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.
This volume is an outcome of the annual meeting of the crustacean society symposia on Crustacean Issues 2. It examines issues in contemporary carcinology. The volume emphasises on larval and postlarval growth in decapods.

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.
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.
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.
The authors are two of the best taxonomic experts in crustacean decapods, who have established the actual taxonomy and systematic of numerous and important groups of decapods. They have introduced new views and approaches on the taxonomy, phylogeny and biogeography of these crustaceans. This international edition adds diagnoses and identification keys to all world families and genera: this information simply doesn't exist in any other book. During the last decade, the world register of marine species (WORMS) has created the list of known species and promoted the publication of numerous compilations on crustacean decapods. However, except specialists of each taxa, very few colleagues can identify correctly the new families and genera - there are no keys to these new groups. This book is the first to contain these world keys and is therefore a life rope for students, marine biologists, taxonomists and naturalists. The mixture of taxonomic line drawings, color illustrations and images of real-life specimens is extremely helpful for identification, especially when working in the field.
This book offers the first comprehensive review of parasitic Crustacea, which are among the most successful and diverse parasites. Starting with an introductory chapter, followed by an historic overview and topic-specific chapters, each presenting a different aspect of parasitic crustacean biology, it enables readers to gain a better understanding of how these parasites function and allows direct comparisons between the different parasitic crustacean groups. The authors also discuss, in depth, the adaptations and interactions that have made parasitic Crustacea as successful as they are today, covering topics ranging from the history of their discovery, their biodiversity, phylogeny, evolution and life strategies to their role as vectors, or hosts of other organisms, and their significance in ecological processes. Consisting of ten chapters from leading international experts in the field, this volume offers a one-stop resource for all researchers, lecturers, students and practitioners.
This volume critically reviews all previously published work of parasites that interact with krill (order Euphausiacea) updating misconceptions and summarizing the diversity of epibionts, ectoparasites, mesoparasites and endoparasites that interact with these crustaceans. As far as we know, there is a lack of books about parasites of marine crustaceans not targeted to fisheries and aquaculture. Thus, this would be the most complete and integrative monograph of parasites of marine zooplankton and micro nektonic organisms worldwide. Krill form immense aggregations and serve as food for multiple planktonic and nektonic predators playing a crucial role in pelagic food web. Besides, several species are also used for human consumption. For these reasons there is a growing concern about the health issues that krill parasites may impose on other species, including us. This book provides a comprehensive review of parasites of a crustacean order that can extrapolate to potential parasites in other crustacean taxa worldwide.
This work provides a user-friendly, species level taxonomic key based on morphology, current nomenclature, and modern taxonomy using molecular tools which fulfill the most pressing needs of both researchers and environmental managers. This key arms the reader with the tools necessary to improve their species identification abilities. This book resolves another issue as well: the mix of female and male characters used in keys to the calanoid copepods. Often, during the identification process, both calanoid copepod sexes are not available, and the user of such a key is stuck with an uncertain identification. Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.
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.
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.
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 intervening years have plainly been productive ones for the field; indeed, I can only hope that there is no causal connection between its properity and my absence. Discontinuous contact with an intellectual venture, whatever disappointments it may present. does oifer one virtue; it provides a nwre dramatic. alnwst stroboscopic view of progress. To the lapsed practitioner, the rate of advance in crustacean neurobiology over the decade seems remarkable; equally remarkable is the number of able young researchers. many of them the scientific progeny of my colleagues from the "sixties" and "seventies" . How to summarize the changes they have wrought? Those of us who began working with crustacean nervous systems thirty years 090 or so were attracted by several features. First of alt there was a limited nwtor system with readily identifiable neurons. It was diJft.cult to look at those old methylene blue stains of Retzius and not want to do an experiment immediately! Kees Wiersma ojten did, and it was he who nwst persuasively called our attention to the advantages oifered by neuronal parsinwny in combination with stereotyped motor output patterning. Ted Bullock exploited these features in his elegant early experiments on cardiac ganglia.
This book contains excellent reviews on significant topics in crustacean neurobiology, introductory texts for classroom usage, examples for exciting original research, an account of a new research strategy and a new concept for teaching the principles of neuroscience, all written by renowned scientists from all over the world. In short, exciting reading for every neurobiologist.
Limulus in the Limelight: A Species 350 Million Years in the Making and in Peril? contains 14 chapters covering the horseshoe crab's biology, ecology and evolutionary development. The book is a result of three mini-conferences held between 1996 and 2000 celebrating the populations in NY harbor. This book exposes the impacts of over fishing on this species; clarifies the future research agenda for the species worldwide and emphasizes the need for conservation of this fascinating creature's estuaries/ocean habitats. Biologists, ecologists, science educators, and conservationists will welcome this book because it is aimed at the preservation of Limulus, not only for its pharmacological interest but for the mystery related to its longevity. Limulus is a unique animal which has provided numerous uses for man over the years, from fertilizer to bait to medical research. However, if this species is not protected soon, it will be lost for the future.
This unique selection of reviews summarizes current knowledge in all major fields of crustacean neurobiology and all levels of their CNS organization, using lobster and crayfish. It not only imparts theoretical knowledge but also describes all available contemporary and advanced techniques, such as patch clamp recordings, microelectrode techniques, immunocytochemistry, and all methods of molecular genetics to identify cellular pathways of protein synthesis and peptidergic control. In summary, it is a comprehensive account of the research achievements in one of the major nervous systems besides the mammalian CNS.
