Well, not really with my 'tanks,' but definitely in the realm of 'aquaculture' ...
I have been cultivating oysters on my beach since the summer of 2018. I have three batches of seed from Taylor Shellfish Farms distributed amongst 10 grow bags, shown here tethered to the beach, at low tide. There are ~1200 oysters of various ages in these bags at present.
Yesterday I finally had my first harvest- a half dozen oysters grown from seed. These are 16 months old-
I grew up collecting oysters off the rocks in coastal New England, and love them! And my home-growns (still searching for a name) were delicious! Having a few more for lunch today!
