Report of the workshop on the age estimation of sardine and sardinella in northwest Africa : Casablanca, Morocco, 4-9 December 2006 (FAO fisheries report)

The workshop reviewed and discussed the results of an otolith exchange that had been carried out in 2006 and which included both sardine and sardinella otoliths from different locations. The final outcome of the meeting consisted in revised agreed guidelines for the preparation and interpretation of sardine and sardinella otoliths. A new otolith exchange was initiated just after the workshop to consolidate results.
