Amended Recovery Strategy for the Atlantic Whitefish (Coregonus Huntsmani) in Canada


Book Description

"The Atlantic Whitefish, Coregonus huntsmani, is an endemic Canadian species historically known to occur only in the Tusket River and Petite Rivière watersheds in southwestern Nova Scotia. The species is the sole and founding representative of a unique lineage of Whitefish in North America; it is therefore an important component of Canadian biodiversity. As a result of the species' reduced distribution and presumed low abundance, the Atlantic Whitefish was assessed as 'Endangered' by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 1984; a designation which means the species is at imminent risk of extinction. This 'Endangered' status was re-confirmed by COSEWIC in 2000 and 2010. This amended recovery strategy restates the overall goal and broad strategies that continue to be relevant and realistic to protect and recover Atlantic Whitefish. The overall goal of the recovery strategy is to: "Achieve stability in the current population of Atlantic Whitefish in Nova Scotia, reestablishment of the anadromous form, and expansion beyond its current range.""--Executive summary, p. vii, viii.

[...] Recovery Strategy Progress Report for the Atlantic Whitefish 2016 Preface Section 46 of the Species at Risk Act (SARA) requires the competent Minister to report on the implementation of the recovery strategy for a species at risk, and on the progress towards meeting its objectives within five years of the date when the recovery strategy was placed on the SAR Public Registry. [...] The accomplishment of a number of scientific achievements, management activities undertaken, and the initiation of a number of recovery efforts have assisted in progress towards ensuring that the Recovery Strategy goal is achieved and will require the continued implementation of additional actions, which have been identified and prioritized in the Action Plan for the species. [...] Key to recovery success is adopting an adaptive management approach and ensuring the timely implementation of the measures required for recovery (as identified in the Action Plan) which will require the continued commitment and cooperation of the AWCRT and other partners including the potential establishment of new partnership arrangements, careful consideration and management of both financial an [...] The Schedule of Studies in the Recovery Strategy accordingly outlines the research activities required to refine the current description of critical habitat within the Petite lakes to support its protection and to identify any additional habitat areas required for the species subsequent recovery, such that all required critical habitat is eventually identified to fully achieve the population and d.




Action Plan for the Atlantic Whitefish (Coregonus Huntsmani) in Canada


Book Description

"The Atlantic Whitefish, Coregonus huntsmani, is globally unique and therefore a significant component of Canada's biodiversity. The species was historically found in only two watersheds in southwestern Nova Scotia, Canada: the Tusket River in Yarmouth County and the Petite Rivière in Lunenburg County. Currently the only wild self-sustaining population of Atlantic Whitefish exists largely restricted within three small, interconnected, semi-natural lakes in the upper Petite Rivière drainage area. This action plan addresses the species' entire global distribution with the intent of implementing the overall recovery goal of the recovery strategy, which is to: "Achieve stability in the current population of Atlantic Whitefish in Nova Scotia, re-establishment of the anadromous form, and expansion beyond its current range""--Executive summary, p. iv.




Supplementation Options to Aid Recovery of the Endangered Atlantic Whitefish (Coregonus Huntsmani)


Book Description

"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.




Proceedings of a Workshop on a Decision Support Tool for Stocking of Atlantic Whitefish


Book Description

Atlantic whitefish (Coregonus huntsmani) are indigenous to Nova Scotia but are confined to a single watershed, the Petite Riviere near Bridgewater. The species is listed as endangered, and a recovery plan has an objective of introducing captive reared Atlantic whitefish to another water body in order to lower the risk of species extinction. This report presents proceedings of a workshop held to investigate the best approach & information requirements needed to develop a decision support framework to guide the selection of new habitats for the recovery of the Atlantic whitefish. Topics of presentations include a proposal for whitefish stocking, the fish transfer & introduction process, tools for environmental decision making, and the requirements of a decision support tool. The appendix includes a copy of the National Code on Introductions & Transfers of Aquatic Organisms.
