Abstract: Shrimp aquaculture especially Litopenaeus vannamei farming in India is became promising growth rate for the past decade. Andhra Pradesh costal districts are playing key role in India’s shrimp production. The present study was conducted at L. vannamei cultured ponds, located at various coastal districts of Andhra Pradesh state, India, where shrimp farming was practicing large scale level in semi-intensive culture systems of brackish water aquaculture. The aim of the study was to determine the beneficial role played by the water quality parameters in L. vannamei culture pond. A total of 4 districts Guntur, Krishna, West Godavari and East Godavari were selected out of 13 districts of newly formed Andhra Pradesh state for the present study and a total of 320 vannamei culture farms were selected from all four districts both randomly and purposively and 80 vannamei farms were selected from each district. The study was conducted during the period of February to June 2019 (summer crop) shrimp farms and water samples collected and analysis were carried as per the procedures of APHA^[1]. A total of 10 water quality parameters such as temperature, salinity, pH, total alkalinity, total hardness, calcium hardness, magnesium hardness, total ammonia, nitrites, and dissolved was measured. The results showed that majority L. vannamei farmers were maintaining optimum water quality in their shrimp culture ponds, some parameters had shown slight deviation (Table: 2) compared with the optimal water quality values (Table: 1). As the water quality were maintaining at optimal levels and the discharged water is safe and non-hazardous to the natural environment. The maintenance of optimal water quality parameters could be attributed to the implementation of Better Management Practices (BMP’s). The present study concluded good water quality parameters management in all the vannamei culture farms help the Better Management practices (BMPs) to produce healthy, good survival, growth and production of L. vannamei shrimp by brackish water aquaculture from coastal Andhra Pradesh of India.
