What are the rods you have? Are they fly rods, spin or float?
And what fish are you wanting to catch?
BTW – most freshwater fish is quite edible (so long as it is big enough to make anything meaningful from it).
The problem you will have is just plonking a line with bait of some kind on the end into a river/stream/lake etc with no idea of being able to read the conditions, understand where fish might be, what fish you expect to find, how you will bait to catch them will just lead to you going very hungry I reckon.
You would be better off shooting rabbits.
Edit – when I am older and greyer I am going to start fishing again – spent my teen years permanently camped by the River Nidd in Yorkshire – I even regularly took a poacher’s rod to school in my bag so I could fish at lunchtime.
