Ramamirtham, C P and Dineshbabu, A P (1988) Calcium exchanges between sediments and water in some culture ponds with stress on carbonate and bicarbonate alkalinities. Indian Journal of Fisheries, 35 (1). pp. 37-40.
Tlie results of a short term study of the hydrological parameters like salinity, dissolved oxygen, phosphate, nitrate, nitrite, alkalinity, pH and dissolved calcium in the pond waters and the parameters, like available phosphorus, nitrate and exdiangable calcium for the bottom sediments for three culture ponds at Narakkal are presented and discussed, for the period late pre-monsoon to late post monsoon of the year 1985. From the observe! distribution of the various parameters in the sediment and overlying water, gei^-al conclusions as to the d^ffoe of exchange between sediment and overlying water are drawn. The calcium exchange between soil am overlying water seemed to be maximum during monsoon and that too in ponds where vertical turbulence is of a high degree due to tidal influences. Where the tidal influences are weak, retention of Calcium in the sediments was high and likewise the carbonate alkalinity.
