This volume is an outcome of the symposia on the Crustacean Issues in the annual meeting of The Crustacean Society. It examines in depth timely topics at issue in contemporary carcinology. The volume covers studies of growth rate and life history in two of the major categories of crustaceans.

This book discusses the nutritional requirements, physiology, and diseases of prawn, and analyzes the contents of various techniques of prawn culture and the related problems, so as to help prawn culture to progress and to increase the production rate.

For their great commercial importance as a human food delicacy, crayfish are now becoming of wider interest to molecular biologists, and also to conservationists due to the fact that in some countries many of the native crayfish species are under threat from human activity, disease, and competition from other introduced crayfish species. Helmed by three editors in Japan, Europe, and the US, this book invites contributions from experts around the globe, covering the conservation status and biology of all endangered species, taxonomy, and distribution of crayfishes worldwide.

With species existing in all subpolar seas, king crabs are one of the most valuable seafoods. Major fluctuations in their abundance have stimulated a flurry of research and a rapid expansion of the scientific literature in the last decade. King Crabs of the World: Biology and Fisheries Management consolidates extensive knowledge on the biology, systematics, anatomy, life history, and fisheries of king crabs and presents it in a single volume. This book is the first comprehensive scientific reference devoted to the biology and fisheries of king crabs.
The first part of the book describes king crabs and their place in the world, covering geographic distribution, depth and temperature ranges, and maps of known habitats. Chapters examine phylogenetic relationships, evolutionary history and phylogeography, internal and external anatomy of king crabs, and the history of North Pacific fisheries. There is also a chapter that presents a comprehensive overview of diseases and other anomalies of king crabs. The second part of the book describes the life history and biology of various king crab species, including embryonic development and environmental factors, the development and biology of larvae, the ecology and biology of juvenile stages, reproductive strategies of fished species, and the growth and feeding of king crabs and their ecological impacts.
The third part of the book discusses human and environmental interactions with king crabs through fisheries, management, and ecosystems. Topics include the impacts of fishing bycatch, handling, and discard mortality king crab aquaculture and stock enhancement, and king crabs from various regions such as Southern Hemisphere waters, the Barents Sea, and Alaska. A chapter synthesizing various aspects of king crab biology provides an ecosystem-scale perspective and the final chapter presents the author s outlook on the future of king crab research and populations."

Covers all the main aspects of crustacean biology and ecology. Explains the main ethology issues also in view of applicative purposes. Is oriented to aquaculture, biofouling and parasitology biotechnologies. Covers both theoretical and practical issues. Is authored by a select list of outstanding world experts.

Written by international experts, The Biology and Fisheries of the Slipper Lobster provides comprehensive coverage of the known biology, ecology, behavior, physiology, evolutionary history, and genetics of the numerous species in the family Scyllaridae. It covers fishing methods and regulations, size and composition of catches, fisheries management, and distribution of those particular species that are targeted species or by-products of other fisheries. The book takes a comparative approach to understanding fisheries in different regions of the world and examines management plans that have failed and those that have succeeded.

For the first time in limnofaunistic bibliography, the present taxonomic knowledge about the different clades of chelicerata having adapted to an aquatic or amphibious lifestyle along various evolutionary pathways is brought together in an overview for the Central-European fauna. A total number of 746 taxa is covered, over 99 % of these at species level. In Volume 7/2-1 altogether 211 species are treated - 70 species of spiders, 7 species of Astigmata (3 of which to be identified only at family, genus, resp. species group level), 17 species of Oribatida, 27 species and one subspecies of Halacaridae, 45 species of terrestrial Parasitengona (4 of which to be identified only at genus level) and 45 species of Hydrachnidia (4 Stygothrombioidea, 3 Hydrovolzioidea, 16 Hydrachnoidea and 22 Eylaoidea). Volume 7/2-2 deals with 179 species of Hydrachnidia (58 Hydryphantoidea and 121 Lebertioidea). This third volume (Volume 7/2-3) includes taxonomic keys and ecological information for 355 species of the two highly diverse Hydrachnidia superfamilies Hygrobatoidea (241 species and one subspecies) and Arrenuroidea (113 species). The chelicerata volumes of this series are a basic tool for all limnologists interested in diversity and ecology - in particular for biologists investigating the ecotones between ground and surface water, between bottom substrata and open water, and between water and land.

