Maine’s wild Atlantic salmon remain genetically distinct despite more than a century of fish-stocking, aquaculture escapes, and other threats to the species, according to an independent report prepared by the U.S. National Academy of Sciences. The report undermines the claim by Maine Gov. Angus King (I) and others that Maine salmon were genetically diluted and therefore did not merit protection under the federal Endangered Species Act. More than a year ago, the species was declared endangered in eight Maine rivers, much to the consternation of aquaculture and agriculture industries, which worried about the economic impact. Shortly thereafter, the state appealed the listing.
