Oysters with checkered pattern shell
I learned something about oysters this weekend. In an experiment designed to test durability of aquaculture equipment, some stray oysters attached to the outside of a plastic mesh. I noticed that all of the oysters adopted a mesh pattern on their top side even though that was not touching the plastic mesh.
Similarly, I’ve noticed that oysters growing on ribbed mussels are more likely to show longitudinal ribs. Until now, I just thought it was due to a protected growth pattern. There must be something published somewhere on this topic, but I haven’t found it yet. Nor do I know of any practical application of this observation. But I’ll keep an eye on the checkered oysters to see if the pattern remains as they continue to grow.
Photos are pasted below:

New Facility to Help Chesapeake Bay Oyster Restoration
Horn Point Labs in MD is clearly the east coast leaders in oyster restoration. This approach would also be effective for New Jersey but current politics to protect the status quo in the oyster industry rather than allow restoration prevent the development of a similar facility here. Smaller hatcheries, including my own, have been successful in gthe Delaware Bay but all have now been cosed down under pressure.
