Download or read book The Effects of Noise on Aquatic Life written by Arthur N. Popper and published by Springer Nature. This book was released on 2024-10-28 with total page 2138 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this landmark new work, the major authorities in the field from around the world present a wealth of research data, coverage of regulatory issues, and thinking about the effects of man-made noise on marine mammals, turtles, amphibians, fishes, and invertebrates. The various themes of the book were chosen to cover the wide range of basic and cutting edge information on this topic. They include the hearing abilities of aquatic animals; communication by means of underwater sound; the description of aquatic soundscapes; different sound sources and their characteristics; the effects of sound on behavior; and assessing, mitigating, and monitoring the effects of aquatic noise. Emphasis is on the cross-fertilization of ideas and findings across species and noise sources. With over 140 contributions from leading researchers, the sources of underwater sound and their effects are discussed in detail.

Download or read book Geostatistics for Estimating Fish Abundance written by J. Rivoirard and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geostatistics is a branch of spatial statistics that was originally developed for the mining industry. The technique is now widely recognised as an important tool for the estimation of the abundance and distribution of natural resources. However, new developments have been required to extend its application to fisheries science, particularly in variogram estimation. This important new title describes the fundamentals of geostatistics in terms more familiar to life-scientists, and uses case studies on seven commercially important fish stocks to demonstrate its application to fisheries survey data. Comprehensive and practical advice is given on how this new method can be used to estimate the abundance (with an appropriate measure of precision) of fish stocks worldwide. Geostatistics for Estimating Fish Abundance will be of vital interest to fisheries research scientists, marine biologists, oceanographers, marine and fish ecologists, environmental scientists and experts involved in the assessment of natural animal resources. The book has been developed as a result of studies carried out by a collaborative team of international researchers expert in this area with financial support from the Commission of the European Communities, AIR specific RTD programme. J. Rivoirard and N. Bez are at the Centre de Géostatistique de Fontainebleau, Ecole des Mines de Paris, France, J. Simmonds and P. Fernandes are at the FRS Marine Laboratory, Aberdeen, UK and K. Foote is at the Institute of Marine Research, Bergen, Norway and at Woods Hole Oceanographic Institution, USA.

Available in PDF, EPUB and Kindle. Book excerpt: In this new book, experts from the Institute of Marine Research in Bergen synthesize our current understanding of both basic and applied fish behaviour and, in light of the many advances of recent years, examine the influence of fish behaviour on fish capture and abundance estimation. Marine Fish Behaviour is an essential source of up-to-date and topical information an practical, professional guidance for fisheries technologists, gear manufactureres fisheries researchers and fishermen.

Download or read book Fisheries Sonar written by R. B. Mitson and published by Wiley-Blackwell. This book was released on 1991-01-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with all aspects of modern echo-sounding and sonar as used by those concerned with the exploitation and management of fisheries. From the basic physics, through the operation of the systems, the practical aspects are well illustrated with many diagrams and photographs, including a large section on paper recordings and colour sounder displays of fish traces. The applications described range from a small portable echo-sounder for freshwater fishing in shallow waters to the Deep Tow echo-sounder used at 2500m depth. it includes some remarkable accoustic images of underwater scenes and the latest methods for tracking fish.
