Question on Herring (Alewives)

[go_fish]

When I go fishing at Waywayanda or Aeroflex and drop a live herring to the bottom in about 50 to 60 foot of water, the herring comes back dead. Well, at least in my experience. It is about 41 degrees at that depth (right now). Why does the herring die? Not enough oxygen down there, too cold? Since the herring cannot survive that deep does that mean there are no other fish down there?
