STUDY ON WATER QUALITY PARAMETERS OF SHRIMP FARMS IN THREE DIFFERENT LOCATIONS IN NELLORE DISTRICT OF COASTAL ANDHRA PRADESH, INDIA

Abstract

The study was conducted to analyze the water quality parameters on 15, 30, 45, 60, 75, 90,105 and 120 days of culture in Pennaeus vannamei shrimp farms in three different locations (L1 : Kavali- Allur; L2: Nellore; L3: Gudur-Kota) of Nellore district shrimp farming areas during four crops (two summers and two winter) C1(Crop-1), C2 (Crop-2), C3 (Crop-3) and C4 (Crop-4) during where shrimp culture is prominent in the Nellore district. The two way ANOVA results show that there are significant differences in water temperature, transparency, Dissolved Oxygen, alkalinity, hardness and total ammonia nitrogen and there is no significance difference for Salinity and pH, hardness at different time intervals of culture. The results are also Significant for transparency, Dissolved oxygen, Salinity, alkalinity, hardness and total ammonia nitrogen and are not significant for temperature and pH among the three locations. Based on the present study, it is concluded that the water quality parameters will vary from location to location within region, during days of culture and also during summer and winter crops.
