Part 2 of the ICES Annual Report for 2000, ICES Council Resolution C.Res. 2001/2G02 stated that the Working Group on Cephalopod Fisheries and Life History [WGCEPH] (Chair: Dr .J.P. Robin, France) would meet in Rome, Italy from 10-12 April 2002 to: a) update currently available landing statistics and information on fishing effort and discards; explore existing resource survey databases for information about sampled cephalopods in the ICES area; b) compile methods and results available for stock identification and estimation of population size of fished cephalopods; c) compile available data on gear selectivity for cephalopods; d) identify possible precautionary approaches to the management of cephalopod resources; e) compile available data on relationships between abundance and environmental conditions, factors affecting recruitment, migration and distribution patterns of juveniles and adults, and trophic interactions; f) update the bibliographic database of cephalopod literature relevant to fisheries, including grey literature; WGCEPH will report by 30 April 2002 for the attention of the Living Resources Committee, and ACFM and ACE. 1.2 Attendance The WGCEPH meeting at the ICRAM headquarters, Rome, 10-12 April 2002, was attended by 8 of the currently appointed WGCEPH members.
