Eat 3 stamina foods and will catch almost every fish in 20m range

Keep your line distance at 10-14. I think the food you spend keeping your stamina up is not worth the food you catch.

I find making shorter cast helps a lot, hook'em at 10m or less and you'll reel them in every time I have found.

Two stamina food and short casts.
You want to see the fish as it approaches the hook and time the pull for easiest catch so being close helps.

Easiest to do while in a boat so youre out close to the fish. Another trick from the shore to walk (not run) backwards while reeling, once they hit dry land just pick em up

maybe its the stam issue

There is also a timing component. There is a ripple in the water, but eventually you learn to use intuition,

Yeah, fishing is easy if you can see the fish underwater. It's really obvious when the fish is about to bite so you just need to time your RMB click-hold with that.

Another way is passive fishing or trolling. When you're getting headwind during your boat trips, just cast the line and sail at speed 1. Might as well catch some fish if you can only move that fast. If you're sailing along the shoreline, you can easily catch pike and tuna this way.
