As Conta Kinta said "That is u need lots". I use a plastic container with water softener salt liberally thrown over the bait where it will turn into a slurry. I use this method when I go away for a week or more and when I know I'm not going to have any refrigeration or ice. I've left them in the brime for over a week without any loss of quality. The salt preserves it as well. Cockles turn into little leather patches but they still work.CheersJim
