I have approximately 4000 oysters behind the house in our creek (in taylor floats) that are market size now. I have been growing them nearly 3 years. I will probably buy several thousand oyster seed (baby oysters) this year and expand my "garden". I have given a few oyster gardens as presents because whether the people eat the oysters later or not, they still need to grow and to do so, they are great filters. I think that everyone on the water that can, should grow some oysters, I think that when I get the small seed it's something like $25/1000count. Last year at Christmas I went and harvested a bunch of the biggest ones for the family. This spring, I noticed a significant increase in my numbers as they must have spawned and a lot of the spat settled in the same floats... a lot obiously went out with the tide as well, which has always been my hopes.
I've considered taking the oysters out to the artificial reef sites and dumping overboard or to other locations like the sand bar in front of the house (though that would probably get harvested by a waterman). For aquaculture of oysters there you can get the kind that reproduce and a kind that doesn't (both eastern oysters by the way), I of course have the kind that reproduce. Chesapeake Bay Foundation does will give you oysters to grow for a year if you bring them back to them to put in the bay, I have never gone this route because I have not determined if I will eat them or not... or some... or whatever. But I may get a thousand or so from them and grow them in addition to mine.
The steps taken this year to put a moritorium on the winter blue crab dredge in the Chesapeake Bay as well as a few other restrictions have (from what I have seen) dramatically increase the number of Blue Crabs (again, this is from what I see, not from any scientific research). I hope that the winter dredge continues to be something from the past that we never go back to.
I'm not a crazy greeny, I enjoy fishing and catching my own food from the bay, but those spending time on the bay year after year can see the changes happening. In fact, I get pretty irritated that they will tighten regulations on recreational fishermen and not commercial fishermen but they have a strong lobby I guess.
