Download or read book Aquaculture in China written by Jian-Fang Gui and published by John Wiley & Sons. This book was released on 2018-03-28 with total page 1074 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

More than one hundred scholars have provided new keys, illustrations, and annotated species lists for over 3,500 species of intertidal and many shallow water marine organisms ranging from protozoans to sea squirts. This expanded volume covers sponges, sea anemones, hydroids, jellyfish, flatworms, polychaetes, amphipods, crabs, insects, snails, clams, chitons, and scores of other important groups. The Fourth Edition also features introductory chapters on marine habitats and biogeography, interstitial marine life, and intertidal parasites, as well as expanded treatments of common planktonic organisms likely to be encountered in near-to-shore shallow waters.
Download or read book The Ocean Volume 2 written by Herve Claustre and published by Frontiers Media SA. This book was released on 2023-07-25 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean was the origin of life on earth billions of years ago and it is vital for the future of humanity. It is vast, deep, harsh and somehow “rebellious” to uncover its secrets and hence, there is much that is unexplored and misunderstood. Scientists need to study the ocean to better understand its functioning and properties, as well as how they shape our environment and impact us. For example, do you know what the role of the ocean is on weather and climate? There still remains so much to explore in ocean biodiversity and the diverse resources that can be found (for example, fish stocks, bio-molecules, and also minerals, oil, and gas). How can we make sure that our use of these resources is done sustainably and how can we minimize our impacts (e.g. pollution, acidification) on the ocean as our human population increases? In this Collection of Frontiers for Young Minds, scientists from various disciplines in oceanography share their knowledge and motivations, give insights in innovative tools and recent discoveries to better understand this ocean. The Collection will target a large range of oceanic environments from the open ocean to the coast, the surface to the abysses also including specific areas like coral reefs or sea-ice environments. It will cover marine disciplines that range from physics to chemistry, from biology to ecology and from economy to conservation and policies. It will address innovative tools and methods that are used to observe and characterize oceanic properties and features: ships and satellites, the highly diverse variety of robots as well as genomics or artificial intelligence. Finally, it will encompass a great variety of scales, ranging from the diel to geological time-scales and from loco-regional to global scales and also from the tiniest cells to the biggest living animals on our planet. The United Nations have declared the 2021-2030 period as the “Decade of Ocean Science for Sustainable Development”, stressing the urgent need to approach fundamental issues related to the ocean and the future of humanity on well sounded scientific grounds and knowledge. This Ocean Collection aims to provide information to young readers that will help them to increase their understanding of the ocean and its central role in nature and our lives. We hope to empower them to make informed decisions in these challenging times and to engage to protect, study and enjoy its richness. See here our previous Volume 1!

Download or read book Mud Crab Aquaculture written by Colin Charles Shelley and published by Fao Inter-Departmental Working Group. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are four species of mud crab, Scylla serrata, S. tranquebarica, S. paramamosain and S. olivacea that are the focus of both commercial fisheries and aquaculture production throughout their distribution. They are among the most valuable crab species in the world, with the bulk of their commercial production sent live to market. This is the first FAO aquaculture manual on this genus, covering everything from its basic biology and aquaculture production, through to stock packaging and being ready to go to market. Information on mud crab biology, hatchery and nursery technology, grow-out systems, disease control, processing and packaging has been collated in this manual to provide a holistic approach to mud crab aquaculture production. Compared with other types of aquaculture, mud crab culture still has a large number of variants, including: the use of seedstock collected from the wild, as well as produced from a hatchery; farming systems that range from very extensive to intensive, monoculture to polyculture; and farm sites that vary from mangrove forests to well-constructed aquaculture ponds or fattening cages. As such, there is no one way to farm mud crabs, but techniques, technologies and principles have been developed that can be adapted to meet the specific needs of farmers and governments wishing to develop mud crab aquaculture businesses. Each of the four species of Scylla has subtly different biology, which equates to variations in optimal aquaculture production techniques. Where known and documented, variants have been identified, where not, farmers, researchers and extension officers alike may have to adapt results from other species to their mud crab species of choice and local climatic variables. Compared with many other species that are the subject of industrial scale aquaculture, mud crabs can still be considered to be at an early stage of development, as the use of formulated feeds for them is still in its infancy and little work has yet been undertaken to improve stock performance through breeding programmes.
