Going on bike touring and going to learn to fish, so I can stay in the woods and just eat fish and nuts for a few days
I'm going to get one of those 3m telescope poles
I will also stealth fishing

How do I know if theres fish in the lake?

How do I kill the fish quickest way? Should I just smash the head with a rock like old cavemen days?

I hate to smell like fish. Would using disposable rubber gloves be a good idea to avoid fish smell?

What knife should I use to gut it? Can I use my small buck knife that isnt super sharp?

Also how to I cook it over a fire?
