One little item to not overlook, making an edible food from fish caught!
Fishing is relaxing, fun and a real pleasure. Often we "catch and release" so the fish can be caught again by someone else, thus not depleting the resource.
There are times that keeping a fish or fishes for that special camp meal is really an experience not to be missed.
The trick is, you need to know how to clean and perhaps scale the fish, and how to prepare the fish by a variety of means. It is not hard, just one more skill to be looking into. CHeers!
