This book was released on 1967 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: An examination was made of fresh and preserved specimens of Pacific lantern fishes, hatchet fishes, and hake. Most of the lantern fishes under 50-mm standard length contain gas in their swimbladders and, hence, are probably major sound scatterers. The hatchet fishes possibly contribute to scattering of nonmigratory layers. The resonance depths of the swimbladders differ widely for sound of different frequencies. Because of its larger size, the swimbladder of the hake should resonate at low frequencies.

Book Synopsis A Review of the World Resources of Mesopelagic Fish by : J. Gjøsaeter
Download or read book A Review of the World Resources of Mesopelagic Fish written by J. Gjøsaeter and published by Food & Agriculture Org.. This book was released on 1980 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fish species can be called mesopelagic if it spends the day in the mesopelagic zone. The mesopelagic zone has been defined in different ways based on depth, temperature and light regimes. For the present purpose, depth seems to be the best criterion and mesopelagic fish can thus be defined as species generally spending the day at depths between approximately 200 and 1 000 m. Generally they perform a diel migration, coming to the upper 200 m or even to the surface during the night. The present report briefly reviews the systematics ecology and life history of important groups of mesopelagic fish. Further, some methods used for abundance estimation of these fish are described and discussed. The bulk of the report reviews the present knowledge of abundance and species composition of mesopelagic fish in each of the FAO statistical areas. Although the data in most cases are few, an attempt has been made to give tentative estimates of the biomass and production in the various areas. When available, information on the life history of the most important species in each area is also given.

Available in PDF, EPUB and Kindle. Book excerpt: “A masterful accomplishment—Allen, Pondella and Horn have assembled a talented team of experts who produce authoritative, up-to-date accounts. This book will be used as the primary text in many fish biology courses and as a valuable reference elsewhere. Here is a wealth of data waiting to be mined by legions of graduate students as they generate the new ideas that will motivate marine ecology for years.”—Peter Sale, Editor of Coral Reef Fishes: Dynamics and Diversity in a Complex Ecosystem "A copiously illustrated and comprehensive interpretation of the past, present, and future state of over 500 species of fishes in Californian waters. A compilation of virtually all the many important studies on the ecology of California marine fishes."—Bruce B. Collette, National Marine Fisheries Service and co-author of The Diversity of Fishes

Book Synopsis Underwater Physiology by : C. J. Lambertsen
Download or read book Underwater Physiology written by C. J. Lambertsen and published by Academic Press. This book was released on 2013-10-22 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underwater Physiology is a collection of papers that deals with the physiologically limiting effects of undersea, high pressure exposure ranging from fundamental biological reactions, through integration of physiological stresses, and to limits actually experienced in deep diving. Papers discuss oxygen, the mechanisms of toxicity, and the effects of oxygen on cells and systems such as its pathological and physiological influences in the neurosensory ocular tissue. Other papers discuss the physical effects of pressure and gases on cellular function, protein structure, and the possibility of alleviating symptoms through the administration of drugs. Tests in mice show that various gases exhibit qualitative and semi-quantitative differences in the characteristics of sickness, reactions to hypoxia, and the time before the onset of symptoms. A computer, programmed for nonlinear gas transfer and other variables, running in real time can compute directly from the breathing mixture and provide a real time solution to decompression sickness under various conditions. A combined therapeutic approach, recompression and dextran (an effective lipemic clearing agent) should be capable of treating decompression sickness in humans. Other papers investigate the influence of inert gases and pressure on the central nervous system, as well as, situations in undersea and manned chamber operations. This collection can prove valuable for physiologists, biochemists, cellular biologists, and researchers involved in deep sea diving.

Book Synopsis Principles of Animal Locomotion by : R. McNeill Alexander
Download or read book Principles of Animal Locomotion written by R. McNeill Alexander and published by Princeton University Press. This book was released on 2013-10-31 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can geckoes walk on the ceiling and basilisk lizards run over water? What are the aerodynamic effects that enable small insects to fly? What are the relative merits of squids' jet-propelled swimming and fishes' tail-powered swimming? Why do horses change gait as they increase speed? What determines our own vertical leap? Recent technical advances have greatly increased researchers' ability to answer these questions with certainty and in detail. This text provides an up-to-date overview of how animals run, walk, jump, crawl, swim, soar, hover, and fly. Excluding only the tiny creatures that use cilia, it covers all animals that power their movements with muscle--from roundworms to whales, clams to elephants, and gnats to albatrosses. The introduction sets out the general rules governing all modes of animal locomotion and considers the performance criteria--such as speed, endurance, and economy--that have shaped their selection. It introduces energetics and optimality as basic principles. The text then tackles each of the major modes by which animals move on land, in water, and through air. It explains the mechanisms involved and the physical and biological forces shaping those mechanisms, paying particular attention to energy costs. Focusing on general principles but extensively discussing a wide variety of individual cases, this is a superb synthesis of current knowledge about animal locomotion. It will be enormously useful to advanced undergraduates, graduate students, and a range of professional biologists, physicists, and engineers.
