Medaka: Biology, Management, and Experimental Protocols, written by experienced researchers and reviewed by international leaders in the medaka field will provide details on how to set up and maintain medaka colonies in animal facilities, how to troubleshoot systems, how to handle the fish when applied to experimental methods, and most importantly it will introduce the researcher to cutting edge research in basic and applied biology using medaka as a model animal. The book will include well-written descriptions of experimental methods and protocols designed to educate the reader how to understand and handle medaka effectively. Medaka: Biology, Management, and Experimental Protocols will serve as the definitive reference on the species providing essential information on medaka biology, genetics, and genomics, practical guidance to maintenance of fish stocks, and valuable experimental protocols all in a single volume. This book will be a must have addition to the library of fish researchers and those using medaka as a model organism within their laboratories.
In the compiling of this book, the vast literature dealing with the descriptive morphology, histology and cytology of teleost development has been combed and integrated. The book is divided into 21 chapters, starting with the egg and embryonic development up to hatching. This is followed by a description of ectodermal, mesodermal and entodermal derivatives and the development of various organs. The subject index, species index and the abundant illustrations add extra value to this long awaited book. Developmental Biology of Teleost Fishes will be a valuable tool for scientists and students in the fields of biology, developmental biology, molecular biology and fish biology.
The efficient and profitable production of fish, crustaceans, and other aquatic organisms in aquaculture depends on a suitable environment in which they can reproduce and grow. Because those organisms live in water, the major environ mental concern within the culture system is water quality. Water supplies for aquaculture systems may naturally be oflow quality or polluted by human activity, but in most instances, the primary reason for water quality impairment is the culture activity itself. Manures, fertilizers, and feeds applied to ponds to enhance production only can be partially converted to animal biomass. Thus, at moderate and high production levels, the inputs of nutrients and organic...
Fish culture in hatcheries and other aquacultural facilities is becoming much more intensive all over the world. The success of all kinds of fish rearing depends on the quality of management and this depends, in turn, on understanding the biology of fishes and the aquatic environment in which they live. This book directly addresses the relationship between the aquatic environment and the fishes. An understanding of this by the reader will result in a reduction of disease outbreaks through improved management.
Current growth in global aquaculture is paralleled by an equally significant increase in companies involved in aquafeed manufacture. Latest information has identified over 1,200 such companies, not including those organizations in production of a variety of other materials, i. e. , vitamins, minerals, and therapeutics, all used in varying degrees in proper feed formulation. Aquaculture industries raising particular economically valued species, i. e. , penaeid shrimps and salmonids, are making major demands on feed ingredients, while relatively new industries, such as til apia farming, portent a significant acceleration in demand for properly formulated aquafeeds by the end of the present dec...
As online education becomes more familiar, so the reality of using it in teaching and learning has moved beyond the realm of the specialist. Pedagogy and best practice Delivering Learning on the Net explores the reality of online education today. Martin Weller chaired the groundbreaking Open University course You, Your computer and the Net, which is now the largest for-credit online course in Europe. Based on this and his experiences elsewhere, the book is a comprehensive resource grounded in practical reality as well as in research. Key issues covered include: *the Net and its relation to education; *developing and implementing online courses; *the key issues surrounding online education. Teachers, trainers, technologists, administrators and decision-makers working in higher and further education will all find much of value in this book.
