Book Synopsis Mortality of Fish Escaping Trawl Gears by : Petri Suuronen
Download or read book Mortality of Fish Escaping Trawl Gears written by Petri Suuronen and published by Food & Agriculture Org.. This book was released on 2005 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress has been made in reducing bycatch and discards through improving the selectivity of fishing gear. This publication examines the key factors affecting the stress, injury and mortality of fish arising from fishing processes, particularly when fish escape from trawl equipment. It seeks to identify improved methodological approaches and practices, and to consider the design of fishing gears and operations that reduce or eliminate such deaths, and to assess the problems associated with estimating the impact of unaccounted fish mortality.

Available in PDF, EPUB and Kindle. Book excerpt: Touching on the wide array of people and events who have brought life to the history of the Placentia area, The Placentia Area - A Changing Mosaic offers a glimpse of the deep history that has transformed this part of Newfoundland and Labrador. The history is a collection of interconnected stories. Geological processes forged a landscape that would feature in later actions and activities. Geology created a wide expansive beach that Basque fish harvesters discovered was perfect for drying fish. This attribute, along with its deep harbour, then ensured that Placentia would go on to function in the struggles between the French and English. And from this period, the Placentia area has evolved, playing a role in the lives of well-known characters such as Pierre le Moyne d'Iberville or Roger F. Sweetman, as well as the less known, yet equally important, women and men who simply came to make a life for themselves. To the present day, the latter has remained a defining quality of the region.

Book Synopsis The Effects of Windchill Exposure on the Snow Crab, Chionoecetes Opilio by : Jonathan James Warrenchuk
Download or read book The Effects of Windchill Exposure on the Snow Crab, Chionoecetes Opilio written by Jonathan James Warrenchuk and published by . This book was released on 2001 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Millions of snow crabs, 'Chionoecetes opilio, ' are aerially exposed during sorting in the annual Bering Sea commercial fishery. A laboratory experiment measured snow crab responses to windchill exposure. Crabs were exposed to 8 to 16 m/s windspeed and air temperatures from -2 to -10 C̊ for 5 minutes. Mortality, autonomy, and righting response were assessed for seven days post-treatment. Crabs experienced 40% to 100% mortality at windchill from -10 to 16 C̊. Reduced exposure time significantly reduced mortality. Autonomy was variable but pronounced below -10 C̊ windchill. The righting response was impaired after all but the least severe treatment. Estimates of mortality of discarded snow crab in 1998 were calculated from deadloss of retained crab, a windchill model, and a temperature/windspeed model. No relationship existed between catch deadloss and the windchill conditions when the crabs were caught. Mortality of non-retained snow crab was estimated at 3.6% by the windchill model and 19.6% by the temperature /windspeed model"--Leaf 3.

Book Synopsis Biological Field Techniques for Chionoecetes Crabs by : Luke S. Jadamec
Download or read book Biological Field Techniques for Chionoecetes Crabs written by Luke S. Jadamec and published by Alaska Sea Grant College Program. This book was released on 1999 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This important publication enables standardization of data collection by fisheries observers and shoreline samplers, crab and shellfish biologists, and fishermen. Wide use of the book promises to improve data accuracy, and thus promote good management for these commercially important crabs. When data are collected citing this publication, there should be little or no ambiguity as to measurements made and definitions used. This guide is not all inclusive, but is intended to identify structures and organs, measurements and descriptions, and techniques that are commonly used in field studies"--p. vi.
Book Synopsis Overview of mitigation measures to reduce the incidental catch of vulnerable species in fisheries by : Sacchi, J.
Download or read book Overview of mitigation measures to reduce the incidental catch of vulnerable species in fisheries written by Sacchi, J. and published by Food & Agriculture Org.. This book was released on 2021-06-23 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potentially harmful contact between fisheries and marine vulnerable species represents a global conservation issue and efforts to mitigate the negative repercussions of these interactions belong in strategies for ensuring the sustainability of fisheries. This literature review offers a survey of mitigation measures and techniques that have been developed and tested around the world, aiming to address both the incidental catch of highly mobile species – specifically, cetaceans, seabirds, sharks and rays, and sea turtles – and depredation caused by dolphins. Based on research detailed in over 300 documents, including peer-reviewed publications, reports from international organizations and papers available on the internet, most of the mitigation techniques illustrated are still under development, with only a few already adopted through legislation. The selected mitigation measures are grouped by main types of fishing gear – gillnets and trammel nets, longlines and lines, trawls, purse seines, traps and pots – and further subdivided according to which of the four main groups of vulnerable species – cetaceans, seabirds, sharks and rays, or sea turtles – they are designed to protect. Preventive and curative approaches covering both technical measures (gear modifications, strategies, as well as acoustic, visual, magnetic and chemosensory deterrents) and management measures are described.
Book Synopsis In the Wrong Place - Alien Marine Crustaceans: Distribution, Biology and Impacts by : Bella S. Galil
Download or read book In the Wrong Place - Alien Marine Crustaceans: Distribution, Biology and Impacts written by Bella S. Galil and published by Springer Science & Business Media. This book was released on 2011-04-01 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Wrong Place: Alien Marine Crustaceans - Distribution, Biology And Impacts provides a unique view into the remarkable story of how shrimps, crabs, and lobsters – and their many relatives – have been distributed around the world by human activity, and the profound implications of this global reorganization of biodiversity for marine conservation biology. Many crustaceans form the base of marine food chains, and are often prominent predators and competitors acting as ecological engineers in marine ecosystems. Commencing in the 1800s global commerce began to move hundreds – perhaps thousands – of species of marine crustaceans across oceans and between continents, both intentionally and unintentionally. This book tells the story of these invasions from Arctic waters to tropical shores, highlighting not only the importance and impact of all prominent crustacean invasions in the world's oceans, but also the commercial exploitation of invasive crabs and shrimps. Topics explored for the first time in one volume include the historical roots of man's impact on crustacean biogeography, the global dispersal of crabs, barnacle invasions, insights into the potential scale of tropical invasions, the history of the world's most widely cultured shrimp, the invasive history and management of red king crabs in Norway, Chinese mitten crabs in England, and American blue crabs in Europe, the evolutionary ecology of green crabs, and many other subjects as well, touching upon all ocean shores.

This book was released on 2020-02-28 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Worldwide review of bottom fisheries in the high seas in 2016 is an update to the first Worldwide review of bottom fisheries in the high seas, published in 2009 based on information from 2003 to 2006. It provides states and other interested parties with a summary of the current status of high seas bottom fisheries worldwide. The present, updated review begins with a description of the demersal finfish and shellfish resources, before offering a global perspective on fisheries and management; it then provides specific, regional information over eleven chapters covering the high seas of the world’s oceans, by region. Drawing on data up to and including 2016, it provides a survey of the current state of bottom fisheries since the original Worldwide review, considering these fisheries in the context of their historical evolution.
