Book Description
This book explains how the beautiful goldfish body develops from a single fertilized egg and how this developmental process was changed during the process of domestication. The contents can be categorized as follows: i) numerous high-quality live photo images of embryonic and larval stage goldfish, ii) detailed descriptions of skeletogenesis with fluorescent microscopic and histological images, iii) the most advanced interpretation of the relationship between artificial selection and developmental processes, iv) future perspectives of the application of the genome editing techniques for the ornamental goldfish breeding, and v) methodological descriptions for goldfish developmental biology. Goldfish is a popular ornamental domesticated fish species, and its highly diverged morphological features and color variations attract fanciers. The goldfish has been spread all over the world by breeders, and this fish has also been employed as an experimental organism by researchers in the field of life science. However, so far, no available scientific books provide a detailed description of the embryogenesis and morphogenesis of this animal. Compared with the number of published fancier books, the number of books on goldfish biology is very few. This publication will be useful not only for the research community particularly in the fields of developmental biology, evolutionary biology, zoology, aquaculture, fishery science, and related areas but also for enthusiastic goldfish fanciers and breeders.

Book Description
Fish resources in natural water bodies are tending to decrease due to intensified fishing, the extensive construction of hydropower plants on rivers, and the pollution of seas and freshwater basins by indus trial and agricultural wastes. Nowadays only artificial fish rearing can meet man's requirements in fish products. Fish breeding is still very young as compared to plant breeding and animal husbandry. Although fishes have been reared artificially since ancient times in certain Asian countries, this usually included the cultivation of embryos and larvae caught in rivers and lakes. Among the exceptions, only the common carp Cyprinus carpio and the domesticated variety of the crucian carp, the goldfish Carassius auratus, which were cultivated in the East, may be mentioned. Com mon carp breeding began in China about 2000 years ago but was la ter banned by one of the emperors and started again only relatively recently. The goldfish has been cultivated for decorative purposes for about 1000 years. Many remarkable varieties of the goldfish have been developed in China and later in Japan. The first improved breeds (German "races") of the common carp known in Europe appeared after the domestication of the Da nube wild carp in the seventeenth and eighteenth centuries. Local breeds of the carp were probably established somewhat later in Chi na, Japan and Indonesia; even now these breeds have only minor differences as compared to their ancestor, the Asian wild carp.

Book Description
The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.

Book Description
Polyploidy – whole-genome duplication (WGD) – is a fundamental driver of biodiversity with significant consequences for genome structure, organization, and evolution. Once considered a speciation process common only in plants, polyploidy is now recognized to have played a major role in the structure, gene content, and evolution of most eukaryotic genomes. In fact, the diversity of eukaryotes seems closely tied to multiple WGDs. Polyploidy generates new genomic interactions – initially resulting in “genomic and transcriptomic shock” – that must be resolved in a new polyploid lineage. This process essentially acts as a “reset” button, resulting in genomic changes that may ultimately promote adaptive speciation. This book brings together for the first time the conceptual and theoretical underpinnings of polyploid genome evolution with syntheses of the patterns and processes of genome evolution in diverse polyploid groups. Because polyploidy is most common and best studied in plants, the book emphasizes plant models, but recent studies of vertebrates and fungi are providing fresh perspectives on factors that allow polyploid speciation and shape polyploid genomes. The emerging paradigm is that polyploidy – through alterations in genome structure and gene regulation – generates genetic and phenotypic novelty that manifests itself at the chromosomal, physiological, and organismal levels, with long-term ecological and evolutionary consequences.

Book Description
Goldfish come in a range of sizes and looks that is truly amazing. Fancy Goldfish is the most encompassing and thorough treatment of the fancy goldfish hobby to date. With photographs, essays, and instructions from a variety of experts, this book will provide readers with all they need to embark on the fascinating hobby of raising fancy goldfish. Fish veterinarian Dr. Johnson writes extensively on goldfish health and disease, including microscopy techniques, diagnosis, treatment, and prevention of the full span of goldfish diseases. In a helpful and accessible "frequently asked questions" format, Richard Hess provides a general introduction to all aspects of the hobby, from selecting the best fish, aquarium setup, maintenance, feeding, sexing and breeding, and keeping fish healthy. Jackie and Louis Chan, major exporters of fancy goldfish from China, discuss the tradition of goldfish appreciation in China, and a chapter on Japanese goldfish describes the history and standards of uniquely Japanese varieties and the techniques and secrets of Japanese breeders. Izhak Kroshinsky, a leading breeder of Ranchu in America, describes his methods for cultivating a superior strain over the last twenty-five years. With over 100 color photographs of beautiful specimens and rare varieties by Fred Rosenzweig, this book is a stunning visual reference as well.

Winner of 2014 AAAS/Subaru SB&F Prize for Best Young Adult Science Book Longlisted for the PEN/E.O. Wilson Literary Science Writing Award One of Nature's Summer Book Picks One of Publishers Weekly's Top Ten Spring 2013 Science Books For centuries, we've toyed with our creature companions, breeding dogs that herd and hunt, housecats that look like tigers, and teacup pigs that fit snugly in our handbags. But what happens when we take animal alteration a step further, engineering a cat that glows green under ultraviolet light or cloning the beloved family Labrador? Science has given us a whole new toolbox for tinkering with life. How are we using it? In Frankenstein's Cat, the journalist Emily Anthes takes us from petri dish to pet store as she explores how biotechnology is shaping the future of our furry and feathered friends. As she ventures from bucolic barnyards to a "frozen zoo" where scientists are storing DNA from the planet's most exotic creatures, she discovers how we can use cloning to protect endangered species, craft prosthetics to save injured animals, and employ genetic engineering to supply farms with disease-resistant livestock. Along the way, we meet some of the animals that are ushering in this astonishing age of enhancement, including sensor-wearing seals, cyborg beetles, a bionic bulldog, and the world's first cloned cat. Through her encounters with scientists, conservationists, ethicists, and entrepreneurs, Anthes reveals that while some of our interventions may be trivial (behold: the GloFish), others could improve the lives of many species-including our own. So what does biotechnology really mean for the world's wild things? And what do our brave new beasts tell us about ourselves? With keen insight and her trademark spunk, Anthes highlights both the peril and the promise of our scientific superpowers, taking us on an adventure into a world where our grandest science fiction fantasies are fast becoming reality.

Book Description
Hello, and welcome to the ever-wonderful field of aquariums. Thank you for allowing me to share with you the basics of goldfish care. You will find that though they've been human pets for centuries, and often referred to as "easy to keep", modern Goldfishes are quite different than commonly perceived. These minnows require a good deal more room than bowls can provide, attention to filtration, restraint in not over-feeding, and regular upkeep of their systems water quality. Not to worry; all will be revealed here.