Compared to other arthropods, crustaceans are characterized by an unparalleled disparity of body plans. Traditionally, the specialization of arthropod segments and appendages into distinct body regions has served as a convenient basis for higher classification; however, many relationships within the phylum Arthropoda still remain controversial. Can Crustacea even be considered a monophyletic group? If so, then which are their closest relatives within the Arthropoda? The answers to questions such as these will play a key role in understanding patterns and processes in arthropod evolution, including the disappearance of certain body plans from the fossil record, as well as incidences of transition from aquatic to terrestrial environments. Crustacea and Arthropod Relationships, written by a team of internationally recognized experts, presents a wide variety of viewpoints, while offering an up-to-date summary of recent progress across several disciplines. With rich detail and vibrancy, it addresses the evolution and phylogenetic relationships of the Arthropoda based upon molecular, developmental, morphological, and paleontological evidence. Volume 16 is the first in the series to not be exclusively dedicated to discussions specific to crustaceans. While it is still crustaceo-centric, the focus of this volume has been extended to include other groups of arthropods along with the Crustacea. This wider focus offers challenging opportunities to evaluate higher-level relationships within the Arthropoda from a carcinologic perspective. This volume is dedicated to the career of Frederick R. Schram, the founding editor of CrustaceanIssues in 1983, in recognition of his many stimulating and wide-ranging contributions to the evolutionary biology of arthropods in general, and of crustaceans in particular.

Donald Kennedy President, Stanjord University Alnwst exactly a dozen years elapsed between the time I set aside (I thought temporarily!J my own interest in crustacean nervous systems and the arrival of an invitation from Konrad Wiese to participate in this symposium.

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.

Their story began 500 million years ago, but we only started to get to know them in 1746, when Linne described the first ostracod species. Vividly portraying the freshwater ostracods, this comprehensive reference work gathers the knowledge gained during some 250 years, but which to date has remained scattered throughout the literature. It starts with an introduction to the class Ostracoda with a special focus on freshwater ostracods and highlights practical methods in their study. The systematic part includes an introduction to all families; identification keys for all subfamilies, genera and species; diagnoses for each subfamily and genus; and lists of synonyms and distribution of species. The text is richly illustrated with distribution maps, line drawings of key generic characteristics, and numerous SEM photographs. Serving as an excellent starting point for all further research on freshwater ostracods, it can be widely used not only by ostracodologists, but also by crustaceologists, evolutionists and ecologists.

A richly illustrated natural history of the world's crabs that examines their diversity, ecology, anatomy, behavior, and more This lavishly illustrated book offers a remarkable look at the world's crabs. More than 7,000 crab species, in 100 different families, are known today. Their unique physiology and complex behaviors have made them one of the most diverse and adaptable of all animal groups. They can thrive in the darkness of abyssal seas, on the edges of scalding hot volcanic hydrothermal vents, on sunlit coral reefs, on wave-washed rocky shores, and in tropical rain forests at the tops of mountains. They even persist in some of the harshest desert conditions. Playing a vital role in marine and coastal ecology, crabs have been identified as keystone species in habitats such as coral reefs and coastal tropical swamps. Crabs comprises five chapters: evolutionary pathways; anatomy and physiology; ecology; reproduction, cognition, and behavior; and exploitation and conservation. Individual chapters include a variety of subtopics, each illustrated by exceptional images, and followed by numerous double full-page species' profiles. Each profile has been chosen to emphasize remarkable and intriguing aspects of the life of these fascinating creatures. Some species may be familiar, but many are beyond anything you have probably seen before and will stretch your understanding of what a crab is. Written by a world authority, Crabs offers an accessible overview of these fascinating crustaceans. More than 190 spectacular color photographs Accessible and well-organized chapters Full profiles on 42 iconic species from across the world

