Freshwater fish some "other" guidelines:
1) Water temp below 52deg
2) Never raw anytime
3) For fresh taste use Lime juice min. 4hr. marinade
4) Most parasites are curable (if your Dr. is smart enough to find or look)
this alone should scare the stuffing out of you.
5) It's the bacteria you should really worry about, most harmful ones die
in cold water. Not all, so acidize them at the least
6) Enjoy the ones with NO BLEMISHES
7) Only use live fish
The medications for parasites are NOT pleasant, and your family and sex
partner might have to take them also. It's not just take a pill and it over,
it may last for months, with many secondary infections!!
