That's why I am interested!

I wanted to throw one more fact into the mix...
In August 2009, the EIS that studied the restoration of Chesapeake Oysters, and the possible introduction of the Asian Oyster was finalized. After 6years of study, (and $17M) the final reccomendations were - 1) native oysters only. 2) Temporary Harvest moratorium. 3) Transition to aquaculture production. 4) Ramp up restoration.

With oysters being so critical to the bay's ecology, I'd prefer a permanent buyout. Infact, the EIS also recommended that.
Or
A heavy subsidy for those that wish to transition to oyster aquaculture.
Unfortunately with the oyster population at 1% of their historic abundance, even if we stop harvesting them completely, they won't come back without tremendous public investment, and it's going to take a very long time. Possibly 20 years or more.
Surely we can't restore the oyster population to what John Smith saw (reefs that jutted out of the water and were hazzards to navigation), but even if get 20% there, the benefit will be manyfold because they filter the water and provide habitat for fish and crabs.
I would argue that the benefit to other fisheries and economies that rely on the bay (fish and crab industries, sportfishing, etc) would be worth the cost of the permanent abandonment of an oyster fishery that relies on harvesting oysters off public bottom.
Combine that with an aquaculture based oyster industry, and you have the best of both worlds.
Unfortunately, it's not that simple of a problem!
If the problem were to simply provide enough oysters for oystermen to catch, it would be much easier. Unfortunately the problem is that our bay is polluted, and oysters are one of the few things that can help clean it up. A single adult oyster can filter 50 gallons of water per day. Based on the status of the bay, we need every oyster we can get, and we need them to stay out there to filter water.
Truly, if there is an alternative to harvesting off public bottom - there really is no need to retain a fishery that depends on it. It's better for the state, the public, the health of the bay, and for the fishermen themselves if they create an aquaculture based industry.

I guess I am missing the alternative to harvesting off the bottom?
The alternative to harvesting off the public bottom is aquaculture.
Oyster aquaculture can be done in dozens of different ways.
Seeding a parcel of leased bottom, and waiting 2-3 years to harvest is just one method. It is the easiest (labor wise) but has the lowest return, and highest oyster mortality due to predators, disease, siltation, etc.
Other methods include floats (like at Circle C), racks, cages, bags, rafts, etc. All of these methods are similar becuase you protect the oysters from predators, and perform some level of maintenance to keep siltation and fowling from killing oysters or slowing their growth. This methods can produce market oysters in as little as 6 months.
Oysters could be grown in tanks, but it wouldn't really be cost effective because pumping water takes a lot of energy/electricity.
The current oyster fishery relies on harvesting oysters off public bottom that were seeded by the state. The subsidy for this easter egg hunt was 40 million dollars between 1994-2008. Despite the investment of taxpayer money the oyster industry still declined, and so did the overall population of oysters. This is clearly a failed strategy.
All very reasonable, except it places the short term needs to preserve a "way of life" above the long term needs of public to have a restored Chesapeake. We've spent 40 years subsidizing the oyster industry while trying to accomplish two goals: 1) Preserve the industry, 2) Restore the oyster population. Unfortunately the result has been a failure; we have a smaller oyster industry (nearly economically extinct) and fewer oysters.
That being said, an abrupt end to the oyster fishery could have some negative impacts if it's not combined with some type of buyout, but at some point we have to come to terms with the idea that oysters create habitat and filter water. We desperately need more habitat, and more water filtered in the bay. To me, this is ecological function is much more important than preserving a way of life.
The Chesapeake watermen's way of life is designed so that they aren't tied to one single resource. Oystering is a part-time job. As I showed above, nobody is making their living on oysters, and I doubt very few are even covering expenses. The loss of this fishery, provided there is some compensation, or assistance in transitioning to aquaculture for those who wish to give it a try, will not cause some great sociological loss. There will still be watermen, they'll just do things a little bit differently.
I also believe the benefits of a restored oyster population and an industry that relies solely on aquaculture production will be far reaching. Not only will there be more oysters filtering more water, there will also be more jobs on the water (in aquaculture). If we leave things alone, the jobs we have will be lost.
I think we only disagree on the idea that someday soon there will be enough oysters to satisfy a harvest on public bottom. Maybe I'm blinded by my views, but I just believe that hardbottom habitat created by oysters is too important to end up on a plate. Aquaculture can easily satisfy the market in Maryland, just as it does in many other states.
I agree that we really do need to seed oysters in the bay, but I believe it should be done for ecological benefits, not economic. If we can agree to that, as a state, the economic benefits will be realized later (more crabs, fish, better fishing, etc.)
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.
