When can my baby eat shellfish? Shellfish can be a healthy part of your child's diet soon after she begins to eat solid food, usually when she's around 4 to 6 months. But if your baby has chronic eczema or a food allergy, talk to the doctor first before giving your baby shellfish.
The oyster spat will start to feed and put all of their energy into shell growth by sequestering calcium carbonate from the water column. 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.
