Download or read book Southeast Pot Shrimp Stock Status Prior to the 2018 19 Season written by Quinn T. Smith and published by . This book was released on 2020 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spot shrimp Pandalus platyceros, and to a lesser extent coonstripe shrimp P. hysinotis, are targeted by a pot fishery in Southeast Alaska. Spot shrimp are protandric hermaphrodites with fairly narrow temperature and hard-bottom habitat requirements, and there is little Alaska-specific life history information. A fixed-quota harvest strategy is employed to manage the fishery; data are reviewed annually to determine stock status and guideline harvest levels (GHLs) are set within a guideline harvest range (GHR) and targeted inseason. The upper limits of GHRs were originally set based on historical harvest levels but have since been adjusted. Management is supported by a stock assessment program that includes fishery-independent pot surveys in five of 22 management units (accounting for 57% of the 10-year average annual harvest), commercial catch sampling and logbooks, and commercial catch and effort data. Data on catch rate (survey, logbook, and commercial), shrimp size, the length at which 50% are female (L50), and estimates of harvest rate are analyzed annually. Data from the most current season are compared to established baselines and scored to designate a stock status of “good”, “above average”, “moderate”, “below average”, or “poor”. For the 22 management units in Southeast Alaska, stock status was poor in two, below average in three, moderate in five, above average in seven, and good in two. The ‘Remainder of District 12’, District 14 and District 16 management units were closed for the 2017/18 season, so no stock statuses were calculated.

Download or read book Improving Fish Stock Assessments written by National Research Council and published by National Academies Press. This book was released on 1998-02-27 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Available in PDF, EPUB and Kindle. Book excerpt: This publication gives an updated review of the quantity of discards in the world's marine fisheries, using information from a broad range of fisheries in all continents. A number of policy issues are discussed including a 'no discards' approach to fisheries management, the need for balance between bycatch reduction and bycatch utilisation initiatives, and concerns arising from incidental catches of marine mammals, birds and reptiles. The report also highlights the need for more robust methods of estimating discards, and the development of bycatch management plans.

Download or read book Marine Mammals and the Exxon Valdez written by Thomas R. Loughlin and published by . This book was released on 1994 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oil spill disaster that occurred when the Exxon Valdez ran aground has become part of the iconography of ecological disaster. This book synthesizes confidential data, recently released by the US government, concerning the effects of this spill on marine mammals (ie. sea otters, harbour seals, killer whales and humpback whales). Many of the contributors were on site within 24 hours of the spill and their results establish a baseline worst case scenario. These data should assist marine biologists, pathologists, toxicologists, environmentatlists, engineers, and coastal planners in assessing the nature of this disaster.
