Shrimp aquaculture principally Litopenaeus vannamei farming in India is developed into an expectant growth rate for the past decade. The intend of the search was to establish effective changes in water quality parameters in L. vannamei culture ponds. A total of nine water quality parameters such as Temperature, pH, Salinity, Dissolved Oxygen, Alkalinity, Hardness, carbonates, Bi-carbonates, and Ammonia were studied in 20 shrimp culture ponds (9 at Kongodu, 6 at Mogalipalem, and 5 at Gorripudi towns) of East Godavari district, Andhra Pradesh. The temperature was ranged from 26.2 °C to 29.8 °C in all ponds. The pH varied from 7.5 to 8.2. Dissolved oxygen varied from 4.4 to 8.6mg/l. Minimum values of dissolved oxygen were recorded at Gorripudi village ponds and maximum in Mogalipalem. Low salinity (5ppt) was observed in Kongodu ponds and high (8ppt) in Mogalipalem ponds. The minimum (177.7ppm) and maximum (316.8ppm) alkalinity was observed in Kongodu ponds. The hardness ranged from 1305ppm to 2445ppm. The values of ammonia were 0.01 – 0.1mg/l. The present study concluded that shrimp culture water parameters must vary even those ponds aren’t geographically significant extended distance and as well as good water quality parameters supervision in all the vannamei culture ponds help the Better Management practices (BMPs) to produce healthy, good survival, growth, and production. The collective effect of these water parameters studied was in the optimal range for shrimp culture and will replicate the shrimp production.
