Abstract
Indian major carp culture in India over the years has shifted from semi-intensive and intensive farming. The increase use of additional inputs in the pond has resulted in the huge change in pond ecosystem. The present study was carried out with the objective to find out the variation in the water quality parameters influenced by the high stocking of the carps. It was observed in the study that the various parameters measured were present in high concentrations. At times the values exceeded the regulatory limits for aquaculture pond water. Among the three nitrogenous parameters monitored, the maximum values for nitrate (NO3-) and total ammonia nitrogen (TAN) were observed to be 0.57 mg/l and 0.89 mg/l, respectively, well below the prescribed respective limits of 1 mg/l and 3mg/l for warm water fishes. However, the values of nitrite (NO2-) spiked to 0.15 mg/l and dissolved oxygen levels fell to a low of 3.15 mg/l, impacting the growth of the carps.
