Report of the Ad-Hoc on the Field Training Course on Otolith/Spines Sectioning and Age Reading
Piraeus, Greece 19-23 July 2010
Abstract
The ad-hoc on the field training course on otolith/Spines Sectioning and age reading was held in Athens, Greece from the 19th to 23rd of July 2010. It was organized with the specific purpose of introducing the basic knowledge on the most common techniques and equipment necessary to estimate fish age and growth through the analysis (or reading) of otoliths and other bony structures. This was considered as a first step towards the harmonization of national expertise in the field of age and growth studies. The training course was divided into several sessions, during which it was possible to focus on the main aspects regarding the age estimation of fish species, from the setting up of the laboratory equipment to the age estimation of selected specimens and the estimation of growth parameters.
