Spawning migration of the european eel: reproduction index, a useful tool for conservation management

The European eel Anguilla anguilla is a common fish species in West European countries supporting several thousands of small-scale fisheries. In June 2008,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 decline 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 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. First time that quality parameters of eels are presented in book form Discusses causes for collapse of eel population Provides information on eel migration crucial for eel conservation regulation
