5203 |a“Recent unauthorized introductions of non-native piscivorous fishes into endangered Atlantic whitefish (Coregonus huntsmani) habitat have elevated concern for the prospects for their survival and eventual recovery. Range extension could reduce dependency for species survival on the continued viability of the localized population that exists in the three small semi-natural lakes within the Petite Rivière that define the global distribution of Atlantic whitefish. The likelihood is low that range extension will occur from natural colonization of new habitat. Supplementation, or stocking, fish within the natural historic range of Atlantic whitefish may be required to increase the abundance of the naturally reproducing populations. There is presently minimal documentation, specific to Atlantic whitefish, available to support the development of supplementation activities, or to guide release strategies. This report reviews the challenges that the current status of Atlantic whitefish present to the design and implementation of supplementation activities enacted to aid either survival or recovery. A frame work is proposed to help select stocking methods, stocking locations, and the choice of the stocking target as either enhancement of the existing population, or development of anadromous populations and/or additional freshwater-resident populations. Supplementation actions designed to restore anadromy to the extant Petite Rivière population may currently offer the greatest conservation benefit to Atlantic whitefish”--Abstract, p. v.
