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.

This is a reprint of the first revision of this classic. Originally published in 1953 as Fishery Bulletin #74 for the US Department of the Interior, Fish and Wildlife Service. The "Gulf of Maine" is defined as an area from the Nantucket Shoals and Cape Cod in the west to Cape Sable in the east. The aim of the book was to provide a handbook for the easy identification of the fishes that occur in the Gulf of Maine, with summaries of what is known about the distribution and relative abundance together with information on the life history of each species. The authors used the 150-fathom boundary as the arbitrary offshore boundary as this will exclude almost all "deep-sea" fishes, which are numerous in the basin of the open Atlantic. Combining information gleaned from the literature as well as surveys from a large number of cruises, the volume covers the Cyclostomes, cartilaginous fishes, torpedoes, skates and rays and the bony fishes. The descriptions are as non-technical as is compatible with scientific accuracy and are limited to external features that will aid in identification in the field.

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.

"Oryzias latipes," known as medaka, is a model organism from East Asia. Breeding of this small, egg-laying freshwater teleost fish has long been popular among hobbyists in Japan. Now, as biological science has entered the genome era, the medaka provides significant advantages that make it one of the most valuable vertebrate models: a large collection of spontaneous mutants collected over a century, the presence of highly polymorphic inbred lines established over decades, and a recently completed genome sequence. This book is the first comprehensive monograph to cover a variety of medaka research. It opens with a historical view of medaka, followed by a series of research topics in the four major areas where the medaka is increasingly important: genomics, genetics, and resources; organogenesis and disease models; germ cells, sex determination, and reproduction; and evolution. Readers will find state-of-the-art information on medaka genetics and genomics such as the first isolation of active transposons in vertebrates, the influence of chromatin structure on sequence variation, fine QTL analysis, and versatile mutants as human disease models.

This book is an essential reference tool for all those who have a passion for trees as well as those who work in tree-related professions whether they be garden managers, forest and country park wardens, foresters, woodland managers or those working in the fields of arboriculture and horticulture. Moreover, this volume is also intended to be a textbook of trees aimed at arboriculture, horticulture and forestry students studying at National Diploma and Higher National Diploma levels and for candidates of the Royal Horticultural Society's Diploma in Horticulture and the Society's Master of Horticulture [RHS] Award. Other books in this field have tended to concentrate either on the science of trees, or have specialized on their management, culture or aesthetics. This volume, however, is a comprehensive study that illustrates the relationship between all these subjects.

This cutting-edge resource includes up-to-date information on zebrafish physiology and the tools used to study it, not only as a model species for studies of other vertebrates but with application for studies of human disease and aquatic toxicology. The utility of zebrafish for physiological research is based on several key features including i) a "fully" sequenced genome, ii) rapid ( 3 month) generation times), iii) their capacity to produce large numbers of externally fertilized eggs, iv) optical transparency of embryos and larvae, and v) the applicability of reverse and forward genetics to assess gene function. Gene knockdown in embryos and the production of transgenic strains are now standard techniques being used to assess physiology. This book will be of keen interest not only to the typical readers of Fish Physiology but also to biomedical researchers, toxicologists and developmental biologists.

Key Features
* Integrates and synthesizes the biology of the zebrafish under one cover
* Features contributions from the leading researchers in their fields
* Reaches a wider audience of researchers and biologists with its broad inclusion of subjects relating to zebrafish physiology

Fish farming has increased in status equal to cattle farming as a source of food for mankind. In developing countries fish and shellfish provide inexpensive animal protein, while in developed countries aquaculture is expected to produce more fish and shellfish as a source of low-calorie protein for health conscious individuals. In such an era, knowledge of fish farming technologies of different countries, strongly influenced by cultural factors, is of valuable importance. The primary production techniques of fish farming in Japan described here have an emphasis on practical technology. This second edition reflects the changes in both quantity of production and technology in Japanese aquaculture. The statistics have been revised and the text rewritten to suit the current status of aquaculture in Japan; new aquaculture species have been included and discussions on marine ranching and biotechnology for aquaculture added.

This second volume in the series covers such topics as DNA fingerprinting of fishes, the cytochromes P450 in fish, the molecular biology of bacterial fish diseases, and new insights into the origins of the diversity and distribution of fish antifreeze proteins. The book will be of great value to fisheries scientists, animal biochemists, physiologists and endocrinologists, and aquaculturists. It will provide researchers and students alike with a pertinent information source from theoretical and experimental angles.

On May 18, 1605, George Waymouth, captain of the English ship Archangel, anchored in the lee of Monhegan Island, finding shelter from a three-day storm. Putting ashore, the crew found fresh water to drink, wood to burn, and lobsters aplenty in the shoreline rocks. Today, lobstering and lobstermen are American icons of rugged individualism, and their way of life has enlivened and colored the countless bays and coves of New England. The Lobstering Life puts readers in the boats, on the docks, in the bars, and in the lives of the men and women who pull "bugs" from the sea to sustain a cussedly independent, much admired way of life. Not since Peter Matthiessen's bestselling Men's Lives has this trade been so vibrantly brought to life.

In its third edition, this praised book demonstrates how the living systems modeling of aquatic ecosystems for ecological, biological and physiological research, and ecosystem restoration can produce answers to very complex ecological questions. This book further offers an understanding developed in 25 years of living ecosystem modeling and discusses how this knowledge has produced methods of efficiently solving many environmental problems. Public education through this methodology is the additional key to the broader ecosystem understanding necessary to allow human society to pass through the next evolutionary bottleneck of our species. Living systems modeling as a wide spectrum educational tool can provide a primary vehicle for that essential step.
This third editon covers the many technological and biological developments in the eight plus years since the second edition, providing updated technological advice and describing many new example aquarium environments.
