Abstract
A method for treating and improving the quality of pond water used in growing aquatic species for aquacultural applications by adding to the pond water active bacteria that are preferably grown on site in combination with a nitrification enhancement agent such as calcium carbonate or calcified seaweed, and an optional reaction surface area modifier such as calcified seaweed or plastic or metal particles or fragments.
Claims18
A method for treating water in a growing pond used in an aquaculture application, the method comprising:
- generating a batch of active bacteria solution in a biogenerator around once every 12 to 36 hours over the course of a treatment cycle, wherein the biogenerator is located near the growing pond used in the aquaculture application and wherein the active bacteria are useful for remediating the water by degrading organic waste and inhibiting the growth of pathogenic bacteria;
- adding each batch of active bacteria solution from the biogenerator to the water in the growing pond;
- providing a nitrification enhancement agent comprising an agent that increases the alkalinity of the water, an agent that provides increased surface area for the growth of biofilms, or both;
- adding the nitrification enhancement agent to the water in the growing pond contemporaneously with at least one of the batches of active bacteria;
- and
- wherein the active bacteria is selected from the group consisting of the genera Bacillus, Bacteroides, Bifidobacterium, Lueconostoc, Pediococcus, Enterococcus, Lactobacillus, Megasphaera, Pseudomonas and Propionibacterium.
The method of 6 wherein the nitrification enhancement agent is calcified seaweed that is added to the water in the growing pond at a rate of around 100 lbs. per 1,000,000 ft3 of water.
