Sergey and Anatoly shared success stories they’d heard, describing the Sakhalin salmon councils’ progress toward combating poaching; restoring and monitoring salmon streams; educating the public; and promoting community involvement in fishery management. Concerned about the damage poaching has caused to the salmon population in their local river, the people and administration welcomed the idea of public salmon councils and began working to create one of their own. Less than a year later, in January of 2011, Ust-Bolsheretsk’s District Mayor Igor Bondar established the Ust-Bolsheretsk Public Salmon Council by official decree. Comprised of local stakeholders, including representatives from regional govern- ment and enforcement agencies, educators, commercial fishermen, and local and indigenous people, the council acts as a conduit for ideas to be discussed and then proposed to relevant government agencies. The council also operates as a forum, addressing important issues such as: the fight against poaching, how to best develop ecotourism, local access rights, the value of traditional fishing practices, Photo by Michel Roggo, WWF-Canon Michel by Roggo, Photo public outreach and education, stream restoration and monitoring, and overall n Sockeye salmon return upStream to spawn. watershed management.

  • Russia): 2003–9 Results
    CHAPTER 6 OBSIDIAN PROVENANCE STUDIES ON KAMCHATKA PENINSULA (FAR EASTERN RUSSIA): 2003–9 RESULTS Andrei V. Grebennikov, Vladimir K. Popov, Michael D. Glascock, Robert J. Speakman, Yaroslav V. Kuzmin, and Andrei V. Ptashinsky Abstract: The results of obsidian provenance research on the Kamchatka Peninsula based on extensive study of the chemical composition of volcanic glasses from both ‘geological’ sources and archaeological sites are presented. At least 16 geochemical groups reflecting different sources of obsidian have been identified for Kamchatka using Instrumental Neutron Activation Analysis. Seven sources of archaeological obsidian have been linked to specific geologic outcrops, with the distances between sites and obsidian sources up to 550km. At least seven geochemical groups based only on artefact analysis are also described. The use of multiple obsidian sources was a common pattern during the Palaeolithic, Neolithic, and Palaeometal periods of Kamchatkan prehistory.

Bugaev ASIAN SOCKEYE SALMON (freshwater period of life, biological structure, population dynamics) Edited by William E. Ricker and Richard J. Beamish Petropavlovsk-Kamchatsky Publishing House “Kamchatpress” 2011 УДК 338.24:330.15 ББК 28.693.32 Б90 Victor F. Bugaev. Asian Sockeye Salmon (freshwater period of life, biological structure, population dynamics). – Petropavlovsk-Kamchatsky : Publishing House “Kamchatpress”, 2011: 292 p. ISBN 978-5-9610-0159-4 Abstract Key words: sockeye, age, length, weight, growth, scale structure, freshwater period, food competitors, infestation, food supply, population dynamics, fishing operations. In Asia, the sockeye is the most abundant on the Kamchatka Peninsula in some years where ap- proximately 90-95 % of all the Asian sockeye is harvested in the watersheds of the Kamchatka and Ozernaya rivers alone. This study is a summary of long-term observations on the Asian sockeye, and is based on the results of the author's 20 years of research. He examines the biological charac- teristics of 38 local sockeye populations (from Iturup Is. to Eastern Chukotka). Long-term data was used to analyze the interannual variability in the growth of juvenile sockeye of the Kamchatka and Ozernaya rivers. Questions concerning the structural analysis of the scales in juveniles and spawn- ers of the sockeye are discussed in detail for the purpose of standardizing the age-determination procedure. Data on the feeding behaviour of juvenile sockeye in the watersheds of the Kamchatka and Ozernaya rivers are presented, and questions concerning the food competition of fish in the Kamchatka River watershed are discussed.

Yet, very few dollars are made through legal harvesting of fish. Corrupt from inside out, the industry channels billions through centralized government bureaucracy, threatening to destroy the region's ecosystem and its centerpiece, wild salmon. Every summer in Kamchatka during spawning season poachers kill millions of salmon to produce hundreds of tons of red caviar, a prized commodity. A handful of Russian and American environmentalists confront the poachers at great personal risk. But can they effectively fight those who pay millions in bribes to law officers, who share with local government, who share with Moscow bureaucrats? In CAVIAR TRAIL, director Daniel Levin follows environmentalists and poachers as they chase each other along the red caviar money trail that leads from Kamchatka all the way to Kremlin.
