Bushcraft fishing is not to use rod to my mind. One good way of cathing fish easily and efectively is to do like this:
You need a river!
You need a looooong stick... Like 9 feet ir so.
All you need from home is some line and small hooks.
Catch some bugs or grasshoppers.
The way you do this is very simple AND effective! The stick you prepared should be long enough to reach out at least a meter into river. You stick it in a ground on about 60 percent angle, line should be just long enough to reach water. You put your bait on hook. The secret is here: your setup should work in a way, that you would not need to stay there fishing. Good stick and line length combination should give the effect of bait being on the very suface of water and moving with current, then springing back again, landing, floating, springing, landing, floating, springing................ What are the advantages of this technique? If you get it right it needs less stuff even than hobo fishing, it's definetly MORE effective as you leave it to be and BIG fish comes to investigate. Is it legal????? God knows people, to me it's the same as leaving your rod on the bank of a river.... Buts it is the best way to catch all kind of white fish, trout and so on without all the equipment..
