Download or read book Octopus Biology and Ecology written by Rui Rosa and published by Academic Press. This book was released on 2024-06-03 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Octopus Biology and Ecology is an all-in-one resource that explains early life history stages, including age and growth maturation, distribution, migration, diet, predators and parasites related to these mollusks. Octopods are becoming a strong source of protein, with information on the species becoming more and more important to fisheries. This reference offers detailed information on the most economically important octopods in the world and addresses the management and future forecasting of octopod fisheries. Special attention is given to octopods in highly variable coastal environments as they constitute a particular challenge. Octopod populations (together with other cephalopod groups) have increased worldwide, suggesting that these commercially relevant mollusks will benefit from the conditions of the oceans of tomorrow (e.g., global warming and decreased competition and predator pressures). This is a complete resource for aquatic scientists, marine biologists, researchers, cephalopod biologists, cephalopod ecologists, fisheries and aquaculture scientists, regulators and students. ? Provides a thorough overview of the biodiversity of octopuses? Presents detailed information about 21 different species? Includes a profound analysis of past, present, and future trends in octopus research

Download or read book Chemical Communication in Crustaceans written by Thomas Breithaupt and published by Springer Science & Business Media. This book was released on 2010-11-25 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crustaceans are ecologically and economically important organisms. They constitute one of the dominant invertebrate groups on earth, particularly within the aquatic realm. Crustaceans include some of the preferred scientific model organism, profitable aquaculture specimen, but also invasive nuisance species threatening native animal communities throughout the world. Chemoreception is the most important sensory modality of crustaceans, acquiring important information about their environment and picking up the chemical signals that mediate communication with conspecifics. Significant advances have been made in our understanding of crustacean chemical communication during the past decade. This includes knowledge about the identity, production, transfer, reception and behavioral function of chemical signals in selected crustacean groups. While it is well known that chemical communication is an integral part of the behavioral ecology of most living organisms, the intricate ways in which organisms allocate chemicals in communication remains enigmatic. How does the environment influence the evolution of chemical communication? What are the environmental cues that induce production or release of chemicals? How do individuals economize production and utilization of chemicals? What is the importance of molecule specificity or mix of a molecule cocktail in chemical communication? What is the role of chemical cues in multimodal communication? How does the ontogenetic stage, the sex or the physiological status of an individual affect its reaction to chemical cues? Many of these questions still represent important challenges to biologists.

Download or read book The Biology and Management of Lobsters written by J. Stanley Cobb and published by Elsevier. This book was released on 2012-12-02 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work presents a summary and review of the current state of lobster biology, ecology, physiology, behavior, and management. It emphasizes the biology of clawed lobsters (Nephropidae) and spiny lobsters (Palinuridae), with attention also given to slipper lobsters (Scyllaridae) and coral lobsters (Synaxidae).The first chapter of Volume 1 provides an overview of the general aspects of lobster biology that serves as an introduction for readers of both volumes. Subsequent chapters examine the topics of growth, neurobiology, reproduction, nutrition, pathology, social behavior, and migration patterns.The chapters in Volume II consider the ecology, population dynamics, fishery biology, and aquaculture of spiny and clawed lobsters. The topics selected in both volumes represent areas of current research whose findings have not been previously synthesized into a coherent form.An important feature of these volumes is the emphasis on the interaction between biology and management and culture. Many of the contributors have done research in both applied and basic biology and can articulate both points of view. The interaction between basic and applied research is of fundamental importance in these volumes in which management aspects of the research have been integrated with the basic biology of lobsters.The Biology and Management of Lobsterswill be of interest to crustacean biologists, marine biologists and ecologists, zoologists, physiologists, animal behavior researchers, aquaculturalists, fisheries biologists and managers of fisheries, neurobiologists, pathologists, and food scientists.

Download or read book Regional Fisheries Oceanography of the California Current System written by Sam McClatchie and published by Springer Science & Business Media. This book was released on 2013-09-30 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The California Current System is one of the best studied ocean regions of the world, and the level of oceanographic information available is perhaps only surpassed by the northeast and northwest Atlantic. The current literature (later than 1993) offers no comprehensive, integrated review of the regional fisheries oceanography of the California Current System. This volume summarizes information of more than 60-year California Cooperative Oceanic Fisheries Investigation (CalCOFI). While providing a large bibliography, the intent was to extract themes relevant to current research rather than to prepare a compendious review of the literature. The work presents a useful review and reference point for multidisciplinary fisheries scientists and biological oceanographers new to working in the California Current System, and to specialists wishing to access information outside their core areas of expertise. In addition it aims to deliver an up to date reference to the current state of knowledge of fisheries oceanography in the California Current System.

