The Florida Fish and Wildlife Conservation Commission (FWC) is working with Marine Enhancement Center (MEC) network partners to pursue the development of indoor Re-circulating Aquaculture Systems (RAS) for raising marine sportfish to larger sizes before release. Intensive re-circulating systems use an integrated water treatment process that allows most of the water used in aquaculture operations to be reconditioned and recycled. One of the major advantages of RAS technology is a smaller facility footprint that requires less land and can be built away from the coast.
