I am looking for an approved and tested recipe for canning crappie? I
buy canned smoked trout in canola oil which is great and actually better
than so I figure crappie would work as well. It's hard to find recipes since most
commercial companies obviously keep their recipes secret. I was planning on a 4
hour salt and sugar brine (1 cup salt, 3 cups brown sugar and 8 cups water) since
that is what I do for salmon (photo attached) but not sure if I would have to
add oil to the crappie since it's a lean fish?

Also I read that you would need to freeze the
fish first to kill any parasites but wouldn't the pressure canning process kill
any parasites or bacteria in the fresh water fish and anyway I read that you
have to freeze fish to -4 for 7 day which I don't think my freezer will go that
low?
