Download or read book Salmonine Introductions to the Laurentian Great Lakes written by Stephen Scott Crawford and published by NRC Research Press. This book was released on 2001 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication provides an historical review and evaluation of documented ecological effects associated with salmonine introductions to the Laurentian Great Lakes. The introduction of salmonines to the Great Lakes date back to the 1870s, when natural populations of native salmonines in the Great Lakes were in severe decline. Using established evaluation protocols, it was determined that there is evidence of significant ecological effects in six different categories: (1) diseases and parasites, (2) predation on native species, (3) competition for limiting resources, (4) genetic alteration, (5) environmental alteration and (6) community alteration. Taken together, this body of evidence supports the conclusion that the ongoing introduction of non-native salmonines poses an ecologically-significant risk to the Great Lakes ecosystem and its native organisms, and that the introductions should be terminated.

Download or read book Atlantic Salmon in Maine written by National Research Council and published by National Academies Press. This book was released on 2004-09-07 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the pervasive and substantial decline of Atlantic salmon populations in Maine over the past 150 years, and because they are close to extinction, a comprehensive statewide action should be taken now to ensure their survival. The populations of Atlantic salmon have declined drastically, from an estimated half million adult salmon returning to U.S. rivers each year in the early 1800s to perhaps as few as 1,000 in 2001. The report recommends implementing a formalized decision-making approach to establish priorities, evaluate options and coordinate plans for conserving and restoring the salmon.

Available in PDF, EPUB and Kindle. Book excerpt: Local author Susan Peterson Gateley tracks down the real Maid of the Mist and investigates the meaning behind the names Soup Harbor, Sheba Island and the Devil's Nose. Named by the Hurons, "Ontario" means "Lake of Shining Waters." Beneath this gleaming surface, though, the easternmost of the Great Lakes hides enigmas from thousands of years of history. Ghosts linger on the surface, and monsters swim below, frightening sailors on the water. Smugglers used Lake Ontario during the War of 1812 and Prohibition and continue to do so today--Ontario's darkness providing the cover needed to elude law enforcement. Join Gateley as she delves deep below the waves to uncover these and other legends, lore and secrets from Lake Ontario.