Ostracoda (Crustacea) are potentially excellent model organisms for evolutionary studies, because they combine an extensive fossil record with a wide recent distribution and therefore allow studies on both patterns and processes leading to extant diversity. The main scientific domains contributing theories, concepts, and data to evolutionary biology are morphology (including ontogeny), palaeontology, genetics, and ecology, and to all of these aspects ostracods can contribute. This is clearly illustrated by the fifteen papers presented under Theme 3 of the 13th International Symposium on Ostracoda (Chatham, UK) in 1997 which are grouped in the present proceedings, one of three volumes resulting from this meeting. The contributions deal with the evolution of both extant and fossil forms (including most of the Phanaerozoic), ecology of both marine and freshwater taxa, and (developmental) morphology of both soft parts and valves. Although the canvas is wide, each paper clearly shows how studies on Ostracoda can be relevant to general theory on evolutionary biology and ecology.
This volume is a collection of papers concerning the biology of large branchiopod crustaceans: Anostraca, Conchostraca, and Notostraca. Many of the individual papers were first presented at the Third International Large Branchiopod Symposium (ILBS-3) held at the University of San Diego, CA, USA, July 15-18, 1996. Contributions on additional topics from participants at the symposium, and from colleagues not able to join us in San Diego, are also included. In addition, there is a supplement to the 1995 Checklist of the Anostraca'. The theme of the ILBS-3 was understanding and conserving large branchiopod diversity'. Researchers from around the world presented papers on a variety of topics related to conservation of large branchiopods, with contributions ranging from alpha-taxonomy and zoogeography to community structure and studies of ecology and evolution. One important issue developed in many of the papers in this volume is the need to advance our understanding of basic aspects of branchiopod biology throughout the world in order to enhance our efforts to conserve them. Although we have made important strides in understanding the biology of large branchiopods, we have, with few notable exceptions, made little progress in assuring the conservation of their diversity. We hope this volume will supply the reader with new ideas, and generate enthusiasm for research and public education efforts on behalf of branchiopod conservation.
Fishermen, marine aquarists, biologists studying seashore and coastal waters, and those involved in trading shellfish and even restaurateurs are aware of the great diversity of crustaceans inhabiting the seas around the British Isles, Northern Europe and the Mediterranean. Crayfishes, Lobsters and Crabs of Europe will enable the reader to identify 42 crustacean species of commercial importance found in these regions during coastal explorations, fishing trips, displayed in public aquaria or available in restaurants, including selected freshwater crayfishes, deep-sea species and some imported species. The book also includes sections on the gross internal and external structure of these Crustacea, their life histories, classification and nomenclature. The book is of interest to students of marine biology and researchers in fisheries science.
Diapause is an event of great ecological significance in the lives of a wide range of invertebrates. The underlying physiological and genetic mechanisms pose many intriguing questions and have important evolutionary implications. Some of the most dramatic examples of diapause are provided by crustaceans. Most branchiopods produce resting eggs that can withstand intense desiccation and extremes of temperature and pressure far beyond those to which they are ever subjected in nature. Furthermore they can remain in a dry condition, displaying no measurable metabolism, for many years. Such abilities enable them to inhabit infrequently-filled pools in arid regions. When the pools fill with water these dormant eggs hatch and give rise to animals that grow quickly to maturity and produce a new generation of resting eggs. There is every reason to believe that primitive branchiopods have employed diapause in this way since Palaeozoic times and that their abilities in this direction have played a key role in their continued success as freshwater animals.
The Third International Symposium on Cladocera, papers from which make up this volume, covered recent findings on the behaviour, life history, population genetics, reproduction, chemical communication, predator-prey interactions, epibionts, taxonomy, phylogeny, palaeolimnology and biogeography of this animal group. The Cladocera occupy an intermediate position in lake ecosystems, both as plankton and benthic organisms. Their often high abundance and their function, as transfer organisms from algae and dead organic matter to macro-invertebrates and fish, make them one of the most important organisms to affect the biological processes in freshwater ecosystems. The Cladocera living among the plankton often have recognizable distribution patterns and migrations; their size and brief life cycles make them popular in laboratory experiments; their cyclic parthenogenesis makes them suitable for many aspects of population genetics; and they are present as microfossils in lake sediments. All these features confer a unique status on the Cladocera as model organisms in many aspects of modern systematics and ecology.
Ecology and Morphology of Copepods is organized under the following general topics: Behavior, Feeding, Genetics, Horizontal Variations, Morphology, Phylogeny, Reproduction, Seasonal Changes, Vertical Distribution, plus two special sessions on copepods of the genus Acartia and cyclopid/mosquito interactions. The Maxilliped Lecture, given by Dr. Arthur G. Humes of Boston University, clearly established the importance of copepods to the earth's organic diversity. The book consists of selected research articles from the different sections. The articles published here reflect the diverse research interests of copepodologists today, and are distinguished by their high quality. Their impact will ensure that this volume is consulted by a wide range of research biologists.
A great deal is now known about the functional organization, physiology, reproduction, and development of barnacles. For the first time, this book brings to bear all aspects of this knowledge on our interpretation of the dynamics of barnacle evolution relating them to the fossil history and biogeography of the group. |
