The bill is a memorial from the Washington State Legislature urging Congress to amend the Marine Mammal Protection Act to provide greater flexibility for states and tribes in managing pinniped populations, particularly in relation to the recovery of endangered salmon stocks. It references the success of the Endangered Salmon Predation Prevention Act of 2018, which allowed for the lethal removal of sea lions in a specific area of the Columbia River, and highlights findings from the Washington State Academy of Sciences that indicate pinniped populations are negatively impacting salmon populations.

The memorial calls for the expansion of adaptive management tools, including lethal removal, to be applicable across all marine shorelines and the Puget Sound, rather than being limited to the current authorized segment of the Columbia River. The resolution emphasizes the need for Congress to act in order to enable state and tribal resource managers to implement these recommended strategies for salmon recovery effectively.
