In 2009, I went to Puget Sound to film sustainable oyster farming at Taylor Shellfish. Those short videos are to be found on the You Tube channel of marketumbrella.org. The company works with small oyster growers like the amazing Evan and John Adams of Sound Fresh Oysters who have varieties that they only bring to the Olympia Farmers Market.
Taylor also grows their own and encourage home growers with a waterfront oyster garden kit that they sell one day a month, to help people understand how oysters develop. (Go to the Go Fish chapter and look for the oyster videos.)

I have never forgotten how the Taylors (and Oyster Bill!) build the future of their ecosystem with their techniques and can only hope that some of their innovation can rub off on my own oystermen of Southeastern Louisiana so we can save our dying oyster industry here.
However, the issues are constant, and one grave threat is explained in the article link. When will environmental destruction finally hit home for humans? What amount of food will we have to lose before we address it?
