How does the geoduck reproduce?
Geoduck reproduction is a complex and intriguing process that has fascinated marine biologists for centuries. During the spawning season, geoducks release sperm into the water column, while females release eggs simultaneously, a process known as broadcast spawning. The fertilized eggs then settle on the seafloor, where they undergo metamorphosis, eventually developing into juveniles. This process typically occurs between March and May, with peak spawning activity observed in April. Interestingly, geoducks can release millions of gametes during a single spawning episode, increasing the chances of successful fertilization. After settlement, geoduck juveniles go through a series of molts, gradually increasing in size and eventually reaching maturity, typically between 5 to 7 years. This remarkable reproductive strategy enables geoducks to thrive in their native habitats, from shallow bays to coastal waters, and has contributed to their status as a prized delicacy in many coastal cultures.
