Download or read book Settlement and Postlarval Ecology of the Red Abalone Haliotis Rufescens in Culture Systems written by and published by . This book was released on 1999 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several studies on abiotic and biotic factors that may influence metamorphosis induction and early postlarval survival and growth of the abalone Haliotis rufescens (Mollusca: Gastropoda) in culture systems were conducted. The availability of appropriate cues for metamorphosis induction is crucial. The conventional cue provided in abalone culture (diatom films) is inadequate for this species. This study shows, for the first time, that the gamma-aminobutyric acid (GABA) can be used successfully in massive-scale conditions. Metamorphosis induction by this amino acid was 75-76% (after 24 h) while only 8-12% larvae responded to diatom films. Bacterial interference can be minimized by exposing larvae to GABA in clean tanks and adding diatoms (and associated bacteria), as a postlarval food, after metamorphosis is induced. Alternatively, the conventional GABA concentration (1 micromolar) may be increased within safe limits (up to 2-3 micromolar) to cope with potential degradation of the amino acid by bacteria. Another important factor is the timing of settlement, since a suboptimal induction occurred in precompetent larvae or after a prolonged delayed metamorphosis. However, a maximum response to GABA and increased early postlarval development were observed for larvae settling 1-3 days after the onset of competence. Although GABA is now routinely used to improve settlement in many H. rufescens hatcheries, high mortality or slow postlarval growth are still common. Ecological conditions in the benthic boundary layers above diatom-films of culture systems may play an important role on postlarval fitness. Oxygen microgradients within 1 mm above biofilm surfaces were observed in laboratory studies, with bottom levels higher than 180% or lower than 50% saturation in light and dark conditions, respectively. Reduced postlarval survival and growth can also result from the depletion of biofilms after excessive grazing. Thus, information on grazing rates and the factors controlling them is crucial for the optimal management of culture systems. This contribution provides the first estimates of grazing rates of H. rufescens postlarvae, based on the digital analysis of video-recorded images, ranging from 20 to 724 diatom cells/individual/hour during the first month after settlement.

Download or read book The Pearl Oyster written by Paul Southgate and published by Elsevier. This book was released on 2011-08-19 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contrary to a generally held view that pearls are found by chance in oysters, almost all are now produced from farms. This book is a comprehensive treatment of all aspects of the biology of pearl oysters, their anatomy, reproduction, genetics, diseases, etc. It considers how they are farmed from spawning and culturing larvae in hatcheries to adults in the ocean; how various environmental factors, including pollution affect them; and how modern techniques are successfully producing large numbers of cultured pearls. This is the ultimate reference source on pearl oysters and the culture of pearls, written and edited by a number of scientists who are world experts in their fields. - Comprehensive treatment of pearl oyster biology and pearl culture - Written by the top world authorities - Highly illustrated and figured - Of practical relevance to a broad readership, from professional biologists to those involved in the practicalities and practice of pearl production

Download or read book On Food and Cooking written by Harold McGee and published by Simon and Schuster. This book was released on 2007-03-20 with total page 898 pages. Available in PDF, EPUB and Kindle. Book excerpt: A kitchen classic for over 35 years, and hailed by Time magazine as "a minor masterpiece" when it first appeared in 1984, On Food and Cooking is the bible which food lovers and professional chefs worldwide turn to for an understanding of where our foods come from, what exactly they're made of, and how cooking transforms them into something new and delicious. For its twentieth anniversary, Harold McGee prepared a new, fully revised and updated edition of On Food and Cooking. He has rewritten the text almost completely, expanded it by two-thirds, and commissioned more than 100 new illustrations. As compulsively readable and engaging as ever, the new On Food and Cooking provides countless eye-opening insights into food, its preparation, and its enjoyment. On Food and Cooking pioneered the translation of technical food science into cook-friendly kitchen science and helped birth the inventive culinary movement known as "molecular gastronomy." Though other books have been written about kitchen science, On Food and Cooking remains unmatched in the accuracy, clarity, and thoroughness of its explanations, and the intriguing way in which it blends science with the historical evolution of foods and cooking techniques. Among the major themes addressed throughout the new edition are: · Traditional and modern methods of food production and their influences on food quality · The great diversity of methods by which people in different places and times have prepared the same ingredients · Tips for selecting the best ingredients and preparing them successfully · The particular substances that give foods their flavors, and that give us pleasure · Our evolving knowledge of the health benefits and risks of foods On Food and Cooking is an invaluable and monumental compendium of basic information about ingredients, cooking methods, and the pleasures of eating. It will delight and fascinate anyone who has ever cooked, savored, or wondered about food.
