The physico-chemical properties of waters from 28 ponds of Thakugaon Sadar Upazilla, Thakurgaon, Bangladesh were analyzed to assess their quality for fish production as well as algal growth and development. The variation in the physico-chemical parameters of the aquaculture ponds above or below standard values has potential effects on the health and productivity of aquaculture. Overall, we found that the pond waters were acidic to neutral (pH varied from 6.0 to 7.2) in nature that is suitable for aquaculture. The dissolved oxygen (DO) concentration was within the safely limits (5 mg O₂ L<SUP>-1</SUP>) for fish production but more DO level should be present for all aquatic life especially for the growth and development of fish. The COD (chemical oxygen demand) of all pond waters were within the permissible limits (4 mg O₂ L<SUP>-1</SUP> by COD<SUB>Mn</SUB>) for fish production. The temperature values were remained within the standard values (20~32℃) in all the aquaculture ponds for warm water fishes. Pond water samples contained Ca<SUP>2+</SUP>, Mg<SUP>2+</SUP> and Na<SUP>+</SUP> as the dominant cations, and HCO₃<SUP>-</SUP> and Cl<SUP>-</SUP> were the dominant anions. All samples were within ‘soft’ class regarding hardness. Based on Cu<SUP>2+</SUP>, Zn<SUP>2+</SUP>, Mn<SUP>2+</SUP> and Fe<SUP>3+</SUP>, all pond water samples were within the ‘safe’ limit for algae production.
