As far as keepin them shad alive there are 2 things I found to be a certain. Got to keep the water cool and circulating at a high rate, and do not try to use a live well with a corner in it. Have to have rounded sided. We used a cut in half 35 gal., white, food grade barrel. Added ice to it and used this tablet that turned the water blue......it added oxy to the water...just can't remember the name of the stuff right now, but we found out early on that a shad will swim into a corner and die for not getting enough flow through the gills. Ah, the striper fishing on Texoma and Buchannan.....good memories. Just hated getting up long before sunup and slinging a cast net for the shad around the lighted piers.
A gun in hand is a lot better than a cop on the phone.
