Abstract
Data registered for the absolute and relative fecundity in the present study revealedthat E. chlorostigma is more fecund than E. areolatus. It was found that absolutefecundity has a direct relationship with the body length and weight. The relativefecundity for both the species does not delineate any particular pattern of variation. Thesex ratio for both the species was heterogeneous showing the domination of male overfemale in certain months while females outnumber males in other months. The gradualincrease in the value of gonado-somatic index from March to September (E. areolatus)and June to September (E. chlorostima) observed in the present study shows thematuration / development of ovum in the ovaries. The highest value of it for both thespecies was registered in the month of September. A sharp decline in October indicatesthe spawning period (releasing of eggs from the ovary) of the fish.
