In wild populations, this larviparous protandric hermaphrodite exhibits asynchronous gonadal maturation and relatively low fecundity.
By contrast, Ostrea chilensis is a larviparous protandric hermaphrodite that first achieves sexual maturity as a male, but subsequently the majority of individuals produce both male and female gametes, a feature commonly observed in other oviparous ostreids (Buroker et al.
Such baseline information is crucial for establishing selective breeding programs for this protandric, hermaphroditic, and larviparous species.
As reported by Coe (1931b), Ostrea lurida is a protandrous, sequential hermaphrodite, viviparous, and larviparous. Gametes from both sexes are commonly found simultaneously in the gonad follicles (Coe 1931b, Oates 2013).
The European flat oyster is a larviparous, protandric hermaphrodite wherein asynchronous spawns and variable sex ratios can lead to loss of genetic diversity and inbreeding depression within hatchery populations as a result of disproportionate gametic contributions in mass matings.
Negative effects of inbreeding on larval survival in hatcheries have been reported for various species of bivalves, with larviparous species such as Ostrea edulis being particularly susceptible (Bierne et al.
