(Brew application) For aquaculture use only
In aquaculture industry, proper preparation of pond is a vital part, in order to get a good crop. Only a well-prepared pond will have good plankton density with adequate food for shrimp/prawn seeds. While preparing the pond for culture, ponds are fertilized with various organic or inorganic fertilizers so that the nutrient content, viz. Nitrogen, Phosphorous, Potassium etc. in the pond may be adjusted to the desired level. It is a known fact that using high dose of fertilizers in the ponds is capital intensive. If the soil quality is not good enough, it will not absorb the nutrients containing in the fertilizers to retain it for a longer period of time. Rather it will be utilised all at a time by the primary producers, which will lead to high algal bloom. This will cause various abnormalities to the pond and will kill the whole culture stock if not controlled at proper time.
In case of unproductive ponds, the primary producers will be starved of nutrients and there will be very few population of fish/prawn/shrimp food organisms in the pond. In order to keep the pond with optimum quantity of food organisms, through out the period of culture, this product has been developed.
Product: It contains 1000 billion CFU per Kg, comprising of 2 species of Bacillus, and two species of Nitrifying microorganisms. The 2 species of Bacillus convert rock phosphate or inorganic phosphates into simple organic phosphates. The organic phosphates exist in the form of mineral acids or organic acids. This is also present in combination with calcium, iron, aluminum, etc. They are insoluble in water and are converted into the soluble phosphates by the activity of these microbes. These microorganisms also produce organic acids like formic acid, acetic acid, succinic acid, etc. in soil. These acids react with rock phosphates and make them soluble in water. Sometimes they release hydroxyl acids, which also convert the rock phosphate into organic soluble phosphates. They reduce the use of phosphate fertilizers.
The nitrifying bacteria convert NH3 derived from various organic decompositions to NO2 and NO3, where NO3 is easily utilized by the phytoplankton as a main source of Nitrogen.
Potassium, which is also a component of phytoplankton production is abundantly available in the water and is generally considered to be not necessary for further supplementation.
DIRECTION OF APPLICATION:
Brew the required amount of the product @ 10 litres of water per Kilogram of product with about 250 grams of jaggery and 50 grams of shrimp or fish pellet feed for about 12 hours and spread on the pond surface after making up the volume to 100 litres with water.
It decreases the dose of fertilisers in the pond.
It creates a healthy environment for the useful microorganisms.
It keeps off pathogenic microorganisms.
It increases nutrient content in the pond.
It gives adequate planktonic population.
Increases growth rate of the culturing stock.
It keeps the culture animals healthy.
Apply 1 kg. / Ha. at the time of pond preparation or 5 days before stocking. Intermittent dose of 500 - 700 g /Ha can be applied as per water quality and transparency.
STORAGE: Store in a cool dry place.
