Objective

The Bay of Biscay and the Celtic Sea are a major fishing area for French fleets. The economic importance of this vast area fully justifies a major effort in terms of resource management and fisheries management, which requires a thorough knowledge of the biology and dynamics of the stocks exploited. It is therefore essential to have reliable time series of the parameters needed to assess marine ecosystem resources and trends.

The EVHOE campaigns serve as an observatory of the resources of the Bay of Biscay and the Celtic Sea. The population census is carried out annually according to a standardised protocol. The EVHOE campaigns are linked to the Ecosystem Approach to Fisheries programme and their main purpose is to:

  • constitute time series of abundance indices, which can be used in stock assessment and in particular to measure the annual recruitment of populations,
  • study the strategies for occupying species' space during their life cycle.

In addition, the EVHOE project is a source of information on the evolution of demersal and benthic resources for the IFREMER scientific challenge entitled: "Understanding the interaction between fish resources, the environment and human pressure at the regional level, analysing and predicting the evolution of the system under various climate and economic scenarios".
