The European eel Anguilla anguilla is a common fish species in West European countries supporting several thousands of small-scale fisheries. In June 2007, it has been listed in Annex B of CITES after the 99% decline in recruitment observed over the last decades. A European Council Regulation was issued on September 2007 to arrest the collapse of the eel stock. In this book, we discuss the factors that may contribute to the collapse of the European eel population. With respect to conservation measures two important aspects have to be considered: quality and quantity of escaping silver eels. Clearly, a poor condition of the silver eels can never be compensated by large numbers. Qualitative parameters were thus far hardly available for management applications. The main goal of this book is to provide useful quality parameters for migrating silver eels, indicating their contribution to recruitment. The process of migration and maturation also provides information about the natural conditions for eel reproduction. Therefore, this book will also be very useful for eel aquaculture; it may provide tools for reproduction as well as for suppression of precocious maturation. An integrative approach regarding eel maturation requires a combination of ecology and physiology. In this book we included both aspects, and we hope that this will contribute to the restoration of the European eel population.

Written by experts actively working in the area, this book provides a review of the major diseases of fish caused by protozoan and metazoan parasites. The new edition has been thoroughly updated since publication of the first edition in 1995. It covers recent advances in the understanding of fish diseases including the improvement of diagnostic techniques and understanding of phylogenetic relationships stemming from the application of molecular techniques. The book also contains more detailed information on pathogens that cause amoebiasis.
The threat of biological weapons has never attracted as much public attention as in the past five years. Current concerns largely relate to the threat of weapons acquisition and use by rogue states or by terrorists. But the threat has deeper roots--it has been evident for fifty years that biological agents could be used to cause mass casualties and large-scale economic damage. Yet there has been little historical analysis of such weapons over the past half-century. Deadly Cultures sets out to fill this gap by analyzing the historical developments since 1945 and addressing three central issues: Why have states continued or begun programs for acquiring biological weapons? Why have states terminated biological weapons programs? How have states demonstrated that they have truly terminated their biological weapons programs? We now live in a world in which the basic knowledge needed to develop biological weapons is more widely available than ever before. Deadly Cultures provides the lessons from history that we urgently need in order to strengthen the long-standing prohibition of biological weapons.
This book presents information on the causative organisms, epidemiology and clinical features of helminth infections encountered both in temperate and tropical zones. It enables the reader to reach an accurate diagnosis, select an appropriate chemotherapeutic agent, and judge alternative options for designing integrated, economic and sustainable worm control programs. Particular reference is made to helminth infections transmissible from animals to man. Typically human helminthoses (e.g. schistosomosis, lymphatic filarioidoses, etc.) are also included.
