.r.ethink aquaculture One mans waste is anothers goldmine. A few little beauties help convert this wealth in my systems, two of them are found here; Lacuna lemnae (duckweed) and aquatic snail. Duckweed at 35% protein is a great nutrient sink and water purifier, but also feeds the fish. Snails clean algae (which reduces oxygen) from tanks housing fish. #aquaculture #betteraquaculture #healthyfish #nosuchthingaswaste #aquaponics #fish #koi #trout #tilapia #fishtanks #duckweed #snails #letthemeatalgae #ecosystems #modifiedecomachine #waterremediation #swimfishy #happyfishy https://www.facebook.com/RAWrTransformations
