Abstract

Water quality management constitute an integral aspect of aquaculture operation. Limnology is the study of physical, chemical and biological factors of any water body, whether it may be freshwater, brackish water or marine water. The water quality is characterized by various physic-chemical parameters. These parameters change widely due to many factors like source of water, type of pollution, seasonal fluctuations, etc. The present investigation was carried out in Six rearing ponds at Government Fish Farm, Amalnala, Bailampur, near Gadchandur in Rajura Tahsil of Chandrapur District of Maharashtra, India during Summer season from March, 2019 to May, 2019 for a period of three months, in order to study its limnology. Its further study was stopped due to some problems created during sampling. Each pond is size of 40x20x5m. During the period of study, various physico-chemical parameters of six ponds were studied. Their range was found as: Depth of ponds was ranged between 1 meter to 1.5 meters. The ambient temperature was between 33 to 41.5 oC and pond water temperature was noted between 28.5 to 36 OC. pH ranged as 7.0 to 8.5, Total dissolved solids was ranged between 116 to174 ppm, Electrical conductivity was ranged as 230 to 346 µS/cm, Dissolved oxygen concentration was between 104 to 352 mg/l, Free carbon dioxide was between 44 to 220 mg/l. Total alkalinity was ranged as 1400 to 2600 mg/l, Total acidity was between 150-450 mg/l and Total hardness was in between 100 to 250 mg/l. Total 11 parameters was studied. From this study, it may be concluded that, the range of physico-chemical characteristics of ponds are within range recommended by FAO for the good fish production. These ponds are suitable for the culture of fishes and prawns. Fish culture includes Indian major carps like Catla, Rohu and Mrigala and Prawn culture include Giant freshwater prawn Macrobrachium rosenbergii.
