Download or read book Sampling Statistics in the Atlantic Menhaden Fishery written by Alexander J. Chester and published by . This book was released on 1984 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic menhaden, Brevootia tyrannus, the object of a major purse-seine fishery along the U.S. east coast, are landed at plants from northern Florida to central Maine. The National Marine Fisheries Service has sampled these landings since 1955 for length, weight, and age. Together with records of landings at each plant, the samples are used to estimate numbers of fish landed at each age. This report analyzes the sampling design in terms of probability sampling theory. The design is classified as two-stage cluster sampling, the first stage consisting of purse-seine sets randomly selected from the population of all sets landed, and the second state consisting of fish randomly selected from each sample set. Implicit assumptions of this design are discussed with special attention to current sampling procedures. Methods are developed for estimating mean fish weight, numbers of fish landed, and age composition of the catch, with approximate 95% confidence intervals. Based on specific results from three ports (Port Monmouth, N.J., Reedville, Va., and Beaufort, N.C.) for the 1979 fishing season, recommendations are made for improving sampling procedures to comply more exactly with assumptions of the sampling design. These recommendations include adopting more formal methods for randomizing set and fish selection, increasing the number of sets sampled, considering the bias introduced by unequal set sizes, and developing methods to optimize the use of funds and personnel.

Download or read book Stewarding the Sound written by Leah Bendell and published by CRC Press. This book was released on 2019-05-13 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stewarding the Sound uses different perspectives to build awareness of the wealth and fragility of this ecosystem by balancing economic and social needs with conservation. This book, the first ever compilation of the ecological importance of the Sound, demonstrates the cumulative stresses that are now occurring within the Sound and the impact that these stresses are having on the ecosystem. This contributed volume will provide the means of reaching a wide audience to spread awareness of how ecologically important this region is and that it requires a sound management plan so that its ecosystem and the services that ecosystem provides are not compromised.
Download or read book Transients written by John K.B. Ford and published by UBC Press. This book was released on 2011-11-01 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on transient killer whales. Enigmatic and elusive, these mammal-hunting whales are difficult animals to study. They travel in small groups, often moving unpredictably, which makes them less conspicuous than the larger resident pods. For these and other reasons, our understanding of the life history and ecology of transient killer whales has lagged behind that of residents. Transients contains the latest information on the natural history of transient killer whales, including their feeding habits, social lives, and distribution patterns. The catalogue section contains photographs of and notes on over 200 individual whales. Numerous sidebars contain interesting observations on encounters with transients as well as information on how and where to best watch them.
Download or read book Human Impacts on Seals Sea Lions and Sea Otters written by Todd J. Braje and published by Univ of California Press. This book was released on 2011-03-23 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than ten thousand years, Native Americans from Alaska to southern California relied on aquatic animals such as seals, sea lions, and sea otters for food and raw materials. Archaeological research on the interactions between people and these marine mammals has made great advances recently and provides a unique lens for understanding the human and ecological past. Archaeological research is also emerging as a crucial source of information on contemporary environmental issues as we improve our understanding of the ancient abundance, ecology, and natural history of these species. This groundbreaking interdisciplinary volume brings together archaeologists, biologists, and other scientists to consider how archaeology can inform the conservation and management of pinnipeds and other marine mammals along the Pacific Coast.

Book excerpt: "On April 30, 1994, Public Law 103-238 was enacted allowing significant changes to provisions within the Marine Mammal Protection Act (MMPA). Interactions between marine mammals and commercial fisheries are addressed under three new sections. This new regime replaced the interim exemption that has regulated fisheries-related incidental takes since 1988. Section 117, Stock Assessments, required the establishment of three regional scientific review groups to advise and report on the status of marine mammal stocks within Alaska waters, along the Pacific Coast (including Hawaii), and the Atlantic Coast (including the Gulf of Mexico). This report provides information on the marine mammal stocks of Alaska under the jurisdiction of the National Marine Fisheries Service"--Preface.

Download or read book Environmental Contaminants and Endocrine Health written by Oliana Carnevali and published by Elsevier. This book was released on 2023-05-30 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Contaminants and Endocrine Health focuses specifically on contaminants with hormonal disrupting activities. The book provides insights into the multiple effects of endocrine-disrupting chemicals (EDCs) and their mechanism of action (MoA) on metabolism, reproduction and the multiple physiological roles of the endocannabinoid system which has recently been indicated as new target. The content systematically covers EDC sources and effects, EDCs as sources of disease and health impairment in laboratory models, EDCs as the cause of disease and health impairment in humans and wild species, and the removal of hazardous pollutants from wastewaters to highlight intervention, mitigation and adaptation for reduced threat. This content will be a foundational resource for academic and research staff in endocrinology and hormone toxicology as well as for professors, researchers and students in these areas. - Includes important foundational coverage of the endocrine system, definitions of EDC sources and descriptions, model examples and mechanisms of action biological effects - Provides coverage of EDC effects in humans and animals, from metabolic alterations to epidemiological studies of fertility and metabolism - Presents insights into the confirmed and suspected human diseases spectrum with origins linked to EDC exposure, including cancers, intellectual disabilities, autism, birth defects of the urethra (hypospadias), decreased sperm count, increased rates of miscarriage, obesity, type 2 diabetes, and more
