Its a bit dry unlike tuna. Add some olive oil or mayonnaise would work but I never tried it. Since its home canned I am a bit nervous to eat it without some cooking first due to botulism.

Assuming it's pressure canned at the right time and pressure, it's safe to eat from the can. The old warnings about boiling it first was from a time when people were still regularly water bathing things like meats and veggies.

Cooter you never can sucker's up that way? Old moonshiner i use to run around with would wade creeks every spring with a single shot .22 rifle and flash light, lol. He shot sucker's when they were spawning and canned them in mason jars. Made patty's out of them and fried in skillet, was pretty good eating.
