The signatories to this letter commend the JSA for its work on the National Aquaculture Research and Development Strategic Plan and agree with its vision and recognition of aquaculture as a strategic priority for the U.S. However, we suggest that recent aquaculture developments and global trends call for emphasis on a sector of marine aquaculture that is inadequately recognized in this plan. Specifically, we refer to the farming of marine macroalgae or seaweeds.
