Sea urchins and sea cucumbers are highly sought after delicacies growing in popularity globally. The demand for these species is rapidly outpacing natural stocks, and researchers and seafood industry personnel are now looking towards aquaculture as a means of providing a sustainable supply of these organism. Echinoderm Aquaculture is a practical reference on the basic biology and current culture practices for a wide range of geographically diverse echinoderm species. Echinoderm Aquaculture begins by examining the basic ecology and biology of sea urchins and sea cucumbers as well as the breadth of uses of these organisms as a source of food and bioactive compound. Subsequent chapters delineate the specific species of interest invarious geographic regions from around the world. Together, chapters provide a comprehensive coverage of culture practices. Echinoderm Aquaculture is a practical reference for researchers and industry personnel, and will serve as an invaluable resource to this rapidly growing segment of the aquaculture industry.
A playwright, a journalist, and a stunningly beautiful drag-queen prostitute. In this fascinating memoir, Eddie Woods brings all three together. And along the way graces us with countless insights into the heart and mind of one of America's greatest dramatists. Even while paying homage to his beloved Kim, the most unique of his many lovers. As well as regaling us with numerous other tales of his more than two years in the City of Angels. Wherever he is, Tennessee Williams is smiling at this book. Now you can smile with him.
Sea urchin eggs are objects of wonder for the student who sees them for the first time under the microscope. The formation of the fertil ization membrane after insemination, the beauty of mitotic cleavage, the elegant swimming of embryos, remain an esthetic pleasure even for the eyes of seasoned investigators. But sea urchin eggs have other, more practical, advantages: they lend themselves to surgical operation without difficulty and they heal perfectly; they can be obtained in very large amounts and represent thus an extremely favorable material for biochemists and molecular embryologists. It is not surprising that, in view of these exceptional advantages, sea urchin eggs have attracted the interest of innumerable biologists since O. HERTWIG discovered the fusion of the pronuclei (amphimixy), in Paracentrotus lividus, almost a century ago. The purpose of the present book is to present, in a complete and orderly fashion, the enormous amount of information which has been gathered, in the course of a hun dred years of sea urchin embryology. JOSEPH NEEDHAM, in 1930, was still able to present all that was known, at that time, on the biochemistry of all possible species of developing eggs and embryos in his famous "Chemical Embryology" (Cambridge University Press) . It would no longer be possible for one man to write a modern version of what was a "Bible" for the young embryologists of forty years ago.
Provides an understanding of British fish, from their natural habitats to what sauce they go best with to how to respect their seasonality, in keeping with the River Cottage ethos. This book explains the ins and outs of procuring a good fish, as well as how to buy and catch fish in an ethical way, and how to prepare it for the kitchen.
This book provides a practical guide to experimental methods for studying the development of invertebrate deuterostomes, such as sea urchins, ascidians, hemichordates, and amphioxus. These model organisms are of contemporary and historical importance to the study of developmental biology, particularly genomic research. The chapters provide detailed experimental protocols that cover a broad range of topics in modern experimental methods. Topics covered range from rearing embryos to the care of adult animals, while also presenting the basic experimental methods including light and electron microscopy, used to study gene expression, transgenics, reverse genetics, and genomic approaches. * Covers a wide range of methods, from classical embryology through modern genomics * Discusses animals related to vertebrates, providing a valuable evolutionary perspective * Includes a practical guide to the use of sea urchins in the teaching laboratory
This book should be regarded as the continuation to my previous book Developmental Biology of the Sea Urchin Embryo, edited by the Academic Press in 1973, rather than as a new edition. Due to the exceedingly high rate of development in this field (something like 2000 papers have been published on this subject in these last 10 years), I preferred, in fact, not to describe again in detail the enormous amount of the old literature, as was attempted in my previous book, but to briefly summarize the state of the art in each problem and to describe in some detail the experiments per formed in the last 12 years. In doing so, more emphasis was given to the more recent ones and to those which can be considered as corner stones in each subject. Care was, however, taken to mention the reviews or key papers in which the reader can find a source of the details of the older literature, besides refering him to my previous book.
Echinoderms, the star fish skeletons that beachcombers collect, are brilliantly colored and intricately ornamented creatures in their natural habitat. This reference features over 130 color photographs of five classes of echinoderms (sea stars, brittle stars, sea urchins, feather stars, and sea cucu
When career-girl Veronica flies to Sicily for a friend's wedding, she accidentally falls in love with one of the groom's three-hundred cousins. A year later she has given up her job, house and friends, and is planning her own wedding with her Latin Lover in the shimmering heat of Sicily.
Sea urchins play a key role in marine ecosystems, controlling through its grazing activity the dynamic, structure and composition of seaweed and sea grasses. Moreover, it is a crucial component of the food web, as prey for fishes and other marine animals. Due to its sedentary habits and sensitivity to pollutants, adult sea urchin has been used in several studies as a biological-biochemical indicator of local pollution. This book provides several topics on sea urchins. It discusses the phenotypic variation and resilience in sea urchin morphogenesis; response of sea urchins to environmental stress; nonparametric regression applied to sea urchin growth; and sea urchin immune systems.
