| Abstract: | This paper is based on the 2231 specimens of scaled sardine (Harengula zunasi) collected through the year 1988. The scales were read for the ages (age 1-6), and were 'further analysed using electronmicroscope. The Von-Bertalanffy growth parameters were calculated. The population structure, life history and mortality were investigated for the species. This could be useful for the fisheries management of the scaled sardines. |
