Most of the zooplankton are less than 2 mm in size. This live food is preferable for culture of prawns and fishes for 30 to 40 days till such time that the animals are about 10 gms in size. Later on the pellet feeds can be consumed without wastage and pollution to the pond. The costs of culture under this method can come down substantially by anywhere from 25% to 50%. Cultivating artemia as source of live food may be a good idea to have very fast shrimp growth at very low costs. The details are mentioned below.

Use in Polyculture

Where top feeder fishes are grown in combination with Prawns/Shirmps the zooplankton is eaten by the fishes and the fecal matter of the fishes becomes rich partly digested food for the Prawns.The Prawns grow faster and healthier. The pond bottom remains clean.

Artemia is a crustacean that can live in salinity's from 5 ppt to 300 ppt. It is easily hatched from cysts and becomes adult in about 2 weeks. The adult size is about 10 mm. Artemia is a filter feeder and lives on algae, bacteria and detritus. Each female artemia reproduces about 300 live nauplii once in 4 days. Artemia cysts are available in all aqua shops.

Using light and aeration, artemia cysts can be hatched in 24 hours in a 200-liter barrel of seawater and added to the pond. 100 g of hatched artemia cysts can develop into 50 kg of adult artemia in 2 weeks. The diatoms developed using ' NUALGI ' are rich in HUFA (Highly unsaturated fatty acid) and hence the nutritional profile of the artemia will be excellent and it will boost the growth of the shrimps.

Artemia culture can be started in the same pond before stocking the shrimp fry so that live food is readily available as the shrimp grows. In the alternative a separate artemia culture pond may be kept and adult artemia harvested and added to the shrimp pond. As long as the live food is there in the pond the artificial foods may be avoided. After that the shrimps would have grown in size and will now accept artificial foods and grow fast. Further the pollution in the pond will be significantly reduced and animals will be extremely healthy. The cost of feeding will also come down substantially (In excess of 50%). In a one-hectare pond, 100g to 500g of artemia cysts may be hatched and added. Further multiplication will happen automaticall.

For treating sewage, polluted and effluent waters by growing diatoms and reducing COD and BOD and COLOUR.

If 'Nualgi' is applied to effluent waters containing sewage and industrial wastewater (provided there are no toxic chemicals and metals), diatom algae can be made to grow and absorb carbon load and release oxygen. If we have the nutrient analysis of the wastewater we can tailor make the product to suit individual requirements. The release of oxygen and absorption of the nutrient load will reduce the BOD,COD,COLOUR and ODOUR. In some cases the growing algae could remove the color in the water. This can be proved only by trials.

For reclaiming and bringing life to lakes, rivers, and water bodies that are polluted by sewage and other pollutants and those in a state of eutrophication.

Most of the lakes and rivers of the world are severely polluted by sewage and industrial effluents. Due to this there is very little aquatic life and most are in various stages of eutrophication. The heavy load on nutrients like nitrogen and phosphate and the lack of essential trace nutrients for diatom algal growth are the main reasons for such a state of affairs. If ' NUALGI ' is added to the system the diatom algae starts growing changes anaerobic conditions to aerobic conditions.Stops generation of bad ODOUR in the form of H₂S,very soon the water conditions improve. More oxygen and live food returns to the water and very soon the water body is restored to its normalcy. The dosage depends of the nutrient load in the system. As a thumb rule, about 1 kg. of ' NUALGI ' per day is enough for about 4000m 3 of water. Dosage may be reduced or increased depending on actual conditions. After recovery of the water body even a tenth of the above dosage could be enough.

For preventing wild growth of waterweeds, water hyacinth, green algae and blue green algae and other waste plants in lakes, rivers,ponds and other water bodies.

The addition of ' NUALGI ' always removes excess nutrient loads of Nitrogen and Phosphate from the water body by growing diatoms and converting to live food. In the absence of the nutrient load, other exogenous weeds and plants cannot grow. Further in lakes where the wild plants have already grown, if ' NUALGI ' is dosed into it, the rapid growth of diatoms consumes the nutrient chain required for the weeds to grow. Slowly they turn into yellow color and die. Within a few months they disappear from the pond. It is important that systematic dosing of the body of water with ' NUALGI ' should be carried out.

Avoiding mass fish kill.

Oxygen depletion in water bodies is the major reason for mass fish kill . Sometimes toxins released by algal species like blue green algae and dynoflagellates are also responsible for mass fish mortalities. Using 'Nualgi' can prevent this. Addition of 'NUALGI' produces blooms of diatom algae that help crash out green,blue green and toxic algal species from the water body. The blooming diatoms produce very large quantities of oxygen by photosynthesis and is soon converted into zooplankton that is live food for fishes.The water body becomes clean and healthy.

Removing and crashing out of Blue green algae.

Blue green algae proliferate in water bodies that have a source of pollution or excess nutrients washed down from agricultural lands.Some species like anaebana produce neuro toxins.In lakes which supply drinking water to towns and cities the growth of Blue green algae is a big nuisance. By using 'Nualgi' the Blue green algae will crash out of the system and float in the water in the form of fibres or like a green paint.This has to be physically removed.The potability of the water is not affected and the fishes are not harmed. The water is purified and it is safe for normal use.
