Federal treaties

Explanation:

Native Indian Americans have been dependent on hunting and fishing way before the land was colonized by settlers. They depend on these practices not only for food but also for trade, medicines etc. When they decided to give up their land to the federal government, various treaties were signed between them and the government. These treaties continued to give them the rights to fishing and hunting even on reserved water bodies and land. Many of the fishing regulations that apply to the rest of the Americans are not applied to the natives and they enjoy exclusive fishing rights in many places.
