摘要：Shrimp aquaculture especially Litopenaeus vannamei farming in India is reporting promising growth rate for the past decade and more than 14 million people were depending on this sector. The present study was conducted at L.vannamei cultured ponds, located at various coastal districts of Andhra Pradesh state, India, where vannamei farming was practicing at commercial level in semi intensive systems of aquaculture. The aim of the study was to establish the beneficiary role played by the water and soil quality parameters in vannamei culture as well as environment. A total of 3 districts were selected out of 13 districts of newly formed Andhra Pradesh state for the present study and a total of 60 vannamei farms were selected both randomly and purposively and 20 vannamei farms were selected from each district. The study was conducted during the period of October to January (second crop of vannamei culture).Water and soil samples were collected from the selected vannamei farms and analysis was carried as per the procedures of APHA. A total of 11 water quality parameters such as color, pH, phosphates, total alkalinity, total hardness, chlorides, TDS, salinity, ammonia, nitrite and nitrate and 6 soil quality parameters such as color, pH, Total Organic Carbon, Nitrogen and Phosphorus were analysed for all 60 vannamei farms. The results showed that majority vannamei farms were maintaining optimal water and soil quality parameters and few of the selected water and soil quality parameters had shown deviation from the optimal values. As the water and soil quality were maintaining at optimal levels and the discharged water is safe and non hazardous and more fertile and in turn beneficial to the environment. The maintenance of optimal water and soil quality parameters could be attributed to the implementation of Better Management Practices (BMPs)on suggested by MPEDA, Govt. of India. The study conclude that the maintenance of optimal water and soil quality parameters in all the vannamei culture systems helps the environmental friendly practices of shrimp aquaculture in India.
