The Alaska Department of Fish and Game, Division of Sport Fish, has assessed the annual run of Buskin River sockeye salmon (Oncorhynchus nerka) on Kodiak Island, Alaska, since 1990. Buskin River sockeye salmon weir counts were 4,284, 12,297, 7,741, and 2,330 fish for 2018–2021, respectively. Weir counts for Lake Louise were 83, 73, 53, and 1,896 sockeye salmon for 2018–2021, respectively. Reported annual subsistence harvests for the Buskin River Section were 474, 836, and 1,620 sockeye salmon for 2018–2020, respectively; accurate harvest is not available for 2021 at this time. In interviews conducted with 11 subsistence users in 2019, 100% reported that the Buskin River was a traditional fishing location, and 73% reported that they subsistence fished in other areas. Interviews were not conducted in 2018 due to a low run or in 2020 and 2021 due to COVID-19. Enumerated sockeye salmon spawning escapement for the entire drainage (Buskin Lake and Louise Lake weirs) was 4,367, 12,370, 7,794, and 4,226 fish for 2018–2021, respectively. Based on a Bayesian spawner–recruitment analysis of the Buskin Lake system, estimated spawning escapement for maximum sustained yield is about 5,700 fish (95% credibility interval = 4,300–8,000). A sustained yield probability analysis supports the current Buskin Lake system biological escapement goal (BEG) range of 5,000–8,000 sockeye salmon. Age-1.2, -1.3, -2.2, and -2.3 sockeye salmon composed 93–99% of the Buskin River run. Male to female ratios for the Buskin River were between 0.6 and 1.1 to 1 for 2018–2021. Samples taken from the Lake Louise sockeye salmon run and the subsistence harvest were too low to provide reliable estimates of age and sex composition.

The salmon that symbolize the Pacific Northwest's natural splendor are now threatened with extinction across much of their ancestral range. In studying the natural and human forces that shape the rivers and mountains of that region, geologist David Montgomery has learned to see the evolution and near-extinction of the salmon as a story of changing landscapes. Montgomery shows how a succession of historical experiences -first in the United Kingdom, then in New England, and now in the Pacific Northwest -repeat a disheartening story in which overfishing and sweeping changes to rivers and seas render the world inhospitable to salmon. In King of Fish , Montgomery traces the human impacts on salmon over the last thousand years and examines the implications both for salmon recovery efforts and for the more general problem of human impacts on the natural world. What does it say for the long-term prospects of the world's many endangered species if one of the most prosperous regions of the richest country on earth cannot accommodate its icon species? All too aware of the possible bleak outcome for the salmon, King of Fish concludes with provocative recommendations for reinventing the ways in which we make environmental decisions about land, water, and fish.

A natural history and celebration of the famous bears and salmon of Brooks River. On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America’s greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them (with as many as forty-three bears sighted in a single day), and thousands of people come to watch in person or on the National Park Service’s popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous in three parts. The first forms an ecological history of the region, from its dormancy 30,000 years ago to the volcanic events that transformed it into the Valley of Ten Thousand Smokes. The central and longest section is a deep dive into the lives of the wildlife along the Brooks River, especially the bears and salmon. Readers will learn about the bears’ winter hibernation, mating season, hunting rituals, migration patterns, and their relationship with Alaska’s changing environment. Finally, the book explores the human impact, both positive and negative, on this special region and its wild population.

In 2010, the Alaska Department of Fish and Game, Division of Sport Fish, initiated a 2-year study to evaluate the feasibility of annually estimating the total abundance of sockeye salmon smolt (Oncorhynchus nerka) emigrating from the Buskin River drainage in the Kodiak Management Area. This report presents data collected during the 2010 and 2011 study years, in which smolt counts were obtained using floating incline plane and modified Canadian fan trap designs. Total abundance was assessed using census counts, mark-recapture experiments, and genetics-based mixed stock analysis.

The Alaska Department of Fish and Game, Division of Sport Fish has used a weir to assess the annual runs of coho salmon (Oncorhynchus kisutch) to the Buskin River on Kodiak Island since 1985. This report presents weir counts, harvest, and age-composition data collected for 2018 and 2019. In 2018, the inriver run estimate was 4,523 fish; the estimated sport and subsistence harvests were 1,793 fish and 1,171 fish, respectively, and the commercial harvest was zero. The estimated escapement was 4,164 coho salmon. Age-2.1 fish composed an estimated 78.9% of the inriver run and the male-to-female ratio was 2.4:1. In 2019, the inriver run estimate was 5,537 fish; the estimated sport and subsistence harvests were 934 fish and 340 fish, respectively, and the commercial harvest was zero. The estimated escapement was 5,350 coho salmon. Age-2.1 fish composed 52.3% of the inriver run and the male-to-female ratio was 1.1:1.
