All the abstaining from blood in the OT is a kind of preparatory fast...

And "Don't eat fish on Friday" is a prep for WHAT?

Fasting from fish on Friday was, at one time, a required penitential practice in canon law --- not a preparation for anything.

It's now listed, in the present canon law, as an optional discipline, but one which is very much recommended. I have to confess my weakness here, because I rarely observe this abstinence. But what you're dealing with here, is a person who is not a very good Catholic.
