Report of the Workshop on Age reading of Horse Mackerel, Mediterranean Horse Mackerel and Blue Jack Mackerel (WKARHOM)

Based on the previous work of WKARHOM2 (2015), the Working Group on Biological Parameters (WGBIOP 2017) identified the need for a new otolith exchange followed by an age reading Workshop. The Workshop on Age reading of Horse Mackerel, Mediterranean Horse Mackerel and Blue Jack Mackerel (Trachurus trachurus, T. mediterraneus and T. picturatus) (WKARHOM3) was held in Livorno (Italy) from the 5th to the 9th November 2018. The meeting was co-chaired by Alba Jurado-Ruzafa (Spain), Kélig Mahé (France) and Pierluigi Carbonara (Italy), and included fifteen age readers from nine countries.
