Walleye and saugeye growing successfully indoors

Past and ongoing studies at the UWSP Northern Aquaculture Demonstration Facility (UWSP-NADF) have shown that walleye and hybrid walleye can be successfully raised indoors using early advanced spawning, incubation and rearing techniques. Marketing studies indicate good aquaculture potential and high demand.

Biomass density affects bass production

The production period for largemouth bass in ponds hampers the economic feasibility of pond culture in the United States. A study demonstrated that bass fingerlings could be raised at high densities in a semi-closed recirculating system without serious mortality, size variability or growth retardation.

Flow rate estimation for RAS

The water quality in recirculating aquaculture systems is generally a function of the tank size, biomass, feed inputs and waste treatment efficiency. Adequate biofiltration can control the build-up of ammonia-nitrogen and nitrate-nitrogen in the systems.

Recirculation meets aquaponics

Today’s aquaculture industry is rapidly adopting recirculating aquaculture systems (RAS) for hatchery and nursery applications. Recently, there has been a move to combine RAS technology with the floating raft aquaponics.
