SPATIAL DISTRIBUTION AND THE ASSESSMENT OF POND WATER SUITABILITY FOR AQUACULTURE IN THE SONADANGA AND KOTWALI THANAS OF KHULNA CITY CORPORATION

In Bangladesh, aquaculture has become an extensive practice, and over 12% of the population is involved in it. It well-recognized that water quality determines metabolic physiological activities fishes negatively affects fish production. However, both groundwater surface resources many places are affected by various pollutants. This research was conducted to assess suitability pond for Sonadanga Kotwali thanas Khulna City Corporation Area Bangladesh using spatial distribution. For doing this, samples from 23 cultivated ponds those two were collected analyzing basic physical chemical parameters. Results revealed only pH a favorable range (8.03 7.37) aquaculture, but other parameters like electrical conductivity (EC), total suspended solids (TSS), dissolved (TDS), oxygen (DO), calcium (Ca2+), magnesium (Mg2+), hardness (WH), iron (Fe2+ Fe3+), sodium (Na+), chloride (Cl-), bicarbonate (HCO3-), nitrate (NO3-), phosphate (PO43-), sulfate (SO42-) present excessive concentrations. The Pearson correlation among these found be significant. Although, bodies unsuitable farming, thana had more degraded compared thana. recommended local administration should undertake necessary actions improve conserve area.
