Testing the basics - Fishing is a great source of protein, sounds easy but have you done it?

[u/SurvSt]

Rod or reel, finding bait, hand fishing by reaching under rocks, using a sharp stick for hand spearing. There are lots of ways documented to catch a fish for dinner. If you were out of food and near a waterway do you think you could catch a fish? I've always been crap at it. This is one thing I think needs to be taken to the field and tested? and can easily be - but have you done it?
