To conduct survey on the present status of coastal aquaculture practices in the Cox's Bazar district; to conduct an ecological study on the existing coastal aquaculture practices in the Cox's Bazar district; and survey on the commonly occurring shrimp diseases and their relationship with environmental parameters.
About 220 farms in Cox's Bazar district were selected for data collection with a pre-tested questionnaire. After completion of collection of data, all the data will be compiled and analyzed. Ecological status of the farms were determined from six selected ponds of Matamuhuri, Bakkhali and Naf river basin. Water quality parameters viz., depth, temperature, salinity, pH, transparency, free carbon dioxide, conductivity, alkalinity, dissolved oxygen, inorganic nutrients (ammonia, nitrite, phosphate and silicate) chemical oxygen demand, total nitrogen, total phosphorus and hydrogen sulfide were determined. pH, salinity, alkalinity, nitrogen phosphorus and organic carbon of soil were also studied. Biological parameters viz., phytoplankton, zooplankton, benthos, total heterotrophic bacteria and total coliform were considered for the study.
The information, which was generated through survey will provide a general picture of the existing brackishwater shrimp/ fish culture pattern in the Cox's Bazar district; and the findings highlighted the ecological status viz., quality of water and soil and biological condition of each microcosm and its relationship with disease of the stocked species.
