Correct Pond Preparation



After every aquaculture cycle, deterioration of the pond bottom is unavoidable. Soil ecology is disrupted. If care is not given to the pond bottom soil, it will no longer be possible to sustain successive and productive cropping. This is the reason why many farms have been experiencing crop failure after a few cycles.

Favorable pond bottom conditions during a prawn culture cycle can be obtained through proper pond preparation. This is done to ensure high survival rates and better harvests. Traditionally, pond preparation requires drying, trenching and scrapping off of black soil or sludge which has accumulated after a cropping. Furthermore, this is followed by tilling and soil sampling to determine soil pH and the amount of lime needed to adjust it. The whole process is dependent on weather conditions and is time consuming and very tedious.


Two major factors that affect growth and survival rates of prawns and fin fishes are:


  •  Soil acidity

  •  The presence of hydrogen sulfide (H2S) build-up


Soil acidity can be corrected by liming. While hydrogen sulfide is oxidized through sun drying of the pond bottom till fissures are formed in order to liberate it into the atmosphere. If these two major factors are not corrected before stocking, the succeeding cropping will cause prawn/finfish growers a lot of problems.


To minimize this, we recommend bioaugmentation through the use of NS Series ER-49, an innovative biotechnological approach.  Bioaugmentation simply means the adding or supplementing of beneficial bacteria to a waste stream to hasten the decomposition of organic wastes and metabolites that has accumulated.


NS Series ER-49, was developed as a solution to the numerous problems related to pond preparation.  NS Series ER-49 is a scientifically blended concentration of specially selected, adapted and cultured bacterial formulation with enzymes and special buffers designed to remove organic wastes and toxic metabolites during pond preparation in aquaculture systems.


Microbial strains and enzymes present in NS Series ER-49 speed up the degradation of organic compounds that has accumulated. It contains specially selected saprophytic bacteria that produce powerful enzymes that breaks. up organic compounds trapped in soils, thus liberating them. Prolong exposure to sunlight in order to accomplish. this will now be shortened, making pond preparation easier, less time consuming and at a lesser cost. NS Series ER-49 also replenishes the soil in pond bottom with the right type of microflora that is needed to sustain a balanced soil ecological system.







Removes H2S, NH3 and CH4


Removal of obnoxious odors


Speeds up the degradation of remaining unstable organic wastes after cropping


Minimizes soil/pond bottom deterioration


Shortens pond preparation time and cost


Replenishes soil microflora


Ensures better harvest for the ensuing cycle






  pH - 6.5 to 8.5


  Free flowing tan powder



Moisture content   


Bulk density   

  0.50 to 0.61 g/cm3

Standard packaging   

  25 kg. metal drums and 1 kg. plastic bottles




Bacteria and enzymes present in NS Series ER-49 perform within a pH range of 3.5 to 9.5 with the optimum near pH 7.5. Bacteria remains 100% efficient in temperature as high as 65 C. However, at 80 C, the efficiency diminishes.






Store in cool dry place. Keep out of direct sunlight. Avoid direct inhalation. Wash hands with warm after handling.
