Effects of water quality parameters on growth performance of intensive shrimp pond (Litopenaeus vannamei)

Currently, to monitor water quality, farmers in Vietnam need to analyze various indicators which increase production costs. In addition, the limitation of analytical facilities and techniques is a challenge. The objective of this experiment was to evaluate the influence of water quality parameters on shrimp growth rates and the seasonal fluctuation in water quality. A total of 4 modules were randomly selected and analyzed daily for 8 critical parameters during rainy and dry seasons. The SPSS ver.26 was used to evaluate the correlation between multi-parameters and their impact on the performance of shrimp ponds. The results showed that shrimp growth was influenced by salinity, nitrite (NO2-), alkalinity and pH about 80.4%, 75.6%, 67.8%, and 55.7%, respectively. Moreover, water quality fluctuated more during the rainy season than during the dry season. Some parameters that exhibited high fluctuation in ponds were dissolved oxygen (DO) and nitrite.
