Nitrification is a decomposing process of ammonia to nitrite and nitrate. In an aquatic ecosystem, the process acts important role in the nîtrogen cycle. Nitrifying bacteria and phytoplankton as primary producers of inorganic matters, have a unique relationship to the need of ammonia and nitrate.

In an aquatic ecosystem, only nitrifying bacteria produces nitrate which will be consumed by primary products of inorganic matters. In a shrimp ponds ecosystem the heterotrophic organism or bacteria will mineralize organic substance of unconsumed food from over feeding rate, and of shrimp excretion, hence increasing ammonia concentration.

Shrimp ponds are rich in organic substances; and nutrient; due to high stocking density and higher days of culture. It is an ideal place to grow the heterotrophic bacteria. Its decomposition products; ammonia; at certain limit can be harmful to the shrimps, hence causing failure of harvesting.

The role of Bio-Nitor in an aquatic ecosystem is enhancing the complete nitrogen cycle. As a primary producer of inorganio matters, the bacteria can change productivity of the ecosystem from regenerative productivity to a new productivity.

The role of Bio-Nitor in an aquatic ecosystem is to reduce accumulation of ammonia concentration, lf there is no nitrifying bacteria in the ponds, the growth of shrimps would be inhibited at all stages during culture periods at all seasons.

Bio-Nitor enhancing the complete nitrification and denitrification and helps to keep the ponds with healthy ecosystem for intensive shrimp culture.
