From page 1...
... The charge to the NRC 's Committee onAtIantic Salmon in Maine included an interim report focusing on the genetic makeup of Maine Atiantic salmon populations. This is the interim report.

From page 2...
... At first, young fish were obtained from Lake Ontario, and then the Craig Brook Hatchery, using eggs from Penobscot River fish in Maine, was the stocking source. By the 1920s, Canadian eggs were being used, followed in the 1940s by eggs from the Machias, Penobscot, and Dennys rivers of Maine.

From page 3...
... TO DATA ON GENETICS OF MAINE SALMON The committee's focus in this interim report is on assessing how Maine salmon populations differ from other Atlantic salmon populations and among themselves. The committee has addressed the question at three levels.

From page 4...
... The committee concludes that North American Atlantic salmon are clearly distinct genetically from European salmon. In addition, despite the extensive additions of nonnative hatchery and aquaculture genotypes to Maine's rivers, the evidence is surprisingly strong that the wild salmon in Maine are genetically distinct from Canadian salmon.

From page 5...
... Summa7y 5 streams is similar to patterns seen elsewhere in salmon and their relatives where no stocking has occurred. Maine streams have salmon populations that are genetically as divergent from Canadian salmon populations and from each other as would be expected in natural salmon populations anywhere else in the Northern Hemisphere.
