In 1989 we were asked by Dr Vidar Wespestad (National Oceanographic and Atmospheric Administration. National Marine Fisheries Service. Alaska Fisheries Science Center. Seattle. USA) to prepare and convene a session at the 1992 World Fisheries Congress in Athens. Greece on computer appli cations in fisheries. We agreed that the idea was a good one and the computer session turned out to be very successful. The computer session was organized in three parts: training classes. informal demonstrations accompanied by posters. and oral presentations of scientific papers. We were both amazed by the high level of interest and the high quality of contributions presented at the paper session. Returning from the World Fisheries Congress. we suggested to the International Council for the Exploration of the Sea (ICES) in Copenhagen to hold a theme session on the topic 'Computers in Fisheries Research' at their statutory meeting the fol lowing year in Dublin. Ireland. The proposal was very positively received by ICES and we began organizing this new meeting with Dr John Ramster of the Ministry of Agriculture. Fisheries and Food. Fisheries Laboratory. Lowestoft. England. Based on our experience with the World Fisheries Congress. we expected a maximum of 15 titles would be submitted to the ICES theme session. Accordingly. the ICES symposium was originally allo cated one half-day time slot. The response we received from the call for papers. however. exceeded our most optimistic expectations. A total of 62 abstracts were submitted. Consequently.
