Reproductive cycle of the sea cucumber Psolus patagonicus Ekman 1925, off Mar del Plata, Buenos Aires, Argentina

The reproductive cycle of Psolus patagonicus Ekman 1925 was studied. The species exhibits an annual reproductive cycle with one reproductive period in austral summer (February-March). During spring and summer, females showed the highest gonad-index (GI) values, while the GI values of males did not v...

During spring and summer, females showed the highest gonad-index (GI) values, while the GI values of males did not vary significantly throughout the year. Males had higher GI values than females. Maximum oocyte diameters ranged from less than 300 μm in spring to 900 μm in summer.
