The term "fair game" is generally not applicable on the high seas, as it implies a concept of ownership or possession of the resources found in international waters. The high seas are considered to be a common heritage of humanity, and the resources therein are subject to international laws and regulations. However, there are certain activities that are considered to be generally acceptable or lawful on the high seas, such as fishing, scientific research, and navigation, as long as they are conducted in accordance with international law.
