Abstract

This investigation was carried out on changes in sediment chemistry of Pangasius ponds under existing farming practices in Mymensingh district. The studies were conducted at 15 Pangasius ponds on a number of sediment chemistry, over a period of three months from July to August. Sediment chemistry parameters i.e. pH, organic carbon, organic matter, total nitrogen and available phosphorus were analyzed within this period. Sediment chemistry of pond varied with pond age and sediment frequency of removal. It was found that pH value of sediments ranged from 5.92 to 6.76 whereas the concentration of organic carbon fluctuated from 0.86 to 2.52%. Organic matter varied from 1.48 to 3.75%, for total nitrogen concentration from 0.08 to 0.19%, and for phosphorus concentration from 17.58 to 82.9%.Inferentially, apart from phosphorus, others sediment chemistry varied significantly (p<0.01) with pond age and frequency of sediment removal. But significant variation was observed in phosphorus only with frequency of sediment removal. Phosphorus value was greater in new pond indicating that primary productivity might be higher. It is concluded that sediment chemistry varied with pond age and sediment removal having wider impacts on primary productivity, pond managementas well as fish production.
