Crustacean And Mollusk Aquaculture In The United States

Crustaceans and mollusks are the glamor species of the seafood in dustry. Interest in aquaculture 1 of these invertebrates, frequently re ferred to as shellfishes, has resulted from increased exploitation of wild stocks. This has driven prices up to levels very attractive to investors. Much attention has been focused on crustaceans such as freshwater crawfishes, freshwater prawns, penaeid shrimps, and hom arid lobsters, and mollusks such as oysters, clams, mussels, scallops, and abalone. Success has been greatest with low trophic level species such as freshwater crawfishes and bivalve mollusks where nature subsidizes the aquaculturist in many ways, providing feed at low or no cost, seed for culture systems, waste removal, and so forth. Species such as homarid lobsters, penaeid shrimps, and abalone may have complicated life cycles, relatively slow growth rates, and other prob lems that have, so far, limited development of aquaculture of these high value, high visibility species. All taxa listed initially can be cultured from egg to egg in captivity, but many factors influence the commercial profitability of raising them in the United States. Investment in aquaculture of crustaceans and mollusks in the United States or by U. S. companies abroad has been extensive. Yet, only freshwater crawfishes and oysters have been cul tured on a truly large-scale, profitable basis to date in the United States proper. Other taxa such as penaeid shrimps and abalones are being cultured in the Orient where demand justifies expensive, labor intensive culture systems.

Shellfish Aquaculture and the Environment focuses primarily on the issues surrounding environmental sustainability of shellfish aquaculture. The chapters in this book provide readers with the most current data available on topics such as resource enhancement and habitat restoration. Shellfish Aquaculture and the Environment is also an invaluable resource for those looking to develop and implement environmental best management practices. Edited one of the world's leading shellfish researchers and with contributions from around the world, Shellfish Aquaculture and the Environment is the definitive source of information for this increasingly important topic.

Molluscan Shellfish Aquaculture is a useable manual for all those interested in an up-to-date introduction to the field. Each of the major cultured species of commercial importance is covered, providing cutting-edge information of practical use to all those involved in shellfish aquaculture. The book’s editor and chapter authors are among the most widely known and respected authorities working in the industry and academia. Species covered include mussels, clams, oysters (including pearl oysters), scallops, cephalopods, abalone and gastropods. Molluscan Shellfish Aquaculture contains a huge wealth of information of great use for personnel working in the industry, with chapters covering site selection, hatchery construction, disease, biofouling, best management practice and certification. 5m Books

Coastal farming and ocean ranching of marine fish, shellfish, crustaceans, and seaweed are a major and growing industry worldwide. In the United States, freshwater aquaculture is rapidly becoming a significant commercial activity; however, marine aquaculture has lagged behind. This book examines the obstacles to developing marine aquaculture in the United States and offers specific recommendations for technology and policy strategies to encourage this industry. The volume provides a wealth of information on the status of marine aquacultureâ€"including comparisons between U.S. and foreign approaches to policy and technology and of the diverse species under culture. Marine Aquaculture also describes problems of coordination of regulatory policy among various federal, state, and local government agencies and escalating competition for the use of coastal waters. It addresses environmental concerns and suggests engineering and research strategies for alleviating negative impacts from marine aquaculture operations.

When Drakes Estero, which lies within the Point Reyes National Seashore (PRNS) about 25 miles northwest of San Francisco, California, was designated by Congress in 1976 as Potential Wilderness, it contained a commercial shellfish mariculture operation. Oyster mariculture began in Drakes Estero with the introduction of the nonnative Pacific oyster in 1932, and has been conducted continuously from that date forward. Hence, the cultural history of oyster farming predates the designation of Point Reyes as a National Seashore in 1962. Nevertheless, with the approach of the 2012 expiration date of the current National Park Service (NPS) Reservation of Use and Occupancy (RUO) and Special Use Permit (SUP) that allows Drakes Bay Oyster Company (DBOC) to operate within the estero, NPS has expressed concern over the scope and intensity of impacts of the shellfish culture operations on the estero's ecosystem. Public debate over whether scientific information justifies closing the oyster farm led to the request for this study to help clarify the scientific issues raised with regard to the shellfish mariculture activities in Drakes Estero.

Hardbound. Clams have been harvested along the coasts of North America for as long as records have been kept. They support commercial, sport and subsistence fisheries although unfortunately, with few exceptions, the harvest of these invertebrates is declining. This decline is probably caused by a number of factors including pollution and overfishing. In an effort to ameliorate this situation, interest in the aquaculture of these species has grown.Intensive semi-controlled clam culture has been attempted in North America for almost three decades. However, it was not until the last decade that a number of entrepreneurs actually began clam farming and developing successful and profitable operations. This success has been possible because of numerous scientific and practical contributions made by a great number of scientists, growers, and clammers over the years, and by a healthy market demand caused by a downward trend in the wild harvest.Many of the

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.
