Objective | The Bay of Biscay and the Celtic Sea are a major fishing sector for French fleets. The economics stakes for this vast area fully justify a major effort in terms of managing the resource and making arrangements for these fisheries, which will require in depth knowledge of the biology and dynamics of the fished stocks. Therefore, it is essential to have reliable time series for the parameters needed to assess the resources and trends of marine ecosystems. The EVHOE cruises act as an observatory for resources in the Bay of Biscay and the Celtic Sea. Populations are inventoried annually, following a standardized protocol. The EVHOE cruises are part of the Ecosystem approach to fisheries programme and their main objectives are to construct time series of abundance indexes which can be used in stock assessment and which can measure the annual recruitment of populations; studying strategies of how species occupy space over their life cycle. In addition, the EVHOE project is a source of information about how demersal and benthic resources evolve, for IFREMER's scientific challenge entitled "Understanding the interaction between fisheries resources, the environment and pressure from human activities on the regional scale, analyzing, understanding and predicting how the system will evolve according to various climate and economic scenarios". |
