  abstract = {{S}everal methods are used for age determination of eels in the {F}rench mediterranean lagoons (observation of the whole otolith after clearing, grinding and polishing, dyeing, {SEM} and image analysis). {T}wo types of otoliths are observed depending on the width of the growth rings which is probably related to the environmental conditions. {F}urthermore, the growth checks are located nearby or inside the opaque rings. {A} computer assisted method is developed, with reference to the other methods, with the aim of improving the efficiency of collecting and processing age and growth data. {W}ith further developments and increasing knowledge of life-history of elvers and juvenile eels, it seems possible to use an image analysis system for ageing eels in lagoons. {N}evertheless, the most important point is to validate the results before using them for growth populations studies.
