Title is pretty self-explanatory. I regularly eat high liver, however i have never heard of anyone making "high fish" by just putting some fish in a jar and letting it sit.

To expand a bit, ive been fishing almost every day for the past couple weeks (underwater, not with a rod) and i eat most of what i catch and the rest i give to the cats.
Today while fishing i had the thought of why not trying to do something else with the fish. I have seen stuff like this https://www.wikihow.com/Ferment-Fish but it just seems unnecessary, thats why im asking if any of you have any experience with making 'fermented' fish in the classical way we know of just leaving meat in a jar.

It would definitely be worth investigating that (not the kind of thing i study though). I enjoy specially high liver and agree with its benefits, having experienced them myself. It's true that people should know about this kind of stuff for their own benefit, but thats not the direction medicine is/has been taking... its not about health, its about keeping you drugged and squeezing you out of your money.

Welcome.

Are you interested in researching High Meat? Sometimes I think that high meat as a cure for depression would be the only thing powerful enough to cause a paradigm shift in modern medicine (to raw meat/food).
