Alkalinity, salinity, hardness and total suspended solids (TSS) in water and organic carbon (OC) content, salinity and cations like sodium and calcium in soils were studied from certain shrimp farming areas along Sirkhazhi, Myladuthurai and Nagapattinam taluh of Tamil Nadu and Karaikal of Pondicherry during September 1995. The culture ponds registered higher levels of total suspended solids (133 mgh), salinity (32 ppt) and hardness (6571 mgil) in water and cation content (4166 ppm Na ' ; 2411 ppm ca'++ and salinity (6.77 ppt) in soil samples. The levels of all these parameters were compared with the adjoining no,nculture sites. The variations in the properties of water and soil samples of stocked and non-stocked farms were also studied. The results were analysed statistically to understand any possible inter-relationship between water and soil within the pond as well as among the ponds, their inlets and outlets
