Many of our scientists are trained ecologists and as a result, we monitor parameters such as NH3,NO2,NO3,PO4,DO,pH,salinity, total alkalinity, carbonate alkalinity, dinoflagellates, blue-green algae, transparency, ciliates, copepods, rotifers, Vibrio harveyii, Vibrio parahaemolyticus, Vibrio alginolyticus,V.vulnificus, V.anguillarium three times a week in all our ponds.
As a result, we found that after 1105 measurements over a 60 day period, our average pond effluent had lower nitrate and phosphate levels (0.9ppm and 0.08ppm respectively) than even the World Health Organization Bottled Drinking Water Standards.
At the moment, all our ponds are rehabilitated abandoned ponds that were either former coconut plantations or low biodiversity Nypah swamps. High biodiversity Rhizophora mangroves have not been destroyed in the construction of our existing 400 ponds. Many of these farms are 10-15 years old and using the right ecological principles, these can produce profitable crops on a sustainable basis. This dispels the myth that prawn farming is unsustainable and that farms cannot produce profitable crops after 5 years.
By developing a deep understanding of pond ecology, we have been able to farm prawns using only 4 paddlewheel aerators per 0.5ha pond operating only 9-12 hours a day instead of continuous operation in conventional intensive farms and yet producing 6MT/ha of Tiger Prawns over 50g average body weight. By using less electricity, we help reduce greenhouse gas emissions as local electricity is generated on fossil fuels.
In order to help mitigate mangrove habitat destruction, Global Satria will be voluntarily laying specially designed REEFWALL© Artificial Reefs that will act as nursery habitats for juvenile fishes.
