PRESENTATION: Today research fishing can not be confined in a simple mono-specific management of exploited stocks, regardless of environmental variability and other species. The need to extend the knowledge on ecosystems is somewhat clearer than the fisheries management of the stock is sold to the ecosystem. This necessary evolution is based on the current state of world fisheries: about 75% of stocks are overexploited, catches reach 20 million tonnes, many species are endangered, fisheries have problems on -capitalization, etc. The finding of the current world situation imposes difficult to find alternative solutions in fisheries management. The effects of fishing not only reflective in exploited species but also throughout the ecosystem.

However fishing is only one factor active on aquatic communities. The search for a quantitative understanding of the dynamics of interactions between biotic and abiotic components of marine ecosystems is the foundation of modern fisheries oceanography.

The development of multispecies spatial modeling approaches that integrate the environment and exploitation, they need a link between environmental variability and spatial dynamics of fish stocks and their exploitation. A model is constructed often with historical and current knowledge. But, first, the image we have of the system changes with changes in the methods of in situ and, moreover, ecosystems themselves evolve over time. We must recognize that models are developed with accumulated knowledge in general a posteriori explanatory but not predictive of a satisfactory manner, and strong changes were observed but could be expected. For example acoustic observations showed simultaneous upheavals of ecosystems in different parts of the world. These disorders can get to the radical change in the behavior of animals, which can radically change its own characteristics eco-ethology: changing spatial strategy, type of aggregation, migration patterns, etc. This illustrates the way to go before we really understand the functioning and evolution of populations and ecosystems.

OBJECTIVES

 In this context, this course aims to provide theoretical understanding and analysis allowing inter-specific relationships and the effect of environment (biotic, abiotic and anthropogenic) on fish stocks . To achieve this objective will focus on various aspects: reproduction, recruitment, distribution, availability, catchability and fluctuations in abundance of short to long term. The course will be developed through the framework of an ecosystem approach and present some of the theories in fisheries ecology.
