Larvae production by Ostrea puelchana was studied in collections obtained from November to March 1977-78 and 1978-79. During the first period there seems to be a direct relation between the highest percentage of gravid female and the moon crescent quarter. This relation is not repeated in the following year. Compared with other larviparous oysters, O.puelchana produces a greather number of embryons of smaller size, with shorter breeding period and longer planktonic life.
