Abstract: This study aims at assessing the Physico-chemical properties of water and bottom soil quality in semi-intensive vannamei shrimp farms in Kerala, India. Six different farms were selected from four districts of Kerala based on the stocking density and the technical experience in vannamei shrimp farming, as designated as Farm1, 2, 3, 4, 5 and Farm 6 including triplicates of ponds with a stocking density of 15, 25, 30, 40, 50 and 60/m². The majority of the water quality parameters do not show any significant (p<0.05) differences between farms except dissolved oxygen and temperature recorded in the morning, ammonia and silicate showed a significant difference in winter crop and nitrite showed a considerable difference in the summer crop. Most of the soil quality parameters do not show any significant difference in both seasonal crops except the organic carbon value recorded in the summer season showed highly significant differences. All the parameters were maintained within the optimum level for the vannamei shrimp farming due to the continuous and effective use of good quality water and soil probiotics and minerals and responsible culture management.
