Application of calcium peroxide in Aquaculture


When dissolved in water, calcium peroxide breaks down into calcium hydroxide, oxygen and water. This characteristic gives calcium peroxide a function as the conditioner of water quality which provides a comfortable environment for aquatic life breeding like fishes, shrimps and crabs. The benefits for application of calcium peroxide in aquaculture embody in following aspects.

-providing sufficient dissolved oxygen; This is typically useful for increase the unit production by enhance the breeding density at a limited area, and solve the problem of oxygen-lacking in some seasons especially winter. Unlike other oxygen release chemicals that release oxygen rapidly, calcium peroxide provides a stable and continued source of oxygen thus it is considered an economical oxygen source for extensive aquacultural applications.

-adjusting pH value; Calcium peroxide is approved to be efficient in improving the subaqueous pH value and prevent water from acidification.

-reducing the subaqueous content of ammonium and nitrogen; Ammonium and nitrogen are major factor that prevents fishes from developing, by disseminating calcium peroxide into water, the ammonium and subaqueous content can be remarkably reduced.

-eliminating carbon dioxide and sulfureted hydrogen; in a pond covered with a ice cap, carbon dioxide usually exists in a big quantity and hinders the oxygen absorption of fishes, calcium peroxide also show a great effect on elimination carbon dioxide. Calcium peroxide can remove sulfureted hydrogen during its oxygen release process, this improve the water quality at the lower part.

-preventing anaerobe from proliferation and killing nosogenetic bacteria, defecating aqueous body; Calcium peroxide is an oxidizer than acts as a disinfectant which may efficiently kill ananerobe and nosogenetic bacteria. Calcium peroxide may facilitate depositing floccules and clearing turbid water thus improves the photosynthesis of natant foliage to increase dissolved oxygen.
