There are oxygen systems out there that will do the trick. Be carefull though as I think these possesion limits are still in force...http://www.matagordabay.com/hodgesaeration/
Hickory Shad / American Shad
American shad and hickory shad populations are currently listed as unknown, but a complete stock assessment is expected in 2007. American shad populations are believed to be suffering from depletion due to habitat loss and pollution.
• ME, NH: 2 fish any size
• MA, CT, RI: 6 fish any size (any combination of both species)
As was mentioned earlier,don't handle them except by the head.Anywhere else and every scale you touch,will fall off,fouling the water,and your systems filters.
A few things I do to keep them lively:
Don't touch them until you want to use them as bait. Remove from darts with pliers only. Get them in the tank ASAP.
Get them as much oxygen in the tank as possible. Aerated rock from a pet store and an air compressor. Total cost $25.
