Download or read book The Control of Fish Migration written by R.J.F. Smith and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish migration is important and spectacular. Migratory fish gather energy in one portion of the environment and transport it to other areas, where it often becomes available to humans or to other elements in the ecosystem. Migration brings fish into situations that allow easy harvest as they concentrate along migration routes. Their journeys also make them vulnerable to human intereference at critical points along their route. Salmon, for example, may harvest plankton in the open ocean and transport that food energy to coastal and inland regions, where it is captured by fisheries or deposited in inland streams and utilized by the flora and fauna of the region. These salmon are able to complete journeys of thousands of kilometers from their natal streams to oceanic feeding grounds and back to the same home streams, an accomplishment that strains our credi bili ty . We now understand some of the timing and guiding stimuli used in these migrations, and mechanisms can be logically proposed, on the basis of the established abilities of fishes, to account for the unexplained portions of the migrations. There is no single factor guiding these fish. Instead, they are dependent on the presence in their environment of a great variety of appropriate orienting and timing stimuli. These stimuli are vulnerable to human interference. The more widespread and easily available the information on these requirements, the more readily fish can be protected from such interference.

This book was released on 2013-03-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.

This book was released on 2012-12-06 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chance Favors Only the Prepared Mind How does a scientist go about the task of pushing back the curtains of the unknown? Certainly the romance of tackling the mysteries of nature provides the motivation, for who would not be inspired by the remarkable life history of this romantic beast, the salmon. After living in the Pacific Ocean for several years, salmon swim thousands of kilometers back to the stream of their birth to spawn. I have always been fascinated by the homing migration of salmon. Noone who has seen a 20-kilogram salmon fling itself into the air repeatedly until it is exhausted in a vain effort to surmount a waterfall can fail to marvel at the strength of the instinct that draws the salmon upriver to the stream where it was born. But how does it find its way back? I was puzzling over this problem during a family vacation in 1946. Inspired by the work of the great German Nobel Laureates, Karl von Frisch and Konrad Lorenz, I had been conducting research with my graduate student Theodore Walker, since 1945, on the ability of fishes to discriminate odors emanating from aquatic plants. Von Frisch had studied schooling minnows and discovered that, if broken, their skin emitted a con specific chemical substance, termed Schreckstoff, which caused other members of its school to disperse and hide.

Download or read book Animal Homing written by F. Papi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homing phenomena must be considered an important aspect of animal behaviour on account of their frequent occurrence, their survival value, and the variety of the mechanisms involved. Many species regularly rely on their ability to home or reach other familiar sites, but how they manage to do this is often uncertain. In many cases the goal is attained in the absence of any sensory contact, by mechanisms of indirect orientation whose complexity and sophistication have for a long time challenged the skill and patience of many researchers. A series of problems of increasing difficulty have to be overcome; researchers have to discover the nature of orienting cues, the sensory windows involved, the role of inherited and acquired information, and, eventually, how the central mechanisms process information and control motory responses. Naturally, this book emphasizes targets achieved rather than areas unexplored and mysteries unsolved. Even so, the reader will quickly realize that our knowledge of phenomena and mechanisms has progressed to different degrees in different animal groups, ranging from the mere description of homing behaviour to a satisfactory insight into some underlying mechanisms. In the last few dacades there have been promising developments in the study of animal homing, since new approaches have been tried out, and new species and groups have been investigated. Despite this, homing phenomena have not recently been the object of exhaustive reviews and there is a tendency for them to be neglected in general treatises on animal behaviour.

Download or read book Sensory Processing in Aquatic Environments written by Shaun P. Collin and published by Springer Science & Business Media. This book was released on 2003-02-06 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on aquatic sensory processing -- the way animals see, hear, smell, taste, feel, and electrically and magnetically sense their environment -- has advanced a great deal over the last fifteen years. This book discusses the most recent and important themes that have emerged from research in the areas of neurobiology and sensory physiology. The layout of the book is arranged by function or task, rather than by a description of each sensory modality in turn. Part I, "Navigation and Communication," chiefly examines long-range sensory tasks, while "Finding Food and Other Localized Sources" (Part II) scales down to concentrate on more close-range processing. Part III, "Coevolution of Signal and Sense," describes the strong linkages between the physical parameters of the aquatic realm and the sensory receptors. Organisms living in light-limited environments have received a lot of recent attention, so Part IV gives special focus to visual adaptations in the deep sea. The final Part V, "Central Coordination and Evolution of Sensory Inputs," describes aspects of how signals are processed and filtered in the central nervous system. This book will be essential reading for all undergraduate and graduate students interested in aquatic biological sciences as well as for any researcher in sensory systems.
