Walleye have been raised for many years by both private and public sectors, mainly in outdoor pond type systems. New technologies are now being utilized to raise these fish to a much larger size in a shorter time. Indoor larval tank rearing systems have been demonstrated in Iowa for many years and now UWSP-NADF is using heated recycled water systems for grow out.
The method of production is in alignment with consumer expectations: BWF’s indoor Recirculating Aquaculture System (RAS) grows seafood in a clean environment that allows control to a degree not available in open system aquaculture (ponds, net-pens, flow-through). Recirculating systems maximize water re-use through the removal of solids, bio-filtration, gas balancing, oxygenation and disinfection
