Reproductive cycle of Zidona dufresnei (Caenogastropoda: Volutidae) from the southwestern Atlantic Ocean

Gonadal development of Zidona dufresnei (Donovan, 1823) (Caenogastropoda: Volutidae) was studied over a period of two consecutive years, through analysis of gonadal tissue. Individuals were sampled monthly at the Mar del Plata area, Argentina. Gonadosomatic index was estimated for males and oocyte s...

Individuals were sampled monthly at the Mar del Plata area, Argentina. Gonadosomatic index was estimated for males and oocyte size was used to estimate the stage of gonadal development in females. The reproductive season in this species in the sampled locality extended from October to March (austral spring-summer).

In autumn, gonads were generally under atresia; during wintertime (June-August), they underwent a period of recovery that lasted until the spring months, when gametes were released again. Synchronism between both sexes was evident. Marked periods of spawning were followed by resorption periods and then a growing phase; it was very clear that reproductive seasonality was linked to changes in bottom water temperature.
