Legislators Debate the Oyster Fishery

Oysters are supposed to live on elevated bars, not flat on the bottom like a carpet. Over time destructive harvesting practices have flattened almost all of the three demensional structure created by oysters so they are suceptable to siltation. A goal of sanctuary development has to be re-creating 3D structure in places that won't be silted over.

Perhaps..although the oysters in the mud flats off my shore seem to do fine. But I digress and I'm certainly not a marine biologist..haven't even stayed at a Holiday Inn recently. But IF..and knowing the topography of the river bottom pretty well I am not sure that's not a big if..if '3-D oyster bars' are essential to their survival and growth, how would such massive underwater structures be created? Naturally...artificially..both?

Oysters are like coral, they grow on top of eachother to create a reef.

With the loss of almost all 3-D structure, humans have to give them a jumpstart. This can be done with piles of shell, rock, rubble, etc.

Check out this Army Corps Project on the Great Wicomico - in VA. They elevated the oysters 12" and have seen the most significant short term recovery ever observed (we'll have to wait and see for the long term).

Good stuff. Well I sure do wish them (the oysters AND those whose livelihood depnds on them) luck. Maryland's track record in oyster restoration is less than sorry. Lot of money wasted for zero gain...and I sat and literally watched them do it; had a front row seat.

I work in shipbuilding and spent a lot of time around the southern coast of South Korea and adjacent islands. The oyster aquaculture method they use there is on a truly massive scale..the white floats that support the oyster 'strings' extending in thick bunches for as far as the eye can see in the more sheltered coastal areas. I would rather not see that method employed here..but it proves that there are methods that work and are very economically viable.
