Nearly all fishing is subject to quotas, allowed seasons, licensing, allowed tackle, type and number of lines or net types, excluded (closed) areas, allowed size range, allowed catch size, and other restrictions. The jurisdictions and roles of several state and federal agencies often overlap in the maritime domain giving rise to an alphabet soup of agencies and jurisdictions. Each state normally maintains joint jurisdiction over the first (3 nautical mile) of their coastal waters. The main agency charged with ensuring deep sea fishing regulations and restrictions in the United States exclusive economic zone (EEZ) of (200 nautical miles) off its shores are enforced on the high seas by the United States Coast Guard.
