The Working Group on Cephalopod Fisheries and Life History (WGCEPH) improves the knowledge and assessment of cephalopods as an exploited resource.

​​​​​​​​Cephalopods are important components of marine ecosystems as well as significant resources, especially for small-scale fisheries in Europe. Under the European Marine Strategy Framework Directive (MSFD), the marine environment is defined as a precious heritage that must be protected, preserved and, where practicable, restored - with the ultimate aim being to maintain biodiversity and provide diverse and dynamic oceans and seas which are clean, healthy, and productive. Thus, for promoting the sustainable use of the seas and conserving marine ecosystems, cephalopod biology, life history, and assessment has to be taken into account.

WGCEPH resumes specific cephalopod scientific efforts on disciplines such as cephalopod biology, ecology, fisheries, and assessment. 

Over the last five years, the group's terms of reference have been focused around:

  • Data compilation in order to have access to up-to-date data on cephalopod landings, directed effort, discards, and survey catch data
  • Monitoring of fishery trends to ensure that fisheries and stocks remain sustainable
  • Production of CPUE data series as first steps for a possible assessment given the need to promote sustainable cephalopod fisheries, the likely importance of cephalopods as indicators of climate change, and the importance as predator and prey species in marine ecosystems
  • Knowledge and understanding of fleet (metier) dynamics targeting cephalopods
  • The need to progress on biological basics, e.g. growth (where the highly flexible nature of growth patterns presents a challenge for fishery data collection)
  • Evaluation of Data Collection Framework (DCF) effectiveness in cephalopod sampling to determine whether DCF is delivering the information that is/would be needed to assess cephalopod stocks and to identify any shortcomings​
