Fishing in Guardians of Azuma

Post in progress:
Fishing has many different variables in every Rune Factory game, but I found this one more inconstant than others. Here are the factors:
First, Seasons. The four Villages are defined by the four seasons.
Weather: Some fish, like Taimen and objects like the Boot* appear to require rain.
Freshwater or Saltwater: This can be restricted to specific Seasonal Village locations simply because they have either a saltwater location or a freshwater one.
Quality of Fishing Rod
I am going to list the specific fish I caught at specific locations. Doing this after completion of Pescapedia so will not include earlier results unless I find verification in my journals.
Eastern Tri-Shell Island:
Boot*
(Is weather even a factor in the Sky? All I know is that every time I caught a about on Azuma, it was raining. On the sky island, no weather displays. It takes about 5 hours to fish out the area completely.

Abalone

Throbby Snapper

A smaller area, it can be fished out in a couple of hours. As you can see, I confirmed a Flounder catch here.
