註釋This publication provides a historical review and evaluation of documented ecological effects associated with salmonine introductions to the Laurentian Great Lakes. Salmonines are members of the salmonid sub-family Salmoninae and includes the charrs, the Atlantic salmons, and the Pacific salmons. The history begins with details of the pioneering work of Samuel Wilmot, who established the first government-operated fish hatchery in North America at Newcastle, Ontario in 1866. The introduction of the various species of salmonines is described and the objectives for such introductions are noted along with patterns in trends of salmonine introductions to the Great Lakes Basin from 1870 to the present. The effects of introduction are then evaluated, first with reference to effects on the introduced fish (survival, growth, development, dispersion, migration, reproduction, alteration of life history characteristics) and then the effects on the Great Lakes ecosystem. Using established evaluation protocols & a review of scientific literature & technical reports from the past four decades, evidence of significant ecological effects is presented in six categories: diseases & parasites; predation; competition; genetic alteration; environmental alteration; and community alteration. Finally, lessons learned from the history of non-native salmonine introductions are discussed.
