Survey on aquatic macrophytes and physico-chemical quality of water from Satla Beel of Barishal district, Bangladesh

Preliminary taxonomic survey on aquatic plants of Satla Beel was conducted from May 2021 to August 2021. A complete of thirty aquatic plant species under twenty families was recorded from Satla Beel. Ecological habitats of hydrophyte species showed variations. The Study was conducted to estimate the diversity of aquatic macrophytes and the physico-chemical parameters of water from four different locations in study area. The chosen parameters were water depth, electric conductivity, pH, salinity, total dissolved solid (TDS), phosphate and dissolved oxygen (DO). Water depth fluctuated from 152 cm to 213 cm, conductivities ranged from 0.23 ms/cm to 0.29 ms/cm, pH scale ranged from 6.60 to 7.60, salinity ranged from 132 to 148 ppm and TDS from 349 ppm to 393 ppm. Mean DO and phosphate were recorded as 3.28 mg/L and 762.25 μg/L, respectively.
