Baby Oysters
Spawning takes a lot of energy out of the animals, but for many types of oysters, it's the last work they have to do as parents until the process starts again the next year. Once their sperm and eggs are released into the water, they meet to fertilize in the water and develop into larvae.
What is the life cycle of an oyster?
The oyster becomes a juvenile at one year of age, and officially becomes an adult at year three. Oysters typically grow up to an inch per year. This is dependent on salinity and the quality of the water column. In higher salinity areas, oyster will grow faster than in lower salinity areas.
How do oysters have babies?
During an oysters spawning season, the young male releases his sperm and the older females release their eggs. Sometimes up to hundreds of million eggs. One the met they develop larvae. Larvae takes 6 hours to develop and a few weeks to settle into another oyster shell or rocky place.
How many babies do oysters have?
To ensure the survival of their species, oysters respond to this threat by ejaculating ungodly numbers of sperm and eggs into the water (where the gametes mix and form oyster embryos). Every season, an adult female oyster can produce 50 to 100 million eggs.

Yes, that's right, at one point in their lives, oysters move freely and have an eye and a foot! At this point, the oyster needs to look for a surface to attach to. Oysters in the wild will attach to any hard substrate, including rocks, driftwood, piers and more. ... Once the oyster sets on a substrate, it is called spat.
Are oysters born with shells?
2. Newly spawned oysters only need the teensiest (as in, almost microscopic) bit of calcium carbonate to start growing their shell. Oyster larvae essentially “wrap” themselves around their few little individual molecules of calcium carbonate to get the shell started.
How long until oyster reaches maturity?
It takes 18 to 24 months for oysters to become adults or grow to market size, approximately 3 inches. Since growers only have a finite amount of land, they also only have a finite amount of oysters they can grow on their farm.
