The alternatives are already known, some of which have been in use for hundreds of years. Tocopherol's are basically Vitamin E and are on the Coast Guard approved list of preservatives that can be used to preserve fish meals. Just a properly prepared and dried food, absent any preservatives, will provide a shelf life up to a year. Natural preservatives, such as mixed-tocopherol's, can add a year or more onto that.
What you will not achieve, absent the artificial preservatives, is the almost indefinite shelf life.
F1 Vet, dude, you've defined your argument perfectly well. The risks are acceptable to you, they are just fish. Cool. I can buy that. I, on the other hand, hope for better.
