Abstract

Aim: The aim of the study was to assess the important physico-chemical parameters (salinity, temperature, transparency, pH, dissolve oxygen, total hardness, calcium hardness, magnesium hardness, total alkalinity, ammonia, nitrate-N and nitrite-N) in the earthen and PEL culture ponds of Sea Aquafarm, Surat (Gujarat) and to develop the appropriate management strategies correlation were also carried out among the studied parameters.

Materials and Methods: The study the water samples were collected during summer crop(March to June 2021) from earthen and polyethene lined ponds of shrimp farm, Sea Aquafarm, Surat (Gujarat). The water samples were collected in pre-rinsed and tagged wide mouthed polythene bottles and water quality parameters were analysed in-situ and for remaining parameters.

Results: The results showed that salinity (26.250±1.077 ‰), temperature (27.925±0.733 °c), transparency (33.125±9.544 cm), ph (8.125±0.123), dissolve oxygen (6.875±0.334 mg/l), total hardness (4462.500±119.791 mg/l), ch (340.680±22.494 mg/l), mh (881.280±38.705 mg/l), total alkalinity (245.000±11.979 mg/l), ammonia-n (0.267±0.191 mg/l), nitrate-n (9.447±2.605 mg/l) and nitrite-n (0.162±0.062 mg/l) in earthen pond and salinity (25.750±0.819 ‰), temperature (28.900±0.725 °c), transparency (44.750±2.407 cm), ph (7.932±0.124), dissolve oxygen (6.175±0.302 mg/l), total hardness (4650.000±154.110 mg/l), ch (330.660±5.010 mg/l), mh (933.135±36.215 mg/l), total alkalinity (301.250±11.232 mg/l), ammonia-n (0.455±0.218 mg/l), nitrate-n (12.245±2.591 mg/l) and nitrite-n (0.225±0.064 mg/l) in PEL pond.

Conclusion: It was concluded that the water quality parameters in both the ponds were non-significantly different and the similar pattern among these parameters were also quantify by correlation.
