Historical abundance of Andreafsky River, Anvik River, and aggregated other upriver stocks of summer chum salmon Oncorhynchus keta was reconstructed from mixed stock harvest data and incomplete sonar, weir, counting tower, and aerial survey data of varying precision from 1972 to 2007. The resulting estimates of escapement and harvest of East Fork Andreafsky River chum salmon were fitted to an age-structured Ricker spawner-recruit model. Bayesian statistical methods were employed, which allowed for realistic assessment of uncertainty in the presence of measurement error, serial correlation, and missing data.

"Fundamentally, the salmon's decline has been the consequence of a vision based on flawed assumptions and unchallenged myths.... We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introduction From a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book: describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million years considers the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of years examines the rapid transformation of the region following the arrival of Europeans presents the history of efforts to protect and restore the salmon offers a critical assessment of why restoration efforts have failed Throughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

This is the story of their unprecedented trek along the northwestern edge of the Pacific Ocean-a year-long journey through some of the most rugged terrain in the world- and their encounters with rain, wind, blizzards, bears, and their own emotional and spiritual demons. Erin and Hig set out from Seattle with a desire to raise awareness of natural resource and conservation issues along their route: clear-cut logging of rainforests; declining wild salmon populations; extraction of mineral resources; and effects of global climate change. By taking each mile step by step, they were able to intimately explore the coastal regions of Washington, British Columbia, and Alaska, see the wilderness in its larger context, and provide a unique on-the-ground perspective. An entertaining and, at times, thrilling adventure, theirs is a journey of discovery and of insights about the tiny communities that dot this wild coast, as well as the individuals there whom they meet and inspire.

An age-structured state-space spawner–recruit model was fit to estimates of relative and absolute abundance, harvest, and age composition for Copper River Chinook salmon (Oncorhynchus tshawytscha) from 1980 to 2016. Bayesian statistical methods were employed to assess uncertainty in the presence of measurement error, serial correlation, and missing data. Ricker stock-recruit parameters and management reference points were estimated, including the escapement that provides for maximum sustained yield (SMSY). It is recommended that a sustainable escapement goal range of 18,500 to 33,000 fish be adopted for Copper River Chinook salmon. Escapement is evaluated by subtracting estimates of inriver harvest from estimates of inriver abundance. Escapements within this range have a high probability of producing sustainable yields.

Each year wild Pacific salmon leave their oceanic feeding grounds and swim hundreds of miles back to their home rivers. The salmon's annual return is a place-defining event in the Pacific Northwest, with immense ecological, economic, and social significance. However, despite massive spending, efforts to significantly alter the endangered status of salmon have failed. In Salmon, People, and Place, acclaimed fisheries biologist Jim Lichatowich eloquently exposes the misconceptions underlying salmon management and recovery programs that have fueled the catastrophic decline in Northwest salmon populations for more than a century. These programs will continue to fail, he suggests, so long as they regard salmon as products and ignore their essential relationship with their habitat. But Lichatowich offers hope. In Salmon, People, and Place he presents a concrete plan for salmon recovery, one based on the myriad lessons learned from past mistakes. What is needed to successfully restore salmon, Lichatowich states, is an acute commitment to healing the relationships among salmon, people, and place. A significant contribution to the literature on Pacific salmon, Salmon, People, and Place: A Biologist's Search for Salmon Recovery is an essential read for anyone concerned about the fate of this Pacific Northwest icon.

Historical escapement and run size of fall chum salmon Oncorhynchus keta was reconstructed from incomplete sonar, weir, counting tower, mark-recapture, aerial survey, and foot survey data of varying precision from 1974 to 2007. The resulting estimates of drainage-wide escapement were fitted to an age-structured Ricker spawner-recruit model. Bayesian statistical methods were employed, which allowed for realistic assessment of uncertainty in the presence of measurement error, serial correlation, and missing data.

Introducing Alaska’s answer to the Pioneer Woman: Two sisters share their remarkable life story as fisherwomen of the Aleutian Islands—plus 50 sustainable seafood recipes that honor the beauty of wild foods. Share in the remarkable and wild lives of Emma Teal Laukitis and Claire Neaton, the Salmon Sisters, who grew up on a homestead in the Aleutians where the family ran a commercial fishing boat in the Alaskan sea. Their book reveals through stories, recipes, and photography this outward-bound lifestyle of natural bounty, the honest work on a boat's deck, and the wholesome food that comes from local waters and land. Here are creative and simple ways to enjoy wild salmon, halibut, and spot prawns, as well as simple crafts and ideas for exploring the natural world. The sisters are committed to sustaining and celebrating the seafaring community in Alaska, and their business of selling products related to and from the ocean donates a can of wild-caught fish to local food banks for each item purchased. “To flip through the pages of Emma Teal Laukities’s and Claire Neaton’s new cookbook . . . is to be whisked away on an adventure in the country’s northernmost state.” —Martha Stewart
