Abstract: The study was carried out to investigate the soil-water quality and production parameters of 9 selected semi-intensive shrimp ghers in Bagerhat and Khulna districts of Bangladesh over a growing cycle. Physico-chemical parameters of soil-water were measured and analyzed by standard methods. Gross yield (14998.05 kg /ha/cycle) of shrimp was also calculated from the stocking and harvesting data. Most of the parameters of soil and water correlated significantly with each other suggesting a high degree of interactions between different parameters in the system. A pattern of qualitative and qantative difference of zooplankton over phytoplankton was recorded in the semi-intensive farms Therefore, a high degree of salinity fluctuation and iron deposition in waters was also documented. However, significantly lower concentrations of phosphorus in the soil indicated a net retention and trapping of phosphatic nutrients in the environment. After that cropping pattern was two cycles per year, Feeding frequencies was four times in a day and Penaeus monodon production ranged from 4275 to 9645.66 kg /ha/ cycle in semi-intensive farms. The present findings indicate that semi-intensive systems served as less health risk in shrimp production and heavy usage of the surrounding water.
