    Abstract

    The present study represents the first information on direct age determination based on band counts in the mesocardiac ossicle (gastric mill) and eyestalk, in Aristeus alcocki, Penaeus monodon, Penaeus indicus, Panulirus homarus, and Portunus sanguinolentus from India. The determination of growth bands is important in understanding the accurate age of a specimen for the effective management strategies for stock sustainability of the natural resource. Longitudinal sections of the eyestalk and meso-cardiac ossicle of the gastric mill were observed for growth band counts in all species except for P. homarus, where the growth bands were recorded only in the ossicle. Growth bands count five in females and four in males of A. alcocki, respectively. In the case of inshore prawns, two growth bands were observed in P. monodon and one growth band in P. indicus, five growth bands in P. homarus, and three in P. sanguinolentus.
