Intensive aquaculture operations can lead to water shortages and pollution. Raising 1 ton of shrimp in a farm requires 50-60 thousands of litres of water. When that water is flushed from the ponds into surrounding coastal or river waters in exchange for fresh supplies, its heavy concentrations of fish feces, uneaten food, and other organic debris can lead to oxygen depletion and contribute to harmful algal blooms. The use of My Green EBT2 in aqua culture ponds breaks down the organic matter in the wastewater, raises the dissolved oxygen, and improves the quality of fish/shrimp crops.
