Abstract: | The stocking of trout in wilderness lakes of the western United States began in the 1800s. This practice was followed for
nearly a century with the singular goal of creating and enhancing sport fishing and without any consideration of its ecological
ramifications. Following the advent of a new environmental awareness in the 1960s, and thanks to new research that revealed
negative impacts on the biota attributable to introduced fishes, traditional fish-stocking practices came under question first
at federal land management agencies and later at their counterparts within the states. The highly utilitarian ethic that drove
resource management until well into the 1960s was gradually replaced by one that acknowledges the value of all life forms
and their ecological complexity, a view currently supported even by many anglers. The necessity for wilderness fish stocking
is now the subject of widespread debate, especially in view of changing social values and priorities. Options for future generations
cannot be preserved if introductions continue to erode the biodiversity of mountain lake ecosystems.
