my buddy and i recently bought a bait tank. we used to put shad in the live well and when they died we put them on ice to keep them fresh. i read an article a guide wrote that he did a study (unscientific) where he put on cut shad that had been on ice on rods and fresh cut shad on rods and he found that the fresh shad got bites like 3x more than the shad that had been on ice. he said that once the shad had been dead over two hours the bite went down significantly. no, he wasn't selling anything either. we have had great success keeping them alive but its been cold. i know when the weather heats up it will start being more difficult. i read where you need to put salt in the water and that helps keep them from getting red nose and keeps them alive. i really dont want to put salt water in my boat for obvious reasons. would like some tips from anyone that uses bait tanks what you add to your water. it would also help if it was economical. i know to change the water and keep it cool. thanks.
