Download or read book Predicting the Effects of Ocean Warming on the Global Distribution of Sea Lice Lepeophtheirus Salmonis and Caligus Elongatus written by Victoria Ngoc Phuong Lai and published by . This book was released on 2020 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea lice are marine ectoparasitic copepods. Commonly found in European and North American waters, these species have caused extensive ecological and economic damage in salmonid aquaculture. The significant impacts of sea lice in farm and wild fish populations has been the key drivers in the rising number of studies on sea lice infestations. While the effects of various environmental factors on the local dispersion patterns and transmission dynamics of sea lice have been observed, the lack of studies on the global sea lice niche have limited our understanding of the effects of climate warming on their distribution and ecology. Building on the existing knowledge of sea lice ecology, response to temperature changes, and their relationships with their fish hosts, I predicted the niche of two sea lice species, Lepeophtheirus salmonis and Caligus elongatus. The MaxEnt models predicted a contraction in the L. salmonis niche range from the past (“Last Glacial Maximum” 22,000 years ago) to the present, but an expansion from the present to the future (year 2100). Distance from land and SST were the primary variables regulating the distribution of L. salmonis. For C. elongatus, the models predicted an expansion from the past to the present, but a contraction from the present to the future. Depth and SST were the primary variable regulating the distribution of C. elongatus. A consequence of these changes on salmon farm management is that farms may become more likely to experience sea lice infestation in the future, particularly by L. salmonis, which may lead to additional ecological and economic impacts in the future. However, additional research is necessary to examine the long-term effects of climate change on the host-parasite system between salmonids and sea lice.
Download or read book Sea Lice Biology and Control written by Jim Treasurer and published by 5m Books Ltd. This book was released on 2022-10-31 with total page 857 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea lice are one of the most important and costly health issues for Atlantic salmon aquaculture and for culture of many other marine fish species. In addition, the extent and causes of impacts of sea lice upon wild salmonids has proven a hotly debated issue and one that continues to affect public perceptions of aquaculture. It is 29 years since the last dedicated book on sea lice biology and management, Pathogens of Wild and Farmed Fish: Sea Lice (Boxshall and Defaye, 1993), and a volume of current perspectives is overdue. The current book updates knowledge concerning the biology and management of sea lice, authored by over 60 world-leading researchers, practitioners and industry experts, written in an accessible and engaging style. New topics include genomics, vaccinology, physiology and epidemiology, and aspects of interactions with wild fisheries are thoroughly reviewed. Sea Lice Biology and Control is of interest to and provides an invaluable reference for sea lice researchers, parasitologists, students, fish farmers, veterinarians and other fish health professionals, wild fish biologists and managers, regulators, government, fish certification professionals and NGOs. The book provides an authoritative overview of sea lice and their interactions and gives a clear illustration of the application of the principles of integrated pest management in an aquaculture context. 5m Books

This book was released on 2019-06-07 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A remarkable accomplishment.... [This volume] has been and will continue to be a major force advancing freshwater fish parasitology."—Ernest H. Williams Jr., from the ForewordThis thoroughly revised and updated edition of a classic reference work is the definitive guide to the identification of the parasites of freshwater fishes of North America. The book provides information on public health concerns about fish parasites, the methods used to examine fish for parasites, and those parasites found only in very selective organs or tissues. It lists the known species of each genus, along with reference citations that enable readers to find literature pertinent to species identification, life cycles, and in some cases, control. In the heart of the book, each chapter opens with a description of a phylum and its relevant families and genera, followed by a species list for those genera. Drawings illustrate a representative of each genus, and are supplemented by photographic examples.Many new parasites of North American freshwater fishes have been discovered since the publication of the first edition thirty years ago. For this new edition, the author has added new species accounts and revised the taxonomy, expanded descriptions and discussion of the most important fish parasites, provided a glossary to aid nonspecialists, and updated the reference list through 1992. The volume features twice as many illustrations as the first edition, including the addition of 33 color photographs.
Download or read book A Speck in the Sea written by John Aldridge and published by Hachette Books. This book was released on 2017-05-23 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The harrowing adventure-at-sea memoir recounting the heroic search-and-rescue mission for lost Montauk fisherman John Aldridge, which Daniel James Brown calls "A terrific read." I am floating in the middle of the night, and nobody in the world even knows I am missing. Nobody is looking for me. You can't get more alone than that. You can't be more lost. I've got too many people who love me. There's no way I'm dying like this. In the dead of night on July 24, 2013, John Aldridge was thrown off the back of the Anna Mary while his fishing partner, Anthony Sosinski, slept below. As desperate hours ticked by, Sosinski, the families, the local fishing community, and the U.S. Coast Guard in three states mobilized in an unprecedented search effort that culminated in a rare and exhilarating success. A tale of survival, perseverance, and community, A Speck in the Sea tells of one man's struggle to survive as friends and strangers work to bring him home. Aldridge's wrenching first-person account intertwines with the narrative of the massive, constantly evolving rescue operation designed to save him.
Download or read book Coastal Environments in the West of Ireland written by John B. Roney and published by Cambridge Scholars Publishing. This book was released on 2022-11-16 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-authored study explores how the natural sciences and the humanities together can understand the connections between the natural environment, the built environment, and the cultural heritage of communities along the west coast of Ireland. Knowledge of the sea and marine life, and what they mean to humanity is dependent on both scientific study and local knowledge, which, in turn, can lead to a greater commitment to sustainability. Until the 1950s, there was little government support for scientific research, nor an interest in helping fisheries beyond near shore catch. Irish fisheries remained small, underfunded, and had difficulty accessing international markets. However, as this book shows, Ireland’s cultural heritage demonstrates a deep appreciation for the coastal environment and a sense of place. This is preserved in the Irish language, in poetry, story and music, and in the ways the Irish lived with an often-wild coastal topography.

