I’d read before that pickling fish kills bacteria. I guess vinegar kills anything.
No one and I mean no one has ever gotten sick from pickled or fermented (pickle/kraut like fermentation) food. I exclude badly butchered Fugu, Death Caps and other will kill yous from the category.

It is delicious. Cod works fine here in the US. Dont pay for the Sea Bass. Not worth it. Can gaurandamnedtee you wont get sick from it. (My salivary glands are in overdrive just with me typing about it)
I occasionally put chopped raw oysters in my homemade kimchi.
They add to the cabbage in a way fish sauce and fermented brine shrimp can’t.
Good stuff!
