Summary:

Mass oyster mortalities have been known for many years throughout the world, but no strictly pathological explication has been found. This book describes how environmental influences, reproduction, stress, genetics, pathogens and temperature contribute to oyster summer mortality in France. An interaction model is derived from the results and recommendations are made for forecasting and managing risk factors. The French version of this book, Mortalités estivales de l'huitre creuse Crassostrea gigas, is available on our website. La version française de ce titre, Mortalités estivales de l'huitre creuse Crassostrea gigas est disponible sur notre site.
