Résumé

A critical examination of the periodic markings on otoliths has helped to establish that the markings could be used for the estimation of age and growth ofA. nebulosa. The relationship between the otolith radius and total length of the fish has been determined, based on which a formula for back calculation of lengths at different ages is derived. A study of the otolith margins has shown that the formation of the translucent bands is annual in nature. A von Bertalanffy growth equation has been fitted to the data and it is found that, in the size ranges studied, this growth equation adequately describes the pattern of growth of the eel. Earlier studies on the age and growth of the eel are discussed and a comparison with growth of other species of eels of the same genus has been attempted.