Available in PDF, EPUB and Kindle. Book excerpt: The North American freshwater fish fauna is the most diverse and thoroughly researched temperate fish fauna in the world. Ecology of North American Freshwater Fishes is the only textbook to provide advanced undergraduate and graduate students and researchers with an up-to-date and integrated view of the ecological and evolutionary concepts, principles, and processes involved in the formation and maintenance of this fauna. Ecology of North American Freshwater Fishes provides readers with a broad understanding of why specific species and assemblages occur in particular places. Additionally, the text explores how individuals and species interact with each other and with their environments, how such interactions have been altered by anthropogenic impacts, and the relative success of efforts to restore damaged ecosystems. This book is designed for use in courses related to aquatic and fish ecology, fish biology, ichthyology, and related advanced ecology and conservation courses, and is divided into five sections for ease of use. Chapter summaries, supplemental reading lists, online sources, extensive figures, and color photography are included to guide readers through the material and facilitate student learning. Part 1: Faunal origins, evolution, and diversity Presents a broad pictureÑboth spatially and temporallyÑof the derivation of the fauna, including global and regional geological and climatological processes and their effects on North American fishes. Part 2: Formation, maintenance, and persistence of local populations and assemblages Focuses on how local fish populations and assemblages are formed and how they persist, or not, through time. Part 3: Form and function Deals with the relationship of body form and life history patterns as they are related to ecological functions. Part 4: Interactions among individuals and species Discusses the numerous interactions among individuals and species through communication, competition, predation, mutualism, and facilitation. Part 5: Issues in conservation Focuses on several primary conservation issues such as flow alterations and the increasing biotic homogenization of faunas.
Download or read book Salmon Wars written by Catherine Collins and published by Henry Holt and Company. This book was released on 2022-07-12 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Pulitzer Prize-winning correspondent and a former private investigator dive deep into the murky waters of the international salmon farming industry, exposing the unappetizing truth about a fish that is not as good for you as you have been told. A decade ago, farmed Atlantic salmon replaced tuna as the most popular fish on North America’s dinner tables. We are told salmon is healthy and environmentally friendly. The reality is disturbingly different. In Salmon Wars, investigative journalists Douglas Frantz and Catherine Collins bring readers to massive ocean feedlots where millions of salmon are crammed into parasite-plagued cages and fed a chemical-laced diet. The authors reveal the conditions inside hatcheries, where young salmon are treated like garbage, and at the farms that threaten our fragile coasts. They draw colorful portraits of characters, such as the big salmon farmer who poisoned his own backyard, the fly-fishing activist who risked everything to ban salmon farms in Puget Sound, and the American researcher driven out of Norway for raising the alarm about dangerous contaminants in the fish. Frantz and Collins document how the industrialization of Atlantic salmon threatens this keystone species, endangers our health and environment, and lines the pockets of our generation's version of Big Tobacco. And they show how it doesn't need to be this way. Just as Eric Schlosser’s Fast Food Nation forced a reckoning with the Big Mac, the vivid stories, scientific research, and high-stakes finance at the heart of Salmon Wars will inspire readers to make choices that protect our health and our planet.
Download or read book Leeches Lice and Lampreys written by Graham C. Kearn and published by Springer Science & Business Media. This book was released on 2007-11-05 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young. This book explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals. The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the host’s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone interested in fishes and in this neglected field of British natural history. With the enquiring naturalist in mind, terms and concepts are explained as they arise, backed up by a glossary, and the text is liberally illustrated. An introductory chapter on fish biology sets the scene and common fish names are used throughout, as well as scientific names.

Download or read book New Directions in Conservation Medicine written by A. Alonso Aguirre and published by Oxford University Press. This book was released on 2012-05-28 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, species and ecosystems have been threatened by many anthropogenic factors manifested in local and global declines of populations and species. Although we consider conservation medicine an emerging field, the concept is the result of the long evolution of transdisciplinary thinking within the health and ecological sciences and the better understanding of the complexity within these various fields of knowledge. Conservation medicine was born from the cross fertilization of ideas generated by this new transdisciplinary design. It examines the links among changes in climate, habitat quality, and land use; emergence and re-emergence of infectious agents, parasites and environmental contaminants; and maintenance of biodiversity and ecosystem functions as they sustain the health of plant and animal communities including humans. During the past ten years, new tools and institutional initiatives for assessing and monitoring ecological health concerns have emerged: landscape epidemiology, disease ecological modeling and web-based analytics. New types of integrated ecological health assessment are being deployed; these efforts incorporate environmental indicator studies with specific biomedical diagnostic tools. Other innovations include the development of non-invasive physiological and behavioral monitoring techniques; the adaptation of modern molecular biological and biomedical techniques; the design of population level disease monitoring strategies; the creation of ecosystem-based health and sentinel species surveillance approaches; and the adaptation of health monitoring systems for appropriate developing country situations. New Directions of Conservation Medicine: Applied Cases of Ecological Health addresses these issues with relevant case studies and detailed applied examples. New Directions of Conservation Medicine challenges the notion that human health is an isolated concern removed from the bounds of ecology and species interactions. Human health, animal health, and ecosystem health are moving closer together and at some point, it will be inconceivable that there was ever a clear division.
