title: Gametogenesis in the freshwater prawn, Macrobrachium lamerrii.
abstract: Histological changes of the female and male gonads were studied and their relation to reproductive cycle is described. Ovary showed distinct changes during the course of its reproductive cycle. Maturational changes did not occur simultaneously in all follicles of the ovary. Regression of ovary during the non breeding season with a number of degenerating oocytes was observed. The seasonal changes in spermatogenesis revealed that growth in the testes appeared to be less than in the case of females.
