(Christopher John), 1973- Physical containment approaches to mitigate potential escape of European-origin Atlantic salmon in south coast Newfoundland aquaculture operations [electronic resource] / C.J. Bridger, D.W. Fredriksson, and Ø. Jensen. Méthodes de confinement physique visant à réduire les échappées potentielles de saumon de l’Atlantique d'origine européenne dans le cadre des opérations aquacoles menées dans la côte sud de Terre-Neuve Ottawa : Fisheries and Oceans Canada, 2015. vi, 54 p. : fig., graphs, maps, tables. Canadian Science Advisory Secretariat research document, 1919-5044 ; 2015/072, National Capital Region "December 2015." Includes bibliographic references. This paper will provide a broad overview of freshwater and saltwater operations typically employed to raise Atlantic salmon on fish farms. An analysis follows of the very limited data available globally (sourced from Norway and Scotland) pertaining to the causes and scale of aquaculture escapes. An effort is made to determine the likelihood and severity of escapes by identifying the various causes and prioritizing mitigation options to prevent escapement. These areas will provide the greatest return on investment for the commercial operators and government regulators to prevent escapes. A detailed discussion is included to describe the causes for escapes as they relate to commercial aquaculture equipment and operations used presently in the Atlantic salmon farming industry. The list of mitigation options is compiled from global strategies already implemented in specific jurisdictions or other methods that are considered to provide a reasonable return on investment based on the discussion presented throughout this paper. gccst Fish farming gccst Fisheries management Canada.
