A multi-species evaluation for fish-free aquafeeds
Fish-free aquafeeds trials demonstrate the feasibility of the complete removal of fishmeal and fish oil from the diets of the tested fish species.

Florida permits recirculating red drum farm led by former Kingfish Maine manager
Pine Island Redfish will soon begin producing red drum (Sciaenops ocellatus) in a recirculating aquaculture system (RAS).

Evaluating soybean-based diets for cage-raised red drum
A 15-week feeding trial evaluated the replacement of fishmeal with soybean products in the diet of advanced juvenile red drum.

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.

Fatty acid composition of red drum maintained by fishmeal, fish oil
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.
