?Im wondering If I go down there if I need to bring bait in Jan. or Feb. Anybody heard anything about gillnets for next year?I have not heard much on this subject.
