Abstract

The results of the studies on age and growth of Metapenaeus affinis, one of the dominant species of penaeid shrimps in the coastal waters off Maharashtra are presented. From monthly size-frequency data, the growth parameters for males and females were estimated employing modal progression and computer based FiSAT software package using ELEFAN program, Bhattacharya method, Gulland-Holt plot, Faben’s method, Appeldoorn’s method and von Bertalanffy plot. The estimates obtained by Bhattacharya analysis and Gulland-Holt plot were: L = 162 mm, K = 2.25 for males and L = 204 mm, K = 1.91 for females. Males and females were found to attain 145 mm and 174 mm at the end of one year and their life spans were 1.16 and 1.4 years respectively.
