What Is the Marine Mammal Protection Act?

The Marine Mammal Protection Act, or MMPA, is the U.S. federal law restricting human actions that affect marine mammals. The MMPA was signed into law in 1974 by President Richard Nixon, making it one of many environmental policies established by the Nixon administration. One of the most significant actions taken under the MMPA was the establishment of an “optimum sustainable yield” (OSY). Instead of the traditional single-species approach to marine mammal management, OSY focuses on the role of marine mammals in the health of an ecosystem. The ecosystem-based approach remains widely implemented across the fishery industry today. >click to read< 11:03
