Water Quality Management of Diamond Aqua Farm, Mallipattinam, Thanjavur District, Tamil Nadu, India

The present study reported the water quality parameters in relation to growth of tiger shrimp, Penaeus monodon in culture pond at Diamond Aqua Farm, Mallipattinam, Thanjavur District for the period of 135 days from the introduction of fingerlings (10.04.2014) to the harvest day (22.08.2014).The results clearly indicate that almost all the physicochemical parameters like water temperature, pH, carbon dioxide, salinity, total hardness, calcium, magnesium, phosphate, ammonia and nitrite’s average values were increased gradually from the month of April 2014 to August 2014 and remaining parameters like turbidity and dissolved oxygen were increased in the month of April 2014 to August 2014 in the cultured pond. However, they are within the normal range. The variations in the water quality parameters are due to seasonal changes, water exchange and shrimp culture.The growth of the shrimps was assessed from both length and weight parameters. The average length of the shrimp was gradually increased in culture ponds. The minimum and maximum lengths of the shrimp were 2.5 cm were observed in April 2014 and 14.9 cm in August 2014 in the culture pond. The weight of the shrimp was also gradually increased in culture pond from to August 2014. Based on the present investigation, it is concluded that to get the proper growth P. monodon and profit, proper water quality management and feed management is essential.
