Abstract
This study evaluates the impact of seasonal fluctuations and hydrochemical water parameters on the body weight gain of common carp (Cyprinus carpio) in intensive aquaculture. The study was conducted on 1-hectare ponds that had two different stocking levels (5,000 and 7,000 fish/ha). The results show that the growth rates considerably slowed down after mid-summer, and weight gain slowed down to 63.7% in May to 8.6-12.0 in September, which was mainly due to thermal stress and hypoxia. The research scientifically establishes the optimal levels of thresholds to maximize productivity: ammonia ( NH3 ) and dissolved oxygen @ above 5.0 mg/L and water temperatures between 18.6-22.0 C. Moreover, it examines the use of water hardness as a buffering agent against ammonia toxicity.
