I haven't yet figured out what happens when you use, say two of the fish types with weight 1 and the third one, is, say weight 5. Do I only get the amount of fish that I would get with 3 weight 1 fish?

It seems like you get a decent amount of fish, so maybe it adds all the numbers together to determine how many you get?

You dont need to combine them to cut up the fish.
The numbers tells you how good they are, like 1 means they are not very good, and 5 means you get more cut fish when you cut them up.

I am playing my first map after the Mistlands update. I was running along the shore when a fish came flying by my head. Are fish supposed to jump out of the water? I've collected 2 sizeable fish this way.

They use to do it more, so they tuned it down a bit, but some what yes.
