This 11th Commandment is not to be found in any of the usual religious textbooks; it has been passed down, generation by generation, from one angler to another by word of mouth, and in more modern times by those who write about the sport of fishing. Fortunately, violations of the 11th do not result in eternal damnation. In fact, violators may sometimes catch more fish, a point that is nearly ignored in the pages of angling literature.
