This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. 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.

Commercial and sports fishermen will also find Fish Catching Methods of the World a fascinating and vital reference.
Download or read book A Guide to Bycatch Reduction in Tropical Shrimp trawl Fisheries written by Steve Eayrs and published by Food & Agriculture Org.. This book was released on 2007 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bycatch is the unwanted or non-target part of the catch taken by fishermen. It is either discarded at sea or used for human or animal consumption. The capture of bycatch may pose a threat to species diversity and ecosystem health because this part of the catch is usually unregulated. In tropical shrimp-trawl fisheries, bycatch often consists of juvenile food-fish species and is therefore a threat to food security and sustainable fisheries production. Bycatch is a global problem that must be addressed. This Guide to Bycatch Reduction in Tropical Shrimp-Trawl Fisheries is designed for fishermen, net makers, fishing technologists and others interested in a practical guide to the design, use and operation of effective bycatch reduction devices. Fishery managers, policy-makers and legislators will find this guide useful to help develop specifications governing the design and application of these devices in a shrimptrawl fishery. The issue of bycatch is not going away and scrutiny of fishing activity is increasing. All fishermen are strongly urged to use appropriate bycatch reduction measures to help maintain the productivity of the fishery and the long term prosperity of the fishing industry. By responding appropriately, fishermen can help to protect the marine environment and assist global food security both now and in the future. Also published in French and Spanish.
Download or read book Trawl written by B S Johnson and published by Pan Macmillan. This book was released on 2023-06-29 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an introduction by novelist Jon McGregor. The novel describes, in the first-person, a three-week voyage aboard a deep-sea fishing trawler in the Barents Sea, not unlike the one Johnson undertook in preparation to write the book. Isolating himself from the world he knows, as well as from the ship’s crew, the narrator reflects on past events and relationships, hoping for some kind of redemption. This convincingly authentic and harrowing attempt to get to the heart of the human condition is one of Johnson’s finest novels. In his heyday, during the 1960s and early 1970s, B S Johnson was one of the best-known novelists in Britain. A passionate advocate for the avant-garde, he became famous for his forthright views on the future of the novel and for his unique ways of putting them into practice. Convinced that ‘telling stories is telling lies’ and that he should write about ‘nothing else but what happens to me’, Johnson produced Trawl.

Download or read book Environmental DNA written by Pierre Taberlet and published by Oxford University Press. This book was released on 2018-02-02 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water, feces, or air) without the prior isolation of any target organism. The analysis of environmental DNA has the potential of providing high-throughput information on taxa and functional genes in a given environment, and is easily amenable to the study of both aquatic and terrestrial ecosystems. It can provide an understanding of past or present biological communities as well as their trophic relationships, and can thus offer useful insights into ecosystem functioning. There is now a rapidly-growing interest amongst biologists in applying analysis of environmental DNA to their own research. However, good practices and protocols dealing with environmental DNA are currently widely dispersed across numerous papers, with many of them presenting only preliminary results and using a diversity of methods. In this context, the principal objective of this practical handbook is to provide biologists (both students and researchers) with the scientific background necessary to assist with the understanding and implementation of best practices and analyses based on environmental DNA.

Download or read book Oceana written by Ted Danson and published by Rodale Books. This book was released on 2011-03-15 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most people know Ted Danson as the affable bartender Sam Malone in the long-running television series Cheers. But fewer realize that over the course of the past two and a half decades, Danson has tirelessly devoted himself to the cause of heading off a looming global catastrophe—the massive destruction of our planet's oceanic biosystems and the complete collapse of the world's major commercial fisheries. In Oceana, Danson details his journey from joining a modest local protest in the mid-1980s to oppose offshore oil drilling near his Southern California neighborhood to his current status as one of the world's most influential oceanic environmental activists, testifying before congressional committees in Washington, D.C.; addressing the World Trade Organization in Zurich, Switzerland; and helping found Oceana, the largest organization in the world focused solely on ocean conservation. In his incisive, conversational voice, Danson describes what has happened to our oceans in just the past half-century, ranging from the ravages of overfishing and habitat destruction to the devastating effects of ocean acidification and the wasteful horrors of fish farms. Danson also shares the stage of Oceana with some of the world's most respected authorities in the fields of marine science, commercial fishing, and environmental law, as well as with other influential activists. Combining vivid, personal prose with an array of stunning graphics, charts, and photographs, Ocean powerfully illustrates the impending crises and offers solutions that may allow us to avert them, showing you the specific courses of action you can take to become active, responsible stewards of our planet's most precious resource—its oceans.

Download or read book Fisherman s Workbook written by J. Prado and published by Wiley. This book was released on 1991-01-15 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unusual pocketbook, designed for fishermen, netmakers, boatbuilders and other professionals, provides easy reference on land or sea, to a wealth of useful information. It is presented in five parts. The first helps with the choice and use of materials; the second with the choice of fishing gear; the next outline the characteristics of echo sounders and deck machinery for handling fishing gear. Then comes information on the most effective use of fishing vessels, and guidelines for calculating costs and benefits of fishing operations. Finally basic formulae and tables are given and a section on ordering equipment. Fishing technologies are not dependent on exact science, for individual experience, knowledge and skill are of great importance. This workbook therefore contains sets of guidelines drawn from the wide experience of master fishermen, to be used in combination with the individual's own experiences, knowledge and expertise.