In August 1988. the Sixth International Coral Reef Symposium was held in Townsville resulting in an influx of most of the world's coral reef sCientists to the city. We seized this opportunity at the Australian Institute of Marine Science to run a small workshop immediately before the symposium on the outbreaks of the crown-of-thorns starfish. Aeanthaster planei. We invited that small band of mathematicians who had been modelling the phenomenon, (and who may not have normally attended an international meeting so thoroughly dedicated to natural science) to meet with those SCientists who had been been actively working on the phenomenon in the field. John Casti notes in his delightful new book Alternate Realities (Wiley, 1989): 'If the natural role of the experimenter is to generate new observables by which we know the processes of Nature, and the natural role of the mathematician is to generate new formal structures by which we can represent these processes. then the system SCientist finds his niche by serving as a broker between the two. ' I think our book shows the fruits of that brokerage through the wide range of models explored within its pages. the high level of collaboration and interaction across disciplines evident in the individual papers, and in the emerging synthesis that reflects a far deeper understanding of this complex phenomenon than was possible even a few years ago.

This volume provides an abundance of valuable first-hand information about the diversity, biology, ecology culture of the portunid crabs of the word seas. Marine crabs play an important role directly or indirectly in the livelihood of millions of people around the world. They have been reported to make up about 20% of all marine crustaceans caught, farmed, and consumed worldwide. Among these marine crabs, portunid crabs (or swimming crabs of the family Portunidae) assume greater significance in the marine industry, owing to their delicate meat with nutritional qualities. Although several species of portunid crabs are edible and commercially important, only a few species have been widely cultivated. This is largely due to the lack of information on the biology of portunid crabs. Keeping this in view, this volume presents the biology and aquaculture of marine portunid crabs. This volume will be of great use for researchers and students of disciplines such as fisheries science, marine biology, aquatic biology and fisheries, and zoology, and will also serve as a standard reference for college, university, and research libraries around the world.

The Zoological Guide to Crustacea opens by providing an update on the cave crustacean decapods from Mexico, because in the last thirty years several species have been described. Mexico has diverse cave environments according to cave origin, such as: karstic caves, volcano caves with freshwater habitats and anchialine caves with marine and brackish habitats. The following study focuses on a total of 2,700 Artemia franciscana collected at the Al Wathba Reserve between December 2017 and May 2018, which were examined for the presence of larval helminths by direct microscopy of glycerin mounted specimens. Of these, 341 (= 12.6%) specimens contained different species of the Hymenopepididae and Progynotaeniidae families. The penultimate study investigates whether the non-marine ostracod Heterocypris incongruens can detect and react to chemical compounds derived from a predator and from injured conspecifics. The closing study demonstrates the diversity of larval phases and their importance to lobster populations and fisheries, and provides a summary of larval developmental patterns and behaviors and their potential impacts on larval dispersal and lobster demographic connectivity.

This is a contribution to the conservation of members of the family Cambaridae. This book is focused on the evaluation of geographic changes caused by landscape scale and land use change that has impacted the ecology of North American crayfish species. The book includes chapters on geographic distributions, conservation strategies, and effects of contaminants on crayfish structure and function. Contributors include a variety of students associated with the Editor, as well as original contributions from the Editor's colleagues. From the conceptual frameworks to the case studies, Geographic Distribution, Ecological Impact, and Conservation Strategies for North American Crayfish will provide important considerations to assist in the conservation and protection of crayfish, with emphasis on stressors and actions necessary to protect and restore crayfish habitats and populations. This book is necessary for environmental and natural resource managers, researchers, and governmental agencies tasked with the protection, restoration, and management of wildlife populations.

The purpose of this book is twofold: on one hand, it gives a mathematical perspective of Daphnia which comprises studies focusing on introducing size-structured population dynamics models of Daphnia and their unification, as well as developing and analyzing mathematical models of size-structured population dynamics of several species of Daphnia. These include proving the well-posedness of the model and related regularity properties, determining the steady states and proving the principle of linearised stability and studying the (in)stability of the steady states. The mathematical perspective of Daphnia is written at a research level and it is intended for researchers in applied mathematics, differential equations, biomathematics, mathematical biology, mathematical ecology as well as graduate students in the above mentioned fields of research. The necessary background for reading the chapters is the knowledge of ordinary differential equations, partial differential equations, integral equations and functional analysis. On the other hand, this book also provides a biological perspective of Daphnia by focusing on topics such as: the swimming behaviour, inducible defense mechanisms in order to avoid predation, sexual reproduction, the use of Daphnia as a classroom organism and the role of Daphnia in ecotoxicological evaluations of contaminants. In addition, it contains several video movies attached to some chapters. The biological perspective of Daphnia is written at a research level and intended for researchers in biology, chemistry, ecology and environment as well as graduate students in the above-mentioned fields of research.