Download or read book Coral Reefs and Climate Change written by Jonathan Turnbull Phinney and published by American Geophysical Union. This book was released on 2006-01-10 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 61. The effects of increased atmospheric carbon dioxide and related climate change on shallow coral reefs are gaining considerable attention for scientific and economic reasons worldwide. Although increased scientific research has improved our understanding of the response of coral reefs to climate change, we still lack key information that can help guide reef management. Research and monitoring of coral reef ecosystems over the past few decades have documented two major threats related to increasing concentrations of atmospheric CO2: (1) increased sea surface temperatures and (2) increased seawater acidity (lower pH). Higher atmospheric CO2 levels have resulted in rising sea surface temperatures and proven to be an acute threat to corals and other reef-dwelling organisms. Short periods (days) of elevated sea surface temperatures by as little as 1–2°C above the normal maximum temperature has led to more frequent and more widespread episodes of coral bleaching-the expulsion of symbiotic algae. A more chronic consequence of increasing atmospheric CO2 is the lowering of pH of surface waters, which affects the rate at which corals and other reef organisms secrete and build their calcium carbonate skeletons. Average pH of the surface ocean has already decreased by an estimated 0.1 unit since preindustrial times, and will continue to decline in concert with rising atmospheric CO2. These climate-related Stressors combined with other direct anthropogenic assaults, such as overfishing and pollution, weaken reef organisms and increase their susceptibility to disease.

Download or read book Mechanisms of Migration in Fishes written by James D. McCleave and published by Springer Science & Business Media. 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.

Download or read book Quantitative Fisheries Stock Assessment written by R. Hilborn and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book really began in 1980 with our first microcomputer, an Apple II +. The great value of the Apple II + was that we could take the computer programs we had been building on mainframe and mini-computers, and make them available to the many fisheries biologists who also had Apple II + 's. About 6 months after we got our first Apple, John Glaister came through Vancouver and saw what we were doing and realized that his agency (New South Wales State Fisheries) had the same equipment and could run the same programs. John organized a training course in Australia where we showed about 25 Australian fisheries biologists how to use microcomputers to do many standard fisheries analyses. In the process of organizing this and sub sequent courses we developed a series of lecture notes. Over the last 10 years these notes have evolved into the chapters of this book.

Download or read book Advances in Aquaculture Hatchery Technology written by Geoff Allan and published by Elsevier. This book was released on 2013-02-19 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture is the fastest-growing food production sector in the world. With demand for seafood increasing at astonishing rates, the optimization of production methods is vital. One of the primary restrictions to continued growth is the supply of juveniles from hatcheries. Addressing these constraints, Advances in aquaculture hatchery technology provides a comprehensive, systematic guide to the use of current and emerging technologies in enhancing hatchery production.Part one reviews reproduction and larval rearing. Aquaculture hatchery water supply and treatment systems, principles of finfish broodstock management, genome preservation, and varied aspects of nutrition and feeding are discussed in addition to larval health management and microbial management for bacterial pathogen control. Closing the life-cycle and overcoming challenges in hatchery production for selected invertebrate species are the focus of part two, and advances in hatchery technology for spiny lobsters, shrimp, blue mussel, sea cucumbers and cephalopods are all discussed. Part three concentrates on challenges and successes in closing the life-cycle and hatchery production for selected fish species, including tuna, striped catfish, meagre, and yellowtail kingfish. Finally, part four explores aquaculture hatcheries for conservation and education.With its distinguished editors and international team of expert contributors, Advances in aquaculture hatchery technology is an authoritative review of the field for hatchery operators, scientists, marine conservators and educators. - Provides a comprehensive guide to the use of technologies in enhancing hatchery production - Examines reproduction and larval rearing, including genetic improvement and microdiets - Discusses challenges in hatchery production of specific species

Download or read book Upwelling Ecosystems written by R. Boje and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upwelling areas are among the most fertile regions of the ocean. In principle, upwelling is caused by the divergence of the flow in the surface layer of the ocean which arises as a consequence of a particular wind field, the presence of a coastline, or other special conditions. Since deeper oceanic layers are usually enriched wi th nutrients, it is the permanent supply of nutrients which forms the basis for the high producti vi ty of upwelling reg ions. The study of upwelling and its consequences were, for a long time, the task of individual scientists from all disciplines of marine science. Today, it is perhaps the branch of oceanography where interdisciplinary coopera tion has developed best. Becoming aware of the large potential yield of upwelling regions, governments in creased the funds for upwelling research. With research activities developed on a larger scale, interdisciplin ary cooperation became a necessity. On the international level, several symposia documented the rapid development. Three volumes reflect the results of these scientific meetings (Rapp. Proc.-Verb. 159, 1970; Inv. Pesq. 35, 1, 1971; Tethys §.' 1-2, 1974). The present book contains selected papers from the Third Symposium on Upwelling Ecosystems, which was held in Kiel in September 1975. Although the third of a series of meetings, it was the first where the word "ecosystem" stood in the title for a scientific program.
