Suitable soil for Arowana farming is of sandy clay type (clay content 55% – 60%) and water supply throughout the year from natural sources such as hill water, rivers, dams and lakes.
Water quality is as follows:
Temperature 29 – 31 ° C
pH 6.5 – 8.5
Dissolved oxygen 5 ppm
Alkalinity 60 -100 ppm CaCO3
Hardness of 100 ppm
Turbidity 30 cm and
Ammonia 1 ppm
Soil pH affects water quality. Therefore, liming should be done for acidic soils and the quantity of lime required is dependent on the acidity of the soil. Soil fertilization can be done using organic or non-organic fertilizers with a concentration of Nitrogen 0.95 ppm and Phosphorus 0.15 ppm.
