Aquaculture Aeration

Aquaculture Recirculating System for Aquaculture Pond Aeration

Aquaculture Pond Aeration Increases Fish Production And Improves Fish Health And Growth Rate.

Aquaculture pond aeration is vital to the vigorous health and vitality of fish. Without enough oxygen, fish become stressed and their growth rate slows. Additionally, the lack of oxygen at the bottom of the pond will allow the build-up of fish waste and other organic nutrients. As this material decays, it leads to the build-up of toxic gases which are harmful to the fish. Paddlewheels and surface aerators do not address these problems or correct them.

Complete aquaculture pond aeration of the bottom through the use of an aquaculture recirculating system and toxic gas removal enables oxygen breathing microorganisms and insects to feed on organic sediment and organic waste( just as a snail does in an aquarium.) Once oxygen levels are restored using this aquaculture equipment the entire water column and toxic gases at the bottom are removed. Fish then feed on the insects at the bottom.

Turbulence produced by conventional aquaculture equipment re-suspends muck and mixes toxic gases and anoxic water into the water column. The CLEAN-FLO Continuous Laminar Flow Inversion and Oxygenation type aquaculture recirculating system restores and maintains aerobic conditions in water bodies by employing natural non-turbulent inversion through aquaculture pond aeration from bottom to top. Oxygen levels remain consistently high, water quality improves and organic sediment and waste is converted into food for fish, producing rapid fish growth.

Supplementation with Nualgi Lakes will further increase fish health and growth rates.  Nualgi Lakes is formulated to produce accelerated diatom growth which in turn stimulates zooplankton growth – a beneficial food for fish.  Diatoms are the primary food source at the base of the fish food chain.  Grow diatoms, grow fish!  When nutrients go into the fish food chain, they are unavailable to weeds and algaeDiatoms also absorb carbon dioxide and produce oxygen by photosynthesis, all benefits in any aquaculture pond.

AQUACULTURE AERATION SUCCESS STORIES

Examples of our success include:

Tests at Auburn University in Georgia showed that fish production increased from 3,000 lbs. per acre in un-aerated ponds to 6,000 lbs. per acre in aerated ponds by using CLEAN-FLO’s aquaculture recirculating system and aeration equipment.

In seasonal production tests monitored by the Minnesota Department of Natural Resources, Operation Walleye at Alexandria, Minnesota demonstrated an increase in walleye fingerlings from an average of 38.3 lbs. per acre for un-aerated ponds to 69 pounds per acre after CLEAN-FLO’s aquaculture pond aeration. The fingerlings in the un-aerated ponds averaged 4.5 fish per pound, while the fingerlings in the CLEAN-FLO’s aquaculture pond aeration averaged 3.2 fish per pound.

Tests by Minnesota Department of Natural Resources in St. Paul, Minnesota on two CLEAN-FLO’s aquaculture lake aeration showed more abundant fish, which were twice as large as the statewide or local average. A fishing survey showed an average of 49 hours per acre fishing pressure in 13 neighboring un-aerated lakes versus 133 hours per acre for these two CLEAN-FLO aerated lakes. Minnesota Department of Natural Resources (PDF)

Minnesota DNR tests of Mountain Lake in 1988 showed that since an aquaculture equipment was added to Mountain lake in 1983, white crappie population became 77 times the regional average, bluegill 20 times and northern pike 7 times. Minnesota DNR tests of CLEAN-FLO’s aquaculture recirculating system on Crystal Lake at Lake Crystal, Minnesota showed the walleye population at nine times the regional average.

Taiwan fish farmers reported double the growth rate, no more fish kills, and double the number of fish raised using the CLEAN-FLO aquaculture recirculating system and aquaculture equipment.
Tests by a commercial fishery in Alexandria increased the fingerling quantity by a factor of 6.8, with flawless health and quality. In 1987, CEID Fisheries out-produced all 22 DNR fisheries stations in the state of Minnesota. One 12.6 acre rearing pond out-produced the total of 1,107 acres used by the #1 DNR fisheries station.
