An Assessment on Seasonal Physico-Chemical Variations of Charipunia Beel of Morigaon District, Assam, India
Year: 2025
Type: article
Abstract: The present study was conducted to evaluate the seasonal physicochemical characteristics of Charipunia beel (7.0 ha) in the Morigaon district of Assam over a one-year period from May 2022 to April 2023. The majority of physico-chemical parameters were found to be a favorable range for growth and reproduction within the water temperature of aquatic species ranged from 18.60o C to 29.30o C, water pH from 5.5 to 7.9, dissolved oxygen ranged from 4.5 mg/l to 7.6 mg/l, total alkalinity from 42.3 mg/l to 67.1 mg/l, total hardness from 51.3 mg/l to 70.2 mg/l, free carbon dioxide from 5.5 to 9.3 mg/l, turbidity from 3.1 NTU to 4.6 NTU, and ammonia nitrogen ranged from 0.14 mg/l to 0.32 mg/l. Although the beel conditions were favorable for fish production, there is an urgent need for strict imposition and monitoring of fishery regulations during the banned season. In addition, the identification and protection of feeding and breeding grounds of Indigenous fishes and awareness among fishermen are very much needed for the sustainable use of the beel.
