This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific Herring play a critical role in the food web of the Salish Sea. The Cherry Point stock, centered 30 miles north of Bellingham Bay, has declined roughly 97% since the 1970s. This massive decline is a point of concern for environmental and fishery managers and has led to research into both the initial decline and the stock's inability to recover. One key data gap in need of research is whether the Cherry Point herring stock is experiencing increased predation from the nearshore fish, bird, and invertebrate community due to its unique late spawn timing and spawning behavior. To that end, I investigated predation on herring spawn by deploying predator exclusion enclosures and remote underwater time lapse cameras at spawning locations of both the declining Cherry Point stock and Semiahmoo Bay, a nearby stock with stable population trends. Bird surveys in 2021 indicate that avian abundance was highest before spawning occurred and that most birds had left the spawning area before eggs were deposited. The exclusion of avian, large fish, and invertebrate predators from accessing the eggs did not significantly affect the survival of eggs when compared to areas exposed to predation from these groups. There was significant egg mortality in both the control and excluded plots over the spawning period. Remote underwater time-lapse cameras showed higher abundances of fish predators and greater predator diversity at the Cherry Point spawning site compared to Semiahmoo Bay, but this could be driven by seasonal differences. A non-metric multidimensional scaling analysis of the time-lapse data showed slight differences between pre-spawn predator assemblages and predator assemblages during and after the incubation period. This study shows that while predation from larger fauna did not have a significant impact on Pacific Herring egg survival for the years of 2021 and 2022, egg mortality was high and is likely influenced by a multitude of factors including spawning time and habitat, water temperature, and numerous smaller fish and invertebrate species that take advantage of the lipid-rich food source.
Download or read book Time and Complexity in Historical Ecology written by William Balée and published by Columbia University Press. This book was released on 2006-06-22 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of studies by anthropologists, botanists, ecologists, and biologists is an important contribution to the emerging field of historical ecology. The book combines cutting-edge research with new perspectives to emphasize the close relationship between humans and their natural environment. Contributors examine how alterations in the natural world mirror human cultures, societies, and languages. Treating the landscape like a text, these researchers decipher patterns and meaning in the Ecuadorian Andes, Amazonia, the desert coast of Peru, and other regions in the neotropics. They show how local peoples have changed the landscape over time to fit their needs by managing and modifying species diversity, enhancing landscape heterogeneity, and controlling ecological disturbance. In turn, the environment itself becomes a form of architecture rich with historical and archaeological significance. Time and Complexity in Historical Ecology explores thousands of years of ecological history while also addressing important contemporary issues, such as biodiversity and genetic variation and change. Engagingly written and expertly researched, this book introduces and exemplifies a unique method for better understanding the link between humans and the biosphere.

Download or read book The Unnatural History of the Sea written by Callum Roberts and published by Island Press. This book was released on 2009-01-05 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity can make short work of the oceans’ creatures. In 1741, hungry explorers discovered herds of Steller’s sea cow in the Bering Strait, and in less than thirty years, the amiable beast had been harpooned into extinction. It’s a classic story, but a key fact is often omitted. Bering Island was the last redoubt of a species that had been decimated by hunting and habitat loss years before the explorers set sail. As Callum M. Roberts reveals in The Unnatural History of the Sea, the oceans’ bounty didn’t disappear overnight. While today’s fishing industry is ruthlessly efficient, intense exploitation began not in the modern era, or even with the dawn of industrialization, but in the eleventh century in medieval Europe. Roberts explores this long and colorful history of commercial fishing, taking readers around the world and through the centuries to witness the transformation of the seas. Drawing on firsthand accounts of early explorers, pirates, merchants, fishers, and travelers, the book recreates the oceans of the past: waters teeming with whales, sea lions, sea otters, turtles, and giant fish. The abundance of marine life described by fifteenth century seafarers is almost unimaginable today, but Roberts both brings it alive and artfully traces its depletion. Collapsing fisheries, he shows, are simply the latest chapter in a long history of unfettered commercialization of the seas. The story does not end with an empty ocean. Instead, Roberts describes how we might restore the splendor and prosperity of the seas through smarter management of our resources and some simple restraint. From the coasts of Florida to New Zealand, marine reserves have fostered spectacular recovery of plants and animals to levels not seen in a century. They prove that history need not repeat itself: we can leave the oceans richer than we found them.

Download or read book Regional Fisheries Oceanography of the California Current System written by Sam McClatchie and published by Springer Science & Business Media. This book was released on 2013-09-30 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The California Current System is one of the best studied ocean regions of the world, and the level of oceanographic information available is perhaps only surpassed by the northeast and northwest Atlantic. The current literature (later than 1993) offers no comprehensive, integrated review of the regional fisheries oceanography of the California Current System. This volume summarizes information of more than 60-year California Cooperative Oceanic Fisheries Investigation (CalCOFI). While providing a large bibliography, the intent was to extract themes relevant to current research rather than to prepare a compendious review of the literature. The work presents a useful review and reference point for multidisciplinary fisheries scientists and biological oceanographers new to working in the California Current System, and to specialists wishing to access information outside their core areas of expertise. In addition it aims to deliver an up to date reference to the current state of knowledge of fisheries oceanography in the California Current System.
Download or read book The Archaeology of North Pacific Fisheries written by Madonna L. Moss and published by University of Alaska Press. This book was released on 2011-11-15 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: For thousands of years, fisheries were crucial to the sustenance of the First Peoples of the Pacific Coast. Yet human impact has left us with a woefully incomplete understanding of their histories prior to the industrial era. Covering Alaska, British Columbia, and Puget Sound, The Archaeology of North Pacific Fisheries illustrates how the archaeological record reveals new information about ancient ways of life and the histories of key species. Individual chapters cover salmon, as well as a number of lesser-known species abundant in archaeological sites, including pacific cod, herring, rockfish, eulachon, and hake. In turn, this ecological history informs suggestions for sustainable fishing in today’s rapidly changing environment.
