Book excerpt: Non-native Brook Trout Salvelinus fontinalis were introduced throughout western North America in the early 1900s, resulting in widespread self-sustaining non-native populations that are difficult to eradicate and often threaten native salmonid populations. A novel approach to eradicating undesirable Brook Trout populations is using YY male (MYY) Brook Trout. YY male Brook trout are created in the hatchery by feminizing XY males and crossing them with normal XY males. When MYY Brook Trout reproduce successfully with wild females, all offspring are males. This can potentially be used to shift the sex ratio of the wild population toward males, potentially reaching a point where no females remain in the population to reproduce, thus eliminating the population. We stocked fingerling (mean = 126 mm; range = 75–184 mm) MYY Brook Trout in three streams and four lakes in 2020, and catchable (mean = 284 mm; range = 189–340 mm) MYY Brook Trout in two streams and two lakes in 2020 to attempt to eradicate wild Brook Trout in these study systems; these waters have now been stocked for several years, some as early as 2015. Prior to stocking, we suppressed wild Brook Trout via mechanical removal in two streams and two lakes to potentially increase survival of stocked MYY Brook Trout, and therefore decrease the time to eradication. Suppression via mechanical removal in 2020 was 77% in Dry Creek, 46% in Pike’s Fork Creek, 28% in Martin Lake, and 41% in Seafoam Lake #4. This long-term study is scheduled to be completed in 2026.

Book excerpt: The first Wild Trout Symposium (1974) was sponsored by Trout Unlimited and the United States Department of the Interior. The second Symposium (1979) added the Federation of Fly Fisherman as a sponsor. Five years later (1984) the U.S. Department of Agriculture - Forest Service joined. In 1989 , the U.S. Environmental Protection Agency and the American Fisheries Society joined. These symposia began with a concentration on management, then recognized that more than 'management' was required in ongoing efforts to enhance wild salmonid fisheries. Subsequent symposia began to examine a broader range of environmental and social factors influencing wild salmonids. The originators hoped that each symposium would be a building block upon which the succeeding symposium could provide insights and research which future sessions could revisit. Along with the broadening of sponsorship, we have grown , we have gained recognition, and we look forward to expanding our contribution to the cause of wild salmonids. We hope these Proceedings will stimulate readers thinking and efforts on behalf of our wild salmonid resources , and plan to participate with us in Wild Trout V.

Available in PDF, EPUB and Kindle. Book excerpt: Anders Halverson provides an exhaustively researched and grippingly rendered account of the rainbow trout and why it has become the most commonly stocked and controversial freshwater fish in the United States. Discovered in the remote waters of northern California, rainbow trout have been artificially propagated and distributed for more than 130 years by government officials eager to present Americans with an opportunity to get back to nature by going fishing. Proudly dubbed an entirely synthetic fish by fisheries managers, the rainbow trout has been introduced into every state and province in the United States and Canada and to every continent except Antarctica, often with devastating effects on the native fauna. Halverson examines the paradoxes and reveals a range of characters, from nineteenth-century boosters who believed rainbows could be the saviors of democracy to twenty-first-century biologists who now seek to eradicate them from waters around the globe. Ultimately, the story of the rainbow trout is the story of our relationship with the natural world--how it has changed and how it startlingly has not.
