The illicium (first dorsal fin ray) has become the standard structure for age estimation of black anglerfish (Lophius budegassa) in most of the European countries and the one used as a basis for stock assessment, after calibration exchanges among the age readers and workshops. However, the tendency in the past to not pay essential attention to the need to validate or corroborate the age estimation in some stocks has led to misunderstanding of their dynamics. Thus, the Atlantic black anglerfish stocks have not been annually assessed using age-structured models during the last years in ICES working groups due to problems with the data quality, including those coming from a biased illicia age estimation criterion. The same age estimation criterion is used for the Mediterranean black anglerfish. Evidence obtained in the last years, using alternative methodologies to the age 263 estimation, have shown a faster growth rate of black anglerfish. Some growth increments considered as ...
