The successful reproduction of cultured brood stock is essential to the sustainable aquaculture of aquatic organisms. This book describes recent advances in the field of finfish reproductive biotechnology. The chapters in this volume are written by eminent scientists who review the progress and assess the status of biotechnology research that is applicable to the reproduction of finfish species for aquaculture. A wide range of topics is included starting with broodstock technologies such as broodstock genetics, broodstock nutrition, environmental control of maturation and impacts of stress on broodstock, gametes and progeny. The volume includes technologies for induction of ovulation and spermiation using synthetic hypothalamic peptides. Gamete technologies which are described include cryopreservation, chromosome set manipulation, disease prevention and control for gametes and embryos and the development of transgenic fish with enhanced production characteristics. Genetic and endocrine technologies for the production of monosex male and female fish stocks are also described.The closing chapter summarizes the discussion of each topic at the workshop, provides recommendations to industry and describes priorities of research and development. Researchers as well as teaching faculty in the aquaculture field will find this volume of great value.

The genetic improvement of fish for aquaculture and related fisheries has seen huge advances over recent years. Building upon the previous two editions of Aquaculture and Fisheries Biotechnology: Genetic Approaches, this 3rd edition offers a presentation of traditional selective breeding, modern genetic biotechnology, genomics, gene transfer and gene editing, and the latest developments in genetic biotechnology such as epigenetics, xenogenesis and genome-wide association study coupled with commercial application, the impact of government regulation and expectations for the future. It provides a firm grounding in relevant aspects of classical genetics, before focusing on particular aspects such as sex reversal and breeding as applied in aquaculture and fisheries. It also explores how more recent molecular genetics, genomics and biotechnology techniques can be used and combined in improvement programmes for fish and aquaculture species. A glossary explains the latest terminology used in biotechnology and genetics. This book will be useful for research scientists and students in marine biotechnology, aquaculture biotechnology, and fish genetics and breeding.

The fish processing industry is still far from the levels of scientific and technological development that characterize other food processing oper ations. It has also been slow in finding uses for by-products and processing wastes, compared with the meat and poultry industries. The utilization of fisheries by-products or wastes constitutes an area in which the application of modern techniques could potentially improve profitability. At present, increased attention is being focused on the application of new biotechnological methods to operations related to the seafood industry, with the objective of increasing its general efficiency. Because fish processing operations are commonly carried out in the vicinity of the sea, most of the resulting fish wastes have been disposed of by returning them to it. Pollution control measures and a better understanding of the valuable composition of the products extracted from the sea are expected to encourage their recovery and the develop ment of new products from them. In the past, fisheries wastes and species not used for food have been generally utilized through techno logical processes with a low level of sophistication, such as those for the production of animal feed and fertilizer. Limited economic success has accompanied the application of physi cal and chemical processes for the recovery of non-utilized fisheries biomass and for the production of quality products from them.

The seemingly inexhaustible oceans have proved to be finite after all. Capture of wild fish have leveled off since the mid-1980s, and many stocks of fish are fished so heavily that their future is threatened. And yet the world's appetite for fish has continued to increase, particularly as urban populations and incomes grow in developing countries. Aquaculture--fish farming--has arrived to meet this increased demand. Production of fish from aquaculture has exploded in the past 20 years and continues to expand around the world. But will aquaculture be sufficient to provide affordable fish to the world over the next 20 years? And what environmental and poverty problems will aquaculture face as it expands? Using a state-of-the-art computer model of global supply and demand for food and feed commodities, this book projects the likely changes in the fisheries sector over the next two decades. As prices for most food commodities fall, fish prices are expected to rise, reflecting demand for fish that outpaces the ability of the world to supply it. The model shows that developing countries will consume and produce a much greater share of the world's fish in the future, and trade in fisheries commodities will also increase. The authors show the causes and implications of these and other changes, and argue for specific actions and policies that can improve outcomes for the poor and for the environment.

Fish have been a major component of our diet and it has been suggested that fish/seafood consumption contributed to the development of the human brain, and this together with the acquisition of bipedalism, perhaps made us what we are. In the modern context global fish consumption is increasing. However, unlike our other staples, until a few years back the greater proportion of our fish supplies were of a hunted origin. This scenario is changing and a greater proportion of fish we consume now is of farmed origin. Aquaculture, the farming of waters, is thought to have originated in China, many millennia ago. Nevertheless, it transformed into a major food sector only since the second half of the last century, and continues to forge ahead, primarily in the developing world. China leads the global aquaculture production in volume, in the number of species that are farmed, and have contributed immensely to transforming the practices from an art to a science. This book attempts to capture some of the key elements and practices that have contributed to the success of Chinese aquaculture. The book entails contributions from over 100 leading experts in China, and provides insights into some aquaculture practices that are little known to the rest of the world. This book will be essential reading for aquaculturists, practitioners, researchers and students, and planners and developers.

The FISH Handbook for Biological Wastewater Treatment provides all the required information for the user to be able to identify and quantify important microorganisms in activated sludge and biofilms by using fluorescence in situ hybridization (FISH) and epifluorescence microscopy. It has for some years been clear that most microorganisms in biological wastewater systems cannot be reliably identified and quantified by conventional microscopy or by traditional culture-dependent methods such as plate counts. Therefore, molecular biological methods are vital and must be introduced instead of, or in addition to, conventional methods. At present, FISH is the most widely used and best tested of these methods. This handbook presents all relevant information from the literature and, based on the extensive experience of the authors, advice and recommendations are given for reliable FISH identification and quantification. The overall purpose of the book is to help scientists, consultants, students, and plant operators to get an overview of important microorganisms in biological wastewater treatment and to explain how FISH can be used for detecting and quantifying these microbes. A proper and reliable identification of dominant microorganisms is of great importance for research and new developments in the wastewater treatment industry, and it is important for optimization and troubleshooting of operational problems in present wastewater treatment plants. The book encompasses an overview of dominant microorganisms present in the wastewater treatment systems, which oligonucleotide probes (gene probes) to select for detection of these microbes by FISH, how to perform FISH (detailed protocols), how to quantify the microbes, and how to solve common problems of FISH. The book addresses several functional groups: nitrifiers, denitrifiers, polyphosphate-accumulating organisms, glycogen-accumulating organisms, bacteria involved in hydrolysis and fermentation, filamentous bacteria from bulking sludge, and scum-forming bacteria. A comprehensive collection of FISH-images showing dominant representatives of these groups helps readers to use FISH in the context of wastewater treatment.
