WK See 1997 WK report - Prior to this exchange, a Workshop was held in June 1994. The main conclusions and recommendations of this Workshop were (Anon, 1994a, 1994b; Carrera, 1996):1. the ageing criteria established in FAO (1979) were still valid and should continue to be used by both countries;2. in order to reduce the discrepancies in age group determinations, the number of otoliths sampled should be increased, mainly for sardines of higher lengths.3. otoliths should be exchanged regularly between both countries;4. efforts should be focused on the characterisation of the otolith margin in order to perceive its pattern deposition and thus getting information about the validation of the annual growth pattern and, consequently, on the age group assignment; Anon, 1994a.

WK A workshop on herring age reading and determination of spawning time was held at the Danish Inst Fisheries Research, Charlottenlund, during last week (14 Jun 2002 ). The meeting aimed at reaching higher agreement in age and spawning time determination among the different institutes, which are either involved in one of the ICES herring working or planning groups (and delivering age-structured data to the herring assessments), or in the EU project Hergen. http://www.clupea.net/news/index.html
