Aquaponic system produces red drum, saltwater vegetable species

A project in Florida is studying the feasibility of a marine aquaponic system containing red drum and two native saltwater species. Water that exits the plant raceways is filtered and recirculated to the fish tanks. In tests, sea purslane grew rapidly, while saltwort took almost four months to adapt. The fish exhibited high survival and achieved a feed-conversion ratio of 1.2.
