If anyone wants to know my secret, here it is.
You have to get up early, real early. Go to SP town and get some coffee.
Go to the back bay docks. Grab a Belikin on the way, 2 if your going to fish a while.
Catch a good fisherman. Normally they are coming around about then or will be @ the cleaning station.
I prefer to fish with BZ $50's, but you can use US$ 20's.
The fish come right out cleaned and ready to cook.
Now that's fishing!
