You should really check out the writing of Roderick Haig-Brown
. He wrote about conservation, the love of the outdoors (rivers in particular), the life cycle of fish and the excitement of fishing.
This is from an article in the Spring 1998 issue of the Heritage Post -
"Haig-Brown wrote that Isaak Walton, the 17th Century author of The Compleat Angler, "knew, perhaps more fully than any other man ever has, the sources of fulfillment and freshness that were to be found in the countryside and in his gentle art." That Haig-Brown, who released many more fish than he ever kept, found his own source of fulfillment in "the gentle art" of fishing, is clear from the final paragraph of A River Never Sleeps:
I still don't know why I fish or why other men fish, except that we like it and it makes us think and feel. But I do know that if it were not for the strong, quick life of rivers, for their sparkle in the sunshine, for the cold grayness of them under rain and the feel of them about my legs as I set my feet hard down on rocks or sand or gravel, I should fish less often. A river is never quite silent; it can never, of its very nature, be quite still; it is never quite the same from one day to the next. It has its own life and its own beauty, and the creatures it nourishes are alive and beautiful also. Perhaps fishing is, for me, only an excuse to be near rivers. If so, I'm glad I thought of it."
