A WAREHOUSE ON LIBERTY STREET in Newburgh is an unlikely site for a shrimp farm. ECO Shrimp Garden, opened in August, offers Hudson Valley—grown shrimp. The Brazilian-born Jean Claude Frajmund seeks to minimize the ecological impact of traditional shrimp-raising and importing methods. Just one of 24 such farms in the U.S., Frajmund employs a closed-water system of 16 saltwater tanks. Open daily (the shrimp sells for $25 per pound); he’ll ship the crustaceans as well.
