Chance of catching trash and algae

[Kusocheck]

Hello! I was able to fill the ponds with different types of fish on my farm map. I added individual fish to the river, but now I want to add algae and trash. By default, what is the chance of algae and trash dropping when fishing in normal rivers, lakes, ponds and sea? Where can I find this information?

On the wiki for the given zone. Best trash source is level 100 of the mines and then usually small pond on the farm. Algae drop a lot from level 20 mines fishing, some at 60.

I didn't find any information on the wiki. :(
It's not because I want trash. I just want balance. My ponds only catch fish, but I want trash to be caught, like in regular ponds.
