How does the asexual reproduction of Mollusks happen?

Answer 1

After they are a year old, mollusks, such as oysters, will spawn as males. The next year they will spawn as females. When the waters grow warmer, it will cause a few of the oysters or other mollusks in a bed to spawn, and once these few spawn, it prompts the rest of the colony to spawn. Females are capable of producing up to 100 million eggs per spawn cycle, although that doesn't necessarily mean that that number will be spawned each time. Once the egg is fertilized, it will soon grow into a larvae. The larvae will then attach onto the shell of an adult oyster, or somewhere else they can attach, and grow into an adult oyster.
