This is simply control over the quality of the raisers. There are many additional considerations for the raising per se, such as how large the coop should be, and even that one must have a large hunting area, and raise pheasants oneself to provide for the hawk each day. In this way, there will be no side-effects on other wild animals in the area.
這只是對養者品質的控制，養鷹還有許多附加要件，如鷹舍該有多大，甚至規定要有一大片獵場，自行豢養雉雞，每天供鷹狩獵，以免影響野外其他生物族群。
