Grands invertébrés et poissons observés par les campagnes scientifiques. Bilan 2007

The ecosystems exploited by fishing are complex. The species which are sought after and their distribution rely on numerous processes, in time and space. The understanding of marine ecosystems requires important means and diverse information including those of professional fishing and scientific cruises. At first, scientific fishing cruises aimed to explore marine fauna and discover new halieutic resources. They were in line with the exploration cruises carried out by Prince Albert 1st of Monaco at the end of the XIXth century. However, since the beginning of the 1970s, they have been focusing on the quantification of the resources exploited by fishing. [...] After a series of "Understanding keys" aimed at helping the reader understand the methodology and indicators used, this bulletin provides a synthetic card for each studied area. Each index card is divided into two parts. The first part presents the temporal evolution of the populating indicators, gives the tendencies when they are of any significance, describes the specific line-up of the populations and classifies them according to a number of tendency scenarios based on various indicators. The second part presents the biogeographic and human elements which can be of some help in the interpretation of the indicators.
