The pond environment is a complex system of inter-linking processes. Maintaining the balance of critical parameters is a fundamental requirement for successful aquaculture.
Intensive aquaculture farming produces large amounts of organic wastes even in a single crop. Much of these organic waste materials accumulate in the pond and cannot be utilized by the phytoplankton through photosynthesis. Oxidation of these organic waste compounds depletes the dissolved oxygen deep in bottom soils of shrimp and fish ponds, resulting in toxic metabolites such as hydrogen sulfide, methane, ammonia, and nitrite which are the key culprits for high mortality rates in aqua farming.
Among the latest attempts at improving water quality in aquaculture is the application of beneficial microorganisms and biodegrading bacteria and/or enzymes to the ponds. This type of biotechnology, known as “bioremediation”, involves the manipulation of micro-organisms in ponds to reduce pathogenic bacteria, enhanced mineralization of organic matter and removal of undesirable waste compounds.
Using its expertise in microbiology, BIOMIN has developed effective bioremediation solutions to improve the pond environment (AquaStar® Pond and AquaStar® PondZyme). The positive microbial action behind this probiotic mixture include the competitive exclusion of pathogenic bacteria, the elimination of toxic materials such as ammonia, nitrite, and hydrogen sulfide, and the degradation of unconsumed feed. Instead of leaving this to the spontaneous primary colonization of the rearing water by bacteria that is accidentally present, the water is pre-emptively colonized by the addition of beneficial bacteria well adapted to prevailing environmental conditions. Water quality and pond environment is improved as these strains work in harmony with the existing biomass, increasing overall efficiency and hastening the elimination of ammonia and nitrites.
