Nutrition, Physiology, and Metabolism of Crustaceans by Elena Mente Pdf
This study examines protein metabolism and growth in decapod crustaceans. Recognizing that successful commercial aquaculture of crustacean species is dependent on nutrition, the book focuses on the knowledge of crustacean nutritional requirements and factors affecting growth.
The Physiology of Crustacea, Volume I: Metabolism and Growth deals with the physiological aspects of metabolism and growth in hundreds of species and higher taxa of Crustacea. The book explores processes related to the morphology and development of crustaceans, from blood chemistry to feeding and nutrition, digestion, excretion, molting, autotomy, and regeneration. This volume is organized into 17 chapters and begins with an overview of crustacean biology and systematics as well as ontogeny and phylogeny. The book then discusses the metabolic requirements of crustacean respiration, the mechanisms of gas exchange, and respiratory transport. The next chapters focus on the biochemistry of animal pigments such as hemoglobin and melanin and the crustacean blood chemistry, blood flow, heart function, feeding mechanisms, and vitamin contents. The book also discusses the digestive system of crustaceans, along with osmotic and ionic regulation; the excretory system; the link between ecology and metabolism; and sex differentiation in Crustacea. This book is written primarily for biologists, physiologists, and zoologists, as well as advanced students and research workers who are interested in problems of comparative physiology.
In the Wrong Place - Alien Marine Crustaceans: Distribution, Biology and Impacts by Bella S. Galil,Paul F. Clark,James T. Carlton Pdf
In The Wrong Place: Alien Marine Crustaceans - Distribution, Biology And Impacts provides a unique view into the remarkable story of how shrimps, crabs, and lobsters – and their many relatives – have been distributed around the world by human activity, and the profound implications of this global reorganization of biodiversity for marine conservation biology. Many crustaceans form the base of marine food chains, and are often prominent predators and competitors acting as ecological engineers in marine ecosystems. Commencing in the 1800s global commerce began to move hundreds – perhaps thousands – of species of marine crustaceans across oceans and between continents, both intentionally and unintentionally. This book tells the story of these invasions from Arctic waters to tropical shores, highlighting not only the importance and impact of all prominent crustacean invasions in the world's oceans, but also the commercial exploitation of invasive crabs and shrimps. Topics explored for the first time in one volume include the historical roots of man's impact on crustacean biogeography, the global dispersal of crabs, barnacle invasions, insights into the potential scale of tropical invasions, the history of the world's most widely cultured shrimp, the invasive history and management of red king crabs in Norway, Chinese mitten crabs in England, and American blue crabs in Europe, the evolutionary ecology of green crabs, and many other subjects as well, touching upon all ocean shores.
Nutrition and Feeding of Fish and Crustaceans by Jean Guillaume Pdf
Drawing on laboratory and farm studies, the book reviews in detail the current state-of-the-art scientific research knowledge of fish and crustacean nutrition, from larvae to juvenile fish, through to the final stages of harvesting. Topics covered include issues surrounding the formulation, manufacture and delivery of feedstuffs to fish farms and the text provides a dual focus on fish and shrimp feeding requirements addressing practical applications as appropriate for the European aqualculture industry.
Ecophysiology of the European Green Crab (Carcinus maenas) and Related Species by Dirk Weihrauch,Iain Mcgaw Pdf
Ecophysiology of the Green Shore Crab (Carcinus maenas) and Related Species: Mechanisms Behind the Success of a Global Invader provides an in-depth perspective of this devastatingly invasive coastal species. During the last 175 years, Carcinus maenas has spread around the globe by human activities. Because of its ability to flourish in a wide variety of ecosystems and outcompete native species it has been listed as one of the top 100 worst global invaders. Written by international experts, this book focuses on Carcinus maenas and discusses other brachyurans with similar physiologies as comparisons, including control systems and mechanisms used. This book serves as a valuable resource for researchers in marine biology and invasive biology, as well as for university lecturers, government or environmental agencies. Gathers all information on ecological physiology of this important species into one place Discusses how this one species of crab has managed to be spread around the globe and survive in many different environments Features a chapter by First Nations members on how this species may impact indigenous fisheries and culture
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.
Physiology by Les Watling,Martin Thiel,Ernest S. Chang Pdf
The Crustacea is one of the dominant invertebrate groups, displaying staggering diversity in form and function, and spanning the full spectrum of Earth's environments. Crustaceans are increasingly used as model organisms in all fields of biology, as few other taxa exhibit such a variety of body shapes and adaptations to particular habitats and environmental conditions. Physiology is the fourth volume in The Natural History of the Crustacea series, and the first book in over twenty-five years to provide an overview of the comparative physiology of crustaceans. An understanding of physiology is crucial to a comprehension of the biology of this fascinating invertebrate group. Written by a group of internationally recognized experts studying a wide range of crustacean taxa and topics, this volume synthesizes current research in a format that is accessible to a wide scientific audience.
