Some studies of water quality parameters in private Fish farms, Muzafargarh, Pakistan

Abstract

This study was carried out to investigate present status of various physio-chemical parameters of private fish farms located in village Jalalabad of district Muzaffargarh, Pakistan. Water sampling was carried out on fortnightly basis for winter and summer season. Main physico-chemical parameters like air and water temperature ranged from 24 °C-38 °C and 22 °C–33 °C. While pH ranged from 6.8-8.5.Total dissolved oxygen was found to be 5.93-11.03mg/l. Light penetration varied from 5²- 21.07². The Carbonates and bicarbonates fluctuated within a limit of 22.2-47.2mg/l and 71.04-158.36mg/L. Free carbon dioxide remained very low throughout the experiment. Total dissolved solids varied from 1333-1533mg/L, while alkalinity was found to be 100.64-193.88mg/. Hardness, Calcium and Chloride ranged between 1391.67-1716.67mg/L, 353.33–560mg/L and 7.36-23.68mg/L respectively. The findings of the current study revealed that physico-chemical parameters of water were within permissible range except TD Sand Hardness. It is concluded that water can be useful for fish culture. Correlation coefficient showed positive and negative relationship.
