The short movies above is not exactly what I saw, years ago, but the idea is similar. One thing I know is that most people think fish sauce is fish got rotten. That is not correct. I am not sure how to explain this, but during the procedure, if the fish got rotten, it turns bad and it will be stink and they are not successed, of course it will not become the sauce.
If you like to try, you might want cook (boil) it slightly. Adding some sugar and lemon/lime. It will taste a lot better. Some people like to add some water to lighten it.
