You’ve heard of CSAs, but what about CSFs? Bianca Piccillo and her husband have just launched Brooklyn’s only community supported fishery, which works just like community supported agriculture. With Mermaid’s Garden Sustainable Foods, Brooklynites can buy into the CSF, buying shares of fish and shellfish from Montauk and Cape Cod, and picking up their spoils at various Park Slop/Clinton Hill/Red Hook foodie locations. Prices start at about $99.00 for six 1.25-pound pickups of whatever fishermen bring in that day. “Fishermen let us know what they catch that morning, and it gets to Brooklyn within a day,” Piccillo said.
