Mucosal Health in Aquaculture is an essential reference on mucosal health for the diverse aquaculture community. Rich in explanatory figures and schematics, the book includes important concepts such as structural and cellular composition of mucosal surfaces in fish and shellfish, known functional roles of molecular and cellular actors during pathogen invasion, impacts of nutrition on the mucosal barriers, impacts of chemical treatments on mucosal surfaces, mucosal vaccines and vaccination strategies, and more. The health of cultured aquaculture species is critical in establishing the sustainable growth of the aquaculture industry worldwide, and mucosal health is of particular interest to those working in aquaculture because mucosal surfaces (skin, gill, intestine, reproductive tissues) constitute the first line of defense against pathogen invasion. Mucosal Health in Aquaculture captures the latest research on mucosal barriers in aquaculture species and their impacts on nutrition and immunity to ensure sustainable aquaculture development.

This book is about important relevant recent research topics in sustainable aquaculture practices. A critical assessment of the sustainable fishing methods and the aspect of sustainable aquaculture feed is presented in this volume. A special focus has been given to socio-economic and environmental assessment of aquaculture practices and analysis of carbon footprint under an intensive aquaculture regime. Aquaponics as a niche for sustainable modern aquaculture has been highlighted. The effect of use of pharmaceuticals to prevent fish disease on the surrounding marine environment is an emerging area of concern, and a critical discussion on this aspect is included in the book. The spread of organic waste and nutrients released by fish farms to natural water bodies has raised considerable concerns. Therefore the methods to prevent their dispersion and removal (treatment) have been comprehensively covered in this book. This book is an essential read for academician, researchers, and policy makers in the field of aquaculture.

Fishery products are the world's most important source of animal protein, especially for the poor. Meeting the basic human needs for protein foods in the future will be a difficult challenge, especially as demand for fish has doubled since the 1950s. Realistically we can not expect to catch more food from the sea, so we must now turn to farming the waters, not just hunting them. The new challenge for planners is to accelerate aquaculture development and to plan for new production. As millions of people are moving from rural, inland areas to coastal cities we need to make urban areas not only centers of marketing and distribution, but also of production, particularly using recycled urban wastewater. This book on urban aquaculture includes papers from authors in the USA, Europe and Asia that review these emerging issues from the perspective of both developed and developing countries.

This book is dedicated to the Silver Bream, a fish too long neglected by anglers, wildlife enthusiasts and science. In fact, this is the first book ever devoted to this freshwater fish.

This book compiles the latest findings in the field of marine and brackishwater aquaculture. It covers significant topics such as techniques of culture of live feeds (microalgae, rotifer, Artemia, marine copepod & polychaetes), while also highlighting vital themes like the culture and applications of free and marine sponge associated microbial probiotics, controlled breeding, seed production and culture of commercially important fin and shell fishes. Moreover, the book focuses on the breeding and culture of marine ornamental fishes, sea cucumber and sea urchin and discusses seaweeds culture, aqua feed formulation and nutrition, water quality management in hatchery and grow-out culture systems, fish disease diagnosis and health management and cryopreservation of fish gametes for sustainable aquaculture practices, all from a multidimensional perspective. The global fish production was 154 million tonnes in 2011 which more or less consisted of capture and culture fisheries (FAO, 2012). Roughly 80% of this is from inland-freshwater aquaculture and the remainder from capture fisheries in the marine and brackishwater sector. However, marine and brackishwater catches have recently begun to diminish due to overexploitation, climate change and pollution. The UNEP report affirmed that if the world remains on its current course of overfishing, by 2050, the ocean fish stock could become extinct or no longer commercially viable to exploit. In these circumstances, aquaculture is considered to be a promising sector to fulfill our future protein requirement. However, brackishwater and marine fish production now face serious challenges due to e.g. lack of quality fish seeds, feeds, poor water quality management and diseases. Fisheries and aquaculture sectors play a vital role as potential sources of nutritional security and food safety around the globe. Fish food is rich in protein, vitamins, phosphorous, calcium, zinc, selenium etc. In addition, fish contains omega-3 fatty acids, which help to prevent cardiovascular diseases. Fish food can also provide several health benefits to consumers. The omega 3 fatty acids found in fish can reduce the levels of LDL cholesterol (the "bad" cholesterol) and increase the HDL levels (the "good" cholesterol). Research conducted in Australia has proved that fish consumption can be used to cure hypertension and obesity. It is also reported that people who ate more fish were less prone to asthma and were able to breathe more easily. Omega 3 fish oil or fish consumption can help to prevent three of the most common forms of cancer: breast cancer, colon and prostate cancer. The omega 3 fatty acids present in fish or fish oil induce faster hair growth and prevent hair loss. Since most varieties of fish are rich in protein, eating fish helps to keep hair healthy. Furthermore, fish or fish oil helps in improving the condition of dry skin, giving it a healthy glow. It is useful in treating various skin problems such as eczema, psoriasis, itching, redness of skin, skin lesions and rashes. It is well known that eating fish improves vision and prevents Alzheimer's and type-2 diabetes, and can combat arthritis. Further, fish oil or fish is good for pregnant women, as the DHA present in it helps in the development of the baby's eyes and brain. It helps to avoid premature births, low birth weights and miscarriages. In addition, it is widely known that fish can be a good substitute for pulses in cereal-based diets for the poor. The global fish production was roughly 154 million tonnes in 2011 (FAO, 2012). It is estimated that by 2020 global fish requirements will be over 200 million tonnes; as such, innovative technological improvements are called for in order to improve the production and productivity in fisheries. In this context, this book provides valuable information for academics, scientists, researchers, government officials and farmers on innovative technological advances for sustainable fish production using aquaculture methods. The book identifies the main issues and trends in marine and brackishwater aquaculture from a global perspective in general and in the Indian context in particular. It includes 23 chapters written by prominent researchers from various institutes and universities across India, who address the latest aquaculture technologies with distinctive approaches to support academics, researchers and graduates in the fields of Fisheries, Aquaculture, Marine Science, Marine Biology, Marine Biotechnology, Zoology and Agricultural Sciences. Our thanks go to our contributors; we are confident that all readers will immensely benefit from their valued expertise in the field of marine and brackishwater aquaculture.

This volume provides an abundance of valuable first-hand information about the diversity, biology, ecology culture of the portunid crabs of the word seas. Marine crabs play an important role directly or indirectly in the livelihood of millions of people around the world. They have been reported to make up about 20% of all marine crustaceans caught, farmed, and consumed worldwide. Among these marine crabs, portunid crabs (or swimming crabs of the family Portunidae) assume greater significance in the marine industry, owing to their delicate meat with nutritional qualities. Although several species of portunid crabs are edible and commercially important, only a few species have been widely cultivated. This is largely due to the lack of information on the biology of portunid crabs. Keeping this in view, this volume presents the biology and aquaculture of marine portunid crabs. This volume will be of great use for researchers and students of disciplines such as fisheries science, marine biology, aquatic biology and fisheries, and zoology, and will also serve as a standard reference for college, university, and research libraries around the world.
