This authoritative review will be valuable reference for marine biologists, ecologists, and taxonomists. It is also an essential handbook for the penaeid fisheries biologist or aquaculturist and is a prerequisite for the rational exploitation and cultivation of penaeids.**Although penaeids are a large and diverse decapod group which have been exploited commercially in both fisheries and aquaculture for hundreds of years, no comprehensive review of their biology has never been written. The group's commercial importance has led to an unbalanced literature, dominated by the fisheries and aquaculture aspects of the genus Penaeus, often without an appreciation of their underlying biology.**This review adopts a multidisciplinary approach to give a comprehensive and up-to-date account of morphology, taxonomy (including larvae), zoogeography, physiology, reproduction, feeding, growth, behaviour, and life histories. Chapters discussing the parasites of, and predation on penaeids, are also included. So much new material is presented that the book is more than just a review of the existing literature. In synthesising the published information across this diverse family, it puts the commercially important species and genera into a larger perspective, pointing to deficiencies in our understanding and creating a framework for areas of future research.

Crustaceans adapt to a wide variety of habitats and ways of life. They have a complex physiological structure particularly with regard to the processes of growth (molting), metabolic regulation, and reproduction. Crustaceans are ideal as model organisms for the study of endocrine disruption and stress physiology in aquatic invertebrates. This book

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

During the last decades, aquatic resources have been severely depleted due to human-induced factors such as overexploitation and pollution and more recently due to deviations in the physicochemical parameters of oceans, dramatic changes in weather patterns and melting of glaciers. The effects of these man-made factors are occurring in a relatively shorter time scale and, in many cases, are beyond the capacity of organisms to adapt to these deviations. The majority of natural aquatic resources, which are one of the most important food sources on the planet, are being used to the extent that limits their capacity for regeneration. Despite ongoing attempts towards developing strategies for long-term management of aquatic resources all over the world, efforts have met with limited success. Thus, the sustainable use of aquatic resources has become a very important reality considering a projected human population of 11 billion by the year 2100. With this reality in mind, the purpose of this book is to shed more light on the field of marine ecology by emphasizing the diversity of aquatic life on earth and its importance both as part of a balanced ecosystem and as part of critical source of food on earth. The book covers important findings, discussions and reviews on a variety of subjects on environmental and competitive interactions of marine organisms at different trophic levels and their effects on the productivity, dynamics and structure of marine ecosystems around the world. Each chapter focuses on a specific case in the field of marine ecology and was written by researchers with years of experience in their respective fields. We hope that academicians, researchers and students as well as experts and professionals working in the field of marine ecology will benefit from these contributions. We also hope that this book will inspire more studies to help better understand the marine environment and develop strategies to better protect this crucial element of life on earth.

The Biology of Crustacea, Volume 10: Economic Aspects: Fisheries and Culture focuses on economic aspects of elements of crustacean biology associated primarily with the production of human food, namely, fisheries and culture. Organized into five chapters, this book deals first with the groups comprising the commercially important shrimps and prawns and their near relatives, as well as the generally used fishing method. It then describes the role and impact of body form in the biology and especially the fisheries of crabs. Subsequent chapter centers on lobsters and their kin, particularly the impact on fisheries methods and management approaches of behavioral responses to environment, modes of reproduction, recruitment, and population dynamics. Culture methods and factors important in managing systems through water quality control are then reported. Lastly, large-scale culture of major decapod groups, including the general biological characteristics of decapods relevant to aquaculture, is presented. This book will help stimulate the further exploration of some of the most fascinating and exciting problems in applied crustacean biology.

St Lucia is the world's oldest protected estuary and Africa's largest estuarine system. It is also the centerpiece of South Africa's first UNESCO World Heritage Site, the iSimangaliso Wetland Park, and has been a Ramsar Wetland of International Importance since 1986. Knowledge of its biodiversity, geological origins, hydrology, hydrodynamics and the long history of management is unique in the world. However, the impact of global change has culminated in unprecedented challenges for the conservation and management of the St Lucia system, leading to the recent initiation of a project in support of its rehabilitation and long-term sustainability. This timely volume provides a unique source of information on the functioning and management of the estuary for researchers, students and environmental managers. The insights and experiences described build on over 60 years of study and management at the site and will serve as a valuable model for similar estuaries around the world.
