题目内容：
We commonly think of sportsmanship in connection with athletic contests, but it also applies to individual outdoor sports. Not everyone who picks up a fishing rod or goes out with a gun is a sportsman. The sportsman first of all obeys the fish and game laws, not because he is liable to be punished as a violator, but because he knows that in the main these laws are made for his best interests.The following are some of the things that those who would qualify for membership in the sportsmanship fraternity （圈内人） will do.
1. Take no more game than the bag limit provided for by the fish and game laws. The person who comes back from a trip boasting about the large number of fish or game taken is not a sportsman but a game hog （贪得无厌的捕猎者）.
2. Observe the unwritten rules of fair play. This means shooting game birds only when the birds are “on the wing”. For the same reason, do not use a shotgun to shoot a rabbit or similar animal while it is sitting or standing still.
3. Be careful in removing illegal or undersized fish from the hook. This should be done only after wetting the hands. This is necessary because the body of the fish is covered with a thin, protective film which will stick to your dry hands. If the hands are dry when the fish is handled, the film is torn from the body of the fish. Without the protective film, the fish is more easily attacked by diseases. If you wish to release a fish that is hooked in such a way that it will be impossible to be close to the hook as convenient. In a remarkably short time, the hook will break down and the fish will remain almost unharmed. Fish have been known to feed successfully while hooks were still in their lips.
4. Be sure of the identity of your target before you shoot. Many useful and harmless species of wildlife are thoughtlessly killed by the uninformed person who is out with a gun to kill whatever flies within range.
In what respect does the author think individual outdoor sports are similar to athletic contests?
