Problems solved by technology
[0002] The traditional breeding mode, especially the high-density farming mode, mostly consumes a large amount of high-protein feed and maintains the production mode at the cost of polluting the pond itself and the nearshore environment. In addition, farmers use a large amount of disinfectants, Antibiotics and other shrimp medicines, the use of these medicines has seriously damaged the ecological environment
In aging ponds, toxic chemicals have been deposited on the bottom of the pond for many years, forming black sludge and producing a large amount of toxic substances, affecting the normal growth and development of prawns

Embodiment Construction
[0009] From 2007 to 2009, we conducted 17 shrimp ponds with an area of nearly 200 mu twice a year. Without any antibiotics, we used bioremediation technology to repair and maintain the sediment and water quality of aging shrimp ponds. Spray microorganisms, growth promoters, co-metabolism substrates, etc. on the water surface, according to the technical route: take sediment—extract indigenous microorganisms—prepare bioaccelerator—biological oxidation of sediment—biological restoration of water body and adjustment of algae phase— Maintain the natural ecological healthy breeding environment. Creating a natural ecological healthy breeding environment and carrying out healthy breeding have all achieved success. The prawns produced have been tested by relevant departments, and the chloramphenicol index has reached the export standard.

The invention discloses an application method of bioremediation technology in aquiculture. The conventional culturing mode, particularly high-density culturing mode maintains the production mode mostly by consuming a large amount of high protein fodder and polluting the pond and the near-shore environment; and in order to prevent and control fish (shrimp) diseases, farmers use a large amount of shrimp medicaments such as disinfectant, antibiotic and the like, and the usage of the medicaments damages the ecological environment seriously. In the aged pond, toxic chemicals are deposited for years at the bottom of the pond to form black sludge and generate a large amount of toxic substances to influence the normal growth of shrimps. The method carries out bioremediation for the pond substrate sludge and the aquiculture water through measures of supplementing micronutrient, promoter and antidote or throwing beneficial microbe in the ecological system of the pond and the like; and the method reduces the content of organic substances in the pond substrate sludge, increases the diversity indexes of algae, stabilizes the algal phase, and increases the dissolved oxygen in water so as to improve the aquiculture capacity of the pond, improve the water quality, lower the cost and improve the culturing yield and quality.
Description
technical field [0001] The invention relates to the field of aquatic product cultivation, which promotes the aerobic decomposition of organic pollutants and strengthens the self-purification function of ponds through bioremediation technology. Background technique [0002] The traditional breeding mode, especially the high-density farming mode, mostly consumes a large amount of high-protein feed and maintains the production mode at the cost of polluting the pond itself and the nearshore environment. In addition, farmers use a large amount of disinfectants, Shrimp drugs such as antibiotics, the use of these drugs have seriously damaged the ecological environment. In aging ponds, toxic chemicals have been deposited on the bottom of the pond for many years, forming black sludge and producing a large amount of toxic substances, affecting the normal growth and development of prawns. Contents of the invention [0003] The present invention performs bioremediation of pond bottom...
