Surgical procedures in fish?

Hi friends.Its the first time I post here in a fish community, my place was always at the cat's one.
I never had a fish,and now I have 3 cats
But I 'd been reading a veterinarian magazine and there they relate many cases and procedures in different animals and one of those caught my atention
It was a fish disease - I dont remember the name,but is skin problem - and the procedure need was the surgical remotion of the stuff.
So I started wondering: HOW DO THEY DO A SURGERY IN A FISH? I mean,there are ways to keep him outside water for? How to measure his, well,vital signs or use anestetics?
Does anyboby here knows about? Links?
Thank you in advance.
