Tag red drum

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. 

Recent research by the authors evaluated strategies to reduce fishmeal and fish oil in diets for red drum by substituting terrestrial proteins and lipids while maintaining beneficial fatty acids with DHA supplements derived from marine algae.
