This book was released on 2021 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a summary of escapement goal recommendations for major salmon stocks of the Upper Copper River and Prince William Sound Management Areas. Escapement goals were reviewed based on the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222) and the Policy for Statewide Salmon Escapement Goals (5 AAC 39.223) adopted by the Alaska Board of Fisheries into regulation in 2001. The escapement goal committee reviewed 29 existing escapement goals, including 1 Chinook Oncorhynchus tshawytscha, 5 chum O. keta, 2 coho O. kisutch, 16 pink O. gorbuscha (8 goals for each even- and odd-year brood line), and 5 sockeye O. nerka salmon stocks. The escapement goal committee recommends escapement goals be updated for 5 stocks: Copper River Chinook salmon, Copper River Delta and Bering River coho salmon, and Bering River and Coghill Lake sockeye salmon. The escapement goal committee recommends that no modifications be made to the other existing salmon escapement goals and that no goals be eliminated or created at this time.

Escapement goals were reviewed based on the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222) and the Policy for Statewide Salmon Escapement Goals (5 AAC 39.223) adopted by the Alaska Board of Fisheries into regulation in 2001. The escapement goal committee reviewed 29 existing escapement goals, including 1 Chinook Oncorhynchus tshawytscha , 5 chum O. keta , 2 coho O. kisutch, 16 pink O. gorbuscha (8 goals for each even- and odd-year brood line), and 5 sockeye O. nerka salmon stocks. The escapement goal committee also reviewed escapement data for Gulkana River Chinook salmon, but decided not to consider establishing an escapement goal until a sufficient time series of data are available to better understand how well the current tower count project indexes escapement. All of the existing goals were adopted in 2002, 2005, 2008, or 2011 except for the 2 coho salmon goals that were adopted in 1991. The escapement goal committee recommends all Chinook, chum, and pink salmon escapement goals be updated. The escapement goal committee recommends no modifications be made to the existing coho and sockeye salmon escapement goals, and that no goals are eliminated or created at this time.

Available in PDF, EPUB and Kindle. Book excerpt: During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.

Download or read book Run Reconstruction Spawner recruit Analysis and Escapement Goal Recommendation for Chinook Salmon in the Copper River written by Philip John Joy and published by . This book was released on 2021 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 2018. Bayesian statistical methods were employed to assess uncertainty in the presence of measurement error, serial correlation, and missing data. Ricker spawner–recruit parameters and management reference points were estimated, including the escapement that provides for maximum sustained yield (SMSY). An additional analysis was performed on a subset of data from 1999 to 2018 that used only mark–recapture estimates of escapement and excluded abundance indices used in the full data set. The full data set produced an SMSY of 22,844 spawners (95% credibility interval of 12,920–84,942 spawners) and the 1999–2018 data set produced an SMSY of 26,951 spawners (95% credibility interval of 15,371–98,262 spawners). Different results may be partially explained by differences in data structure and may also indicate reduced productivity in more recent years. It is important to note that many escapements observed since 1999 were greater than those observed prior to 1999 and the increased contrast in observed escapements increased information and our understanding of true underlying stock production. After examining both analyses, it is recommended that a sustainable escapement goal range of 21,000 to 31,000 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.
