Artificial diets for juvenile queen conch
Researchers found juvenile queen conch fed diets containing added macroalgae had higher survival than a control given catfish feed only.

Trial finds biomass harvest of cobia unaffected by stocking density in RAS
The establishment of land-based recirculating systems for cobia could expand production of the species. The authors, who demonstrated cobia are well suited for culture in tanks, conducted a study to compare the performance of cobia reared at different densities.

Trials advance low-salinity culture of cobia, pompano, other species
Collaborative research in Florida is developing technologies for rearing marine fish in low-cost, low-salinity recirculating systems. Spawning and larval production studies have led to the mass production of juveniles.

Food for thought: Feed management strategies, part 2
Production goals may call for specialized diets to meet market or other demands. An evaluation of feed management strategies can optimize culture conditions and maintain efficiency.
Aquafeeds
Food for thought: Feed management strategies, part 1
Based on thorough knowledge of the culture species, feed formulations must deliver protein and energy, and a balance of nutrients in a palatable form consumed with little waste.

Florida study achieves tank spawning of southern flounder
Southern flounder offer potential in aquaculture to answer declining fishery landings and increased demand, but insufficient fingerlings are available.
