This book was released on 2017-12-15 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Variability of Longline Catches of Yellowfin Tuna As a prelude to estimating the variability of the longline catches we will first examine the way in which yellowfin are distributed in space. This will be followed by an empirical examination of the distribution of the catches in order to ascertain a transformation that will permit the application of conventional statistical methods. Finally, the variance will be' estimated as a basis for establishing fiducial limits. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Historical Trends of Tuna Catches in the World written by Makoto Miyake and published by Food & Agriculture Org.. This book was released on 2004 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total world catch of the major commercial tuna species (albacore, bigeye, bluefin, skipjack and yellowfin) has increased during the last 50 years (from 0.4 to 3.9 million tonnes), but the pattern of increase has varied among species, oceans and fishing gears. The Pacific Ocean has been the predominant region in the world catch, with catches from the Indian Ocean having exceeded those from the Atlantic Ocean in recent years. This publication examines historical trends in the catches of these tuna species and considers the causes of the variations.

Download or read book Distribution Relative Abundance and Movement of Skipjack Tuna Katsuwonus Pelamis in the Pacific Ocean Based on Japanese Tuna Longline Catches 1964 67 Classic Reprint written by Walter M. Matsumoto and published by Forgotten Books. This book was released on 2018-02-20 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Distribution, Relative Abundance, and Movement of Skipjack Tuna, Katsuwonus Pelamis, in the Pacific Ocean Based on Japanese Tuna Longline Catches, 1964-67 Certain characteristics of the longline gear affect the catch and catch data. And these should be cited so that conclusions drawn from the data are viewed in the proper perspective. First, the catches of skipjack tuna by this gear are extremely small. In the years 1962-66, for example, the catch of skipjack tuna in the Japanese commercial tuna longline fishery averaged metric tons per year, as compared with an average of metric tons caught by the pole-and-line fishery. The smallness of the catch reflects the inefficiency of the gear for taking this species, but, because of the wide areal coverage by this gear, these data should be useful for determining areas of high or low relative abundance.

Download or read book Tagging and Tracking of Marine Animals with Electronic Devices written by Jennifer L. Nielsen and published by Springer Science & Business Media. This book was released on 2009-06-10 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2nd international tagging and tracking symposium was held in San Sebastian, Spain, in October 2007, seven years after the first symposium was held in Hawaii in 2000 (Sibert and Nielsen 2001). In the intervening seven years, there have been major advances in both the capability and reliability of electronic tags and analytical approaches for geolocation of tagged animals in marine habitats. Advances such as increased data storage capacity, sensor development, and tag miniaturization have allowed researchers to track a much wider array of marine animals, not just large and charismatic species. Importantly, data returned by these tags are now being used in population analyses and movement simulations that can be directly utilized in stock assessments and other management applications. Papers in this volume are divided into three sections, the first describing insights into behavior achieved using acoustic, archival, and novel tags, the second reporting on advances in methods of geolocation, while the final section includes contributions where tag data have been used in management of marine species. Accurate documentation of animal movements and behaviors in critical marine habitats are impossible to obtain with other technologies. The management and conservation of marine species are critical in today’s changing ocean environment and as electronic tags become more accurate and functional for a diversity of organisms their application continues to grow, setting new standards in science and technology.

Download or read book Balancing the Tides written by JoAnna Poblete and published by University of Hawaii Press. This book was released on 2020-03-31 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Balancing the Tides highlights the influence of marine practices and policies in the unincorporated territory of American Sāmoa on the local indigenous group, the American fishing industry, international seafood consumption, U.S. environmental programs, as well as global ecological and native concerns. Poblete explains how U.S. federal fishing programs in the post–World War II period encouraged labor based out of American Sāmoa to catch and can one-third of all tuna for United States consumption until 2009. Labeled "Made in the USA," this commodity was sometimes caught by non-U.S. regulated ships, produced under labor standards far below continental U.S. minimum wage and maximum work hours, and entered U.S. jurisdiction tax free. The second half of the book explores the tensions between indigenous and U.S. federal government environmental goals and ecology programs. Whether creating the largest National Marine Sanctuary under U.S. jurisdiction or collecting basic data on local fishing, initiatives that balanced western-based and native expectations for respectful community relationships and appropriate government programs fared better than those that did not acknowledge the positionality of all groups involved. Despite being under the direct authority of the United States, American Sāmoans have maintained a degree of local autonomy due to the Deeds of Cession signed with the U.S. Navy at the turn of the twentieth century that created shared indigenous and federal governance in the region. Balancing the Tides demonstrates how western-style economics, policy-making, and knowledge building imposed by the U.S. federal government have been infused into the daily lives of American Sāmoans. American colonial efforts to protect natural resources based on western approaches intersect with indigenous insistence on adhering to customary principles of respect, reciprocity, and native rights in complicated ways. Experiences and lessons learned from these case studies provide insight into other tensions between colonial governments and indigenous peoples engaging in environmental and marine-based policy-making across the Pacific and the globe. This study connects the U.S.-American Sāmoa colonial relationship to global overfishing, world consumption patterns, the for-profit fishing industry, international environmental movements and studies, as well as native experiences and indigenous rights. Open Access publication of this book was made possible by the Sustainable History Monograph Pilot, an initiative sponsored by the Andrew W. Mellon Foundation.
