Soilless flood and drain beds, optimized with colonies of microorganisms improves efficiencies of recirculating aquaculture systems.
The approach developed at Bioponica improves waste uptake by creating a biologically diverse media environment with abundant rhizomal bacteria, nitrifiers and mycorhizomal fungi. The magic in this method is nature at its best.
Sustainable aquaculture is best achieved when viable fish growth has a minimal ecological impact. Recirculating aquaculture systems come close to this, though there is still a significant degree of waste discharged and consequently water lost unnecessarily.
The Biogarden system and the Bioponica process improves the ecological impact by introducing a controlled, food producing wetland with full biological function. This makes it possible for a fish farm to recirculate a greater percentage of its water, rather than discharge the precious water into the environment along with ecologically eutrophic fish waste effluent.
The result is a healthier fish, cleaner environment and additional organic vegetable. If growing produce is not feasible, certainly there is benefit in raising a fresh duckweed fish feed.
Questions and Answers
What is the Bioponica approach to sustainable fish feeding?
Because our method does not require raising fish for the purpose of fertilizing plants, as with aquaponics, we don't feed and farm fish the same intensive manner.
Crowding in ratios of 1lb of fish to 2 or 3 gallons of water is stressful to the fish. Stressed fish are susceptible to disease.
Studies have shown that the Omega 3 fatty acid levels ar elower and they are likely to suffer other physical deficiencies.
Our approach is to raise fish with grasses, decomposing biomass, semi aquatic organisms that lay eggs in the water, algae and microorganisms. In other words, create a pond like environment that supplies all needs. Typically , Western aquaculture methods fertilize ponds with petrochemicals and chicken waste or else feed with cheap manufactured feeds. Bioponics is more consitent with an Asian pond management methods to create organic fertility in water with green biomass. This leads to a pond culture with a natural balance of microorganisms, decomposing grasses and algae that provides a natural and sustainable diet.
Does Bioponica have a problem with feeding fish more common manufactured fish feeds from fish parts, chicken parts and grains?
Yes, for one reason feeding fish with fish is not sustainable. Nor is the energy or carbon cost of processing, packaging and shipping fish feed to all parts of the world. Because fish derived meal often contains PCBs and grain derived feeds are GMO we stay away from conventional options. Besides, grains and fish meal are not the natural diets of filter feeders and herbivores.
Is it possible to fish food that is derived on-site instead of manufactured?
Duckweed is our preferred feed, but there may not generally enough to feed a large amount of fish unless you dedicate space to grow duckweed in the Bio-Incubator.
Another natural pond-like approach we take is to build a food web as a more balanced blend, starting with grasses, weeds and leaves that fish desire. We're talking about filter feeders and herbivores. Carnivores and some ominivores require more animal protein, supposedly. Filter feeders, including tilapia and crustaceans consume the grasses plus they graze on the organisms of bacteria, protozoans and autotrophs that feed on the grasses or the nutrients released from the grasses.
What preparation do grasses require to be utilized as primary fish feed?
We've had success with grasses using various techniques. Silage, freezing, pelletizing and macerating of grasses and weeds will release nutrients and detritus along with a plethora of edible microorganisms. Our Fertili-Feed leaches nutrients and small particles of decomposing grasses which have been decomposed as if through a small silo in the screened feeding bag.
