Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Book excerpt: Sedimentary coasts with their unique forms of life and productive ecosystems are one of the most threatened parts of the biosphere. This volume analyzes and compares ecological structures and processes at sandy beaches, tidal mudflats and in shallow coastal waters all around the world. Analyses of local processes are paired with comparisons between distant shores, across latitudinal gradients or between separate biogeographic provinces. Emphasis is given to suspension feeders in coastal mud and sand, to biogenic stabilizations and disturbances in coastal sediments, to seagrass beds and faunal assemblages across latitudes and oceans, to recovery dynamics in benthic communities, shorebird predation, and to experimental approaches to the biota of sedimentary shores.

This variety of interactions is due to four main interrelated factors: the wide range of fishing gear and practices; very intensive fishing; a high diversity of exploited habitats, ranging from shallow water to the deep-sea and oceanic domain; and high biological diversity.

Book excerpt: This publication examines recent experimental studies of the impact of towed fishing gears, such as trawls and scallop dredges, on benthic habitats and communities (organisms that live at or near the bottom of the sea). The review gives a critical evaluation of the methodological limitations of impact studies, given the complexity and natural variability of benthic communities.

Book excerpt: Fisheries science in North America is changing in response to a changing climate, new technologies, an ecosystem approach to management and new thinking about the processes affecting stock and recruitment. Authors of the 34 chapters review the science in their particular fields and use their experience to develop informed opinions about the future. Everyone associated with fish, fisheries and fisheries management will find material that will stimulate their thinking about the future. Readers will be impressed with the potential for new discoveries, but disturbed by how much needs to be done in fisheries science if we are to sustain North American fisheries in our changing climate. Officials that manage or fund fisheries science will appreciate the urgency for the new information needed for the stewardship of fish populations and their ecosystems. Research organizations may want to keep some extra copies for a future look back into the thoughts of a wide range of fisheries professionals. Fisheries science has been full of surprises with some of the surprises having major economic impacts. It is important to minimize these impacts as the demand for seafood increases and the complexities of fisheries management increase.

Book excerpt: Seventeen-year-old Addisyn Parker is used to being different. From an early age, she's had the ability to see otherworldly creatures with shimmering skin and glowing irises that are completely imaginary to everyone else. Her sporadic hallucinations continually haunt her to no end. Addisyn's life takes an unexpected turn when an absurdly handsome stranger, Drake Carpathia, reveals a sudden interest in her. Despite her best efforts in evading him, Drake's unwavering advances are not something that can be ignored. There's something different about him-an entrancing secret that Addisyn finds hard to resist. Unexplainable events start to unfold as Drake submerges her into a world full of possibilities that Addisyn thought only existed in myths and legends. Strange, paranormal events start happening around her, including frequent visits from one of the ethereal beings who seems hell-bent on stalking her. With all of the supernatural chaos, Addisyn literally has no option but to believe the impossible or risk living a life shrouded by insanity.

Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.

Available in PDF, EPUB and Kindle. Book excerpt: While John Cabot's landfall may be in dispute, what he discovered is not: cod-and lots of them... Historic accounts say that Cabot lowered a basket weighted with stones into the North Atlantic, then hauled it back up brimming with cod. The discovery of these fertile fishing grounds set of a centuries-long struggle among Basque, Portuguese, French, and English fishermen, and established a pattern of far-flung coastal settlements, called outports by Newfoundlanders, that ring the island. And so the legend fits today: the Grand Banks became Valhalla, a miraculous, self-sustaining Eight Wonder of the world, feeding the known world for 500 years. The catastrophic collapse of the fisheries, circa 1992, was unprecedente4d. An ecological disaster to rival any other-the destruction of the Amazonian rainforest notwithstanding-in modern history. This made-in-Canada plunder was part human greed, part stupidity, and part rapacity. Tarnishing Canada's standing within the international community, it holds the reputation of Canada's once-vaunted fisheries scientists up to ridicule. Sixteen years later, no one has taken accountability or apologized for the ruination of a centuries-old way of life and, taken accountability or apologized for the ruination of a centuries-old way of life and, more shocking, a stock recovery plan has yet to be produced... There can be no forgetting-or forgiving-such catastrophic pillaging, Sparked by a second wave of environmentalism focusing on the state of the world's oceans, the Grand Banks cod collapse became a talking point, a sujet noir, now studied at universities and fisheries research centres, wherein students from around the world repeat this mantra: we must never allow our fisheries to go the way of the Grand Banks cod.
