Abstract

Age and growth of the speckled shrimp Metapenaeus monoceros have been studied using von Bertalanffy growth model in two ways (1) by applying the modal progression analysis, Land K estimated by Ford - Walford method and to estimated by Gulland method, so as to facilitate comparison of the present results with earlier growth studies and (2) by application of ELEFAN I method. It has been observed that the results on growth obtained by these two procedures are almost similar at the end of 18 months. The L_ and K (annual) values of M. monoceros estimated by ELEFAN I method are 204 mm and 1.8 for females; 170 mm and 1.5 for males respectively. The total length attained by females and males respectively are 113 and 84 mm at the end of 6 months, 167 and 129 mm at the end of 12 months and 189 and 151 mm at the end of 18 months.
