Book Description
Crustaceans have become the most popular proteinacious foods to meet the food demand of ever growing human population in the World. But, the culturing of crustacean species has many problems, including limited availability of quality seed. Out of all conventional methods practiced to increase seed of good quality and quantity, manipulation of the endocrine system of brood stock is found to be one of the best methods. Regulation of crustacean reproduction is under the control of many hormones and factors. The eyestalk hormones, namely gonad/vitellogenin-inhibiting hormone (VIH) and mandibular organ inhibiting hormone (MOIH) show negative effects on maturation, whereas the other eyestalk hormones show mixed effects on maturation. The non-eyestalk hormones namely gonad stimulating hormone (GSH), methyl farnesoate (MF) and ecdysteroids are ovarian maturation inducers in crustaceans. The pros and cons of endocrine manipulation in crustaceans are discussed in this chapter.

Book Description
Sexual Biology and Reproduction in Crustaceans covers crustacean reproduction as it deals with the structural morphology of the gamete-producing primary sex organs, such as the testis and ovary, the formation and maturation of gametes, their fusion during fertilization, and embryonic development that lead to the release of larvae. Constituting a diverse assemblage of animals, crustaceans are best known by their common representatives, such as shrimps, lobsters, and crabs, but also include many more less familiar, but biologically important forms. This work covers the variety of ways in which both male and female gametes are produced by evolving different sexual systems in crustaceans, the range of reproductive systems, and the accordingly, and highly diverse, mechanistic modes of sex determination. In addition, the book features such topics as genetic and environmental determinants in sex determination pattern, variability of mechanisms of fertilization among different species, the origin of different mating systems, the associated mating and brooding behaviors, and the adaptive ability to different environmental conditions with discussion on the evolutionary ecology of social and sexual systems in certain species, which have shown eusocial tendencies, similar to social insects. Marine species occupying diversified ecological niches in tropical and temperate zones reproduce under definitive environmental conditions. Therefore, reproductive ecology of different crustaceans inhabiting different ecological niches also constitutes another important aspect of the work, along with yolk utilization and embryogenesis leading to release of different larval forms, which reflect on their aquatic adaptability. Forms a valuable source of recent references on the current research in crustacean reproductive physiology Covers various mating and breeding systems, providing illustrative examples for sexual selection, parental care of developing eggs and embryos, and the evolution of other reproductive behaviors Features contributions written in the form of review articles, enabling readers to not only gain information in the respective subject, but also help them stimulate ideas in their chosen field of research Includes a glossary created by the author to define technical terms Demonstrates the ability of crustacean species to serve as useful model systems for other organisms, to investigate issues related to sexual conflict, mate choice, and sperm competition Discusses techniques in endocrine research to help researchers in aquaculture develop protocols in the control of reproduction

Book Description
Anyone who attempts to study crustaceans soon realizes that there are many science fields involved. As a major subphylum of Arthropods—the largest phylum in the animal kingdom—crustaceans exhibit an extraordinary diversity of taxa, shapes, physiology and styles of life. These invertebrates play key ecological roles in all aquatic environments, while only a few species are adapted to sub-aerial and humid environments. Their evolutionary success is not only due to a wide set of morphological and biological adaptations, but also because of some key features, e.g., their peculiar endocrinology. In addition, crustaceans are characterized by chemical and optical sensors deserving attention because they play important biological roles, linked to chemical ecology issues, and their functioning is impaired by global changes and ocean acidification. Several crustaceans have critical roles in aquatic ecology (e.g., copepods in the plankton, amphipods and isopods in the benthos). Select species are technologically important as "models" for scientific research. Furthermore, aquaculture of several decapod crustaceans is important for providing high protein products to meet the need for nutrition. Understanding the physiology and ecology of crustaceans is important to fulfill these diverse purposes and practical applications. In this book, leading world scientists have pooled their excellence to provide vibrant and expert views of fundamental biological and physiological mechanisms involving crustaceans. To this end, a comprehensive view of crustacean endocrinology and reproductive ecology is provided, along with information about their molecular physiology, adaptations, aquaculture and welfare. In particular, we attempted to span the breadth of their adaptations, presenting behavioral and physiological peculiarities, considering key groups of crustaceans to describe general features and global biodiversity. This book is offered as a tool for students and scientists in various fields of physiological, ecological, biotechnological and aquacultural research.

Book Description
Demand for crustacean production is increasing significantly throughout the world, and crustacean production from capture fisheries has almost stagnated. Aquaculture is the only possibility to meet this ever-growing demand for crustaceans. Still, many commercially important crustaceans are being captured from the wild, while breeding and seed production technologies are not available for these species. The bottleneck in the successful breeding of crustacean species is mainly due to the non-availability of information about reproductive biology. Studies on crustacean reproduction will shed new light on understanding the mechanism of sex determination and differentiation; meanwhile, the application of innovative techniques will vitally contribute to the progress of the crustacean industry. The research findings on crustacean reproduction will directly benefit aquaculture for successful captive breeding and seed production. Here, we are gathering both original research and review papers with the scope of the research topic, including but not limited to: • Mechanism of sex determination, sexual differentiation, and gonadal development in crustaceans; • Other life functions (e.g. endocrine, nutrition, immunity, heredity) involved in reproduction in crustaceans; • Applications of modern endocrinological and molecular approaches contributed to crustacean reproduction.

Book Description
Comparative endocrinology is one of the most rapidly developing subdis ciplines within the field of endocrinology, and it is having a significant impact on research at the molecular, cellular, organisma1 and environmental levels. Much of the current ferment in endocrinology is in reproductive endocrinology. The purpose of this volume on hormones and reproduction in fishes, amphibians and reptiles is to summarize our present understandings and to identify important research problems to be addressed in the area of comparative reproductive endocrinology. It was inspired by the gathering at Copper Mountain, Colorado, of eminent endocrine scientists from around the world on the occasion of the Tenth International Symposium on Comparative Endocrinology in July, 1985. While preparing for that meeting, we decided that a special volume on reproductive endocrinology was needed to summarize what is known and to stimulate research in particular directions. Why do we emphasize fishes, amphibians and reptiles? First, knowledge about the reproductive endocrinology of these ectothermic vertebrates can provide a clearer picture of the evolution of reproductive hormones and their effects on target organs. This comparative approach can lead to new theories about the evolution of reproductive control mechanisms. Second, studies concerning the reproductive endocrinology of "lower" vertebrates can result in development of "model systems" for application to studies of birds and mammals. Indeed, information about the patterns of reproductive control in ectothermic vertebrates can tell us which are evolutionarily stable and which are labile.

Book Description
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.
