Dave,
Not exactly but I see a lot of additives for bait in the Aquatic Ecosystems catalog such as "Tranquil," "Better Bait," "Finer Shiner" etc. When I haul trout and perch I use a product called "Sure Haul" that reduces stress, accumulation of ammonia, nitrate, and prevents foam up, which I add uniodized salt to. I haven't lot a fish yet in the hauling tank and I've hauled for up to 13 hours.
