The main purpose of this legislation is to include Rhode Island in the Mid-Atlantic Fishery Management Council. This council is responsible for managing fishery resources in the Mid-Atlantic region, which includes states like New York, New Jersey, and Delaware. By adding Rhode Island, the law aims to ensure that the interests and needs of Rhode Island's fishing community are represented in decisions that affect local fisheries. Key provisions of the legislation involve specific amendments to an existing law known as the Magnuson-Stevens Fishery Conservation and Management Act.
