Abstract Salmonid sport fishery management in Argentinian Patagonia is usually guided by stakeholder perceptions, which do not consider the biological and ecological constraints acting upon aquatic resources. An example of this are policies for Traful Lake, where Atlantic salmon, Salmo salar L., was actively stocked during last decade an attempt to change fish assemblage structure create a highly valuable fishery. This study assesses likelihood these achieving such changes through affluent‐stream suitability as spawning breeding grounds, lake parameters, trophic diversity possible competition due diet overlap. also alternative practices population simulations bioenergetic modelling under diverse catch‐size limit scenarios. concludes that it advisable try generate unique distinctive stocking salmon already renowned Northern Patagonia. Instead, more comprehensive framework decision‐making suggested, involving short‐term studies go beyond specific problem target species incorporate whole using approaches strategies.
