A US lawmaker has introduced legislation making climate change, diversity and technology a more central focus of US fisheries law.

The Sustaining America’s Fisheries for the Future act, introduced by Democratic California lawmaker Jared Huffman this week, would update the Magnuson-Stevens Fishery Conservation and Management Act, which governs fishing in all US federal waters.

"One of the greatest long-term threats to the viability of commercial and recreational fisheries is the continuing degradation of marine ecosystems, including the loss of marine, estuarine, and other aquatic habitats, including as a result of changing environmental conditions associated with climate change," the legislation reads.
