That is pretty enlightening. I didn't realize everything that went into hunting. However, I think the point of fishing without killing fish was more about catch and release. In catch and release, you can succeed, but still let the fish live. In hunting, (correct me if I'm wrong) success is determined by the kill. There's no way to "win" at hunting without killing the deer. I guess you could just stalk deer, pantomime shooting them, then leaving, but I've never heard of that

My husband and I hunt on our property. We spend a LOT of time “catch and releasing” so to speak. We spend time in blinds and stands and just observe. 

It lets us keep an eye on the health of the herd. We get to make sure everyone is healthy, eating well, etc. 

By keeping tabs on the herd it gives us a better idea
Of what to hunt to keep the population stable and healthy.
