The International Council for the Exploration of the Sea (ICES) is the world’s oldest inter-governmental organisation. Under the ICES umbrella, we coordinate our data collection with European partner institutions. In ICES working groups, we produce the basis for scientific advice on the sustainable use of marine living resources. The advice is developed in concesus and forms the basis for our service to policy makers and other clients.

Staff members of the Baltic Sea Fisheries Institute are active in many ICES expert groups and other bodies, most prominently in the „Baltic Fisheries Assessment Working Group“ (WGBFAS), the „Herring Assessment Working Group“ (HAWG), the „Baltic International Fish Survey Working Group“ (WGBIFS) and the „Working Group on Recreational Fisheries Surveys (WGRFS). All of these have been or are presently chaired by institute’s staff. The ICES president 2015-2018, the second German delegate (Council) and the German Advisory Committee (ACOM) member are all employees of the Baltic Sea Fisheries Institute.

Participation in ICES groups: 2015/2016