In this book, the authors discuss the structure, ecology and life cycle of crustaceans. Topics include the structure, development and evolution of crustacean eyes; the effect of gamma radiation on the extraction of chitosan from the exoskeleton of crustaceans; lipid transport and metabolism in crustaceans; and soft-bottom crustacean assemblages influenced by anthropogenic activities in the Arabian Gulf.

Terrestrial hermit crabs are among the most widespread beach-dwelling organisms with key ecological functions but receive only very limited research attention. Sebastian Steibl demonstrates how physical parameters shape their overall distribution, presents a possible mechanism for their speciation and coexistence and shows for the first time how different human activities can have a major impact on their populations. The author points out that terrestrial hermit crabs, due to their conspicuous behavior to utilize shells, are a good model to study mechanisms of competition and coexistence in natural populations. Furthermore, they are suitable indicator organisms to assess human impact, as they respond differently depending on the type of anthropogenic disturbance. About the Author: Sebastian Steibl is a PhD student at the Institute of Animal Ecology at the University of Bayreuth, Germany. In his actual PhD research, he builds up on the presented work to investigate the architecture as well as functionality of small insular ecosystems and to analyze how different anthropogenic disturbances impact those ecosystem processes.

This is the eighth volume of a ten-volume series on The Natural History of the Crustacea. The volume examines Evolution and Biogeography, and the first part of this volume is entirely dedicated to the explanation of the origins and successful establishment of the Crustacea in the oceans. In the second part of the book, the biogeography of the Crustacea is explored in order to infer how they conquered different biomes globally while adapting to a wide range of aquatic and terrestrial conditions. The final section examines more general patterns and processes, and the chapters offer useful insight into the future of crustaceans.

This second volume in the Natural History of the Crustacea series examines how crustaceans-the different body shapes and adaptations of which are described in volume 1-make a living in the wide range of environments they inhabit, and how they exploit food sources. The contributions in the volume give synthetic overviews of particular lifestyles and feeding mechanisms, and offer a fresh look at crustacean life styles through the technological tools that have been applied to recent crustacean research. These include SEM (scanning electron microscope) techniques, micro-optics, and long-term video recordings that have been used for a variety of behavioral studies. The audience will include not only crustacean biologists but evolutionary ecologists who want to understand the diversification of particular life styles, ecologists who follow the succession of communities, biogeochemists who estimate the role of crustaceans in geochemical fluxes, and biologists with a general interest in crustaceans.

Crustacean Nervous Systems and their Control of Behavior is the third volume of the series The Natural History of the Crustacea. This volume is on the functional organization of crustacean nervous systems, and how those nervous systems produce behavior. It complements other volumes on related topics of feeding biology, reproductive biology, endocrine systems, and behavioral ecology. There is a rich history of the study of the neurobiology of crustaceans, going back over 150 years. This has included studies on how their nervous systems allow them to perform behaviors that are adapted to their particular environments, as well as studying them as model organisms to understand basic biomedical principles about neural function, such as sensory transduction and processing, synaptic transmission and integration, neuromodulation, and learning and memory. The volume has three sections that build progressively on each other. The first section is on the basic organizational features of the crustacean nervous system and the principles upon which it is built. The second section is on sensory ecology - the organization of each sensory system and how it is used in intra- and interspecific interactions, within an ecological context. The third section uses case studies of how crustacean nervous systems are organized to perform complex behaviors and interactions, such as walking, escape, social interactions, and memory and learning. Taken together, the 20 chapters synthesize our modern understanding of the neural control of behavior in crustaceans, based on the most recent technologies in physiological recording, molecular biology, and computational science. This volume will be useful to students and researchers as a concise summary of current knowledge of crustacean neuroscience.
