Now, as we all know, fish both regen faster, and get used up faster.
However, how about a way to tell how "good", high Q, or just how many fish are left in it?
Idea 1: The frequency the fish jump out of the water. The more fish/higher Q/more stocked the node is, the faster the "Fish jumping out of the water" plays.
Idea 2: The number of fish in the actual animation.
Just put all your ideas about fishing in here, I guess.
