Book Description
"This booklet is for small-scale fisherman. It explains how an echo-sounder can improve fishing by suppling information on water depth, presence of fish and sea bottom conditions. It describes how an echo-sounder works, with examples of installation, operation and maintenance."--Page [4] of cover.

Book Description
The Detection of Fish is a guide on how to locate fish through the indications of its presence in the area and the use of different acoustic instruments. The book has seven chapters, which cover the different types and locations of fisheries; the evaluation of resources of exploratory fishing; the position of fisheries; the two fish detection methods; basic principles of acoustics in relation to fishing; and the estimation of abundance of fish with an echo sounder. Also covered are the study of behavior of fish through acoustic means; the deep scattering layer and its different investigations; and the use of more complex acoustic instruments. The text is recommended for beginning fishermen, entrepreneurs who wish to venture in the fishing business, and those who work for government agencies who oversee fishing and aquatic resources. Marine biologists, especially those concerned with the study of fish, would also find the book as a handy guide.

Book Description
This book discusses in depth many of the key problems in non-equilibrium physics. The origin of macroscopic irreversible behavior receives particular attention and is illustrated in the framework of solvable models. An updated discussion on the linear response focuses on the correct electrodynamic aspects, which are essential for example, in the proof of the Nyquist theorem. The material covers the scaling relationship between different levels of description (kinetic to hydrodynamic) as well as spontaneous symmetry breaking in real time in terms of nonlinear dynamics (attractors), illustrated using the example of Bose-Einstein condensation. The presentation also includes the latest developments - quantum kinetics - related to modern ultrafast spectroscopy, where transition from reversible to irreversible behavior occurs.

Book Description
Until now, there has not been any work that systematically presents the subject of acoustic fish reconnaissance, details all major aspects of applying acoustic equipment in commercial fish reconnaissance, and offers sufficient analysis of the effectiveness of fish-finding techniques. Acoustic Fish Reconnaissance responds to this need by providing t
