Although there are excellent books on specific aspects of the seafood industry, few, if any, offer both the breadth and depth of information that the editors and authors of The Seafood Industry provide here. The Seafood Industry is designed to cover the spectrum of seafood topics, taking the products from the water to the dinner plate and every stop in between. Information and insights into commercially important species of finfish and shell and their handling and processing are furnished. Chapters are included on fish such wide-ranging topics as retail merchandising of seafood, plant cleaning and sanitation, transportation, and product packaging. Emerging issues and interests, such as aquaculture, waste treatment, and government regulations, also are covered. The information is written so that the processor, wholesale buyer, retailer, or consumer can understand it and put it to practical application. Yet the student and the scientist can find much valuable information within the various chapters. The material included here has proven its practicality, as it is adapted from a self-study course that has been used by hundreds of people in roughly forty states and fifteen foreign countries. The editors and authors have made every effort to furnish the most up-to-date information and technologies available. However, as with any dynamic industry, change is constant. Fishery stocks ebb and flow; consumption patterns shift; new technologies are devised and implemented; and government rules and regulations are rewritten and enacted.

This two-volume work presents a summary and review of the current state of lobster biology, ecology, physiology, behavior, and management. It emphasizes the biology of clawed lobsters (Nephropidae) and spiny lobsters (Palinuridae), with attention also given to slipper lobsters (Scyllaridae) and coral lobsters (Synaxidae). The first chapter of Volume 1 provides an overview of the general aspects of lobster biology that serves as an introduction for readers of both volumes. Subsequent chapters examine the topics of growth, neurobiology, reproduction, nutrition, pathology, social behavior, and migration patterns. The chapters in Volume II consider the ecology, population dynamics, fishery biology, and aquaculture of spiny and clawed lobsters. The topics selected in both volumes represent areas of current research whose findings have not been previously synthesized into a coherent form. An important feature of these volumes is the emphasis on the interaction between biology and management and culture. Many of the contributors have done research in both applied and basic biology and can articulate both points of view. The interaction between basic and applied research is of fundamental importance in these volumes in which management aspects of the research have been integrated with the basic biology of lobsters. The Biology and Management of Lobsterswill be of interest to crustacean biologists, marine biologists and ecologists, zoologists, physiologists, animal behavior researchers, aquaculturalists, fisheries biologists and managers of fisheries, neurobiologists, pathologists, and food scientists.

The global trade of aquatic organisms for home and public aquariums, along with associated equipment and accessories, has become a multi-billion dollar industry. Aquaculture of marine ornamental species, still in its infancy, is recognized as a viable alternative to wild collection as it can supplement or replace the supply of wild caught specimens and potentially help recover natural populations through restocking. This book collects into a single work the most up-to-date information currently available on the aquaculture of marine ornamental species. It includes the contributions of more than 50 leading scientists and experts on different topics relevant for the aquaculture of the most emblematic groups of organisms traded for reef aquariums. From clownfish, to angelfish, tangs and seahorses, as well as corals, anemones, shrimps, giant clams and several other reef organisms, all issues related with the husbandry, breeding, and trade are addressed, with explanatory schemes and illustrations being used to help in understanding the most complex topics addressed. Marine Ornamental Species Aquaculture is a key reference for scientists and academics in research institutes and universities, public and private aquaria, as well as for hobbyists. Entrepreneurs will also find this book an important resource, as the culture of marine ornamental species is analyzed from a business oriented perspective, highlighting the risks and opportunities of commercial scale aquaculture of marine ornamentals.

The only hope of supplying the world's ever-increasing demand for aquatic food products is through aquaculture, and the vast majority of this is conducted in ponds. Although pond aquaculture may appear at first to be an archaic method of growing aquatic animals, it is one that is consistently profitable when the pond is managed properly. The most important aspect of pond management is the maintenance of adequate environmental conditions for good growth and health of the animal under culture. Water quality in ponds also extends into the areas of environmental protection and food quality and safety, which are increasingly important in today's world. This book provides the most complete, up-to-date account of water quality and its management in aquaculture ponds. It provides background information on the physical, chemical, and biological environment of pond aquaculture, and illustrates how the proper balance of these factors is the essential ingredient for successful production of fish and other aquatic animals. Management techniques for the control of water quality and productivity include liming, fertilization, mechanical aeration, water exchange, and the use of algicides and herbicides. The authors examine the effects of pollution on aquaculture and the validity of current criticisms by environmentalists. This book will be of great benefit to students, extension agents, policy-makers, government officials and the commercial aquaculture industry.

Coastal lagoons and estuaries, lying at the boundary between ocean and land, house a unique mosaic of habitats, giving rise to high species diversity and the creation of ecotones. They are also ecologically and economically important ecosystems that provide many ecosystem services. Yet, these coastal ecosystems are facing a gamut of human-induced threats. This booklet is the fourth in the Coastal Ecosystems Series, published in an attempt to address the lack of information available to the general public regarding the threats to coastal ecosystems.
