In this study, the Life Table Method also known as the Cutler-Ederer life table technique, was introduced and practicability of this technique for determining life period of fish species of which natural mortalities were found by estimation using parameter of length weight relationships has also been searched. The aim of this study is to show that life table method used for human beings, can be also used to predict fish species. The data employed in the present study is that of scaldfish Arnoglossus laterna (Walbaum, 1792) (Pisces: Bothidae) obtained from the Aegean Sea. Life span of five years and its ages were directly taken into account in the table prepared by the data concerned. Consequently, according to the data estimated, the life expectancy of the species in the Aegean Sea is approximately 11 years. Furthermore, the number of individuals estimated to live more than 5 years from the scaldfish population including 1000 individuals was calculated to be some 970.
