PHYSICOCHEMICAL PARAMETERS OF EARTHEN FISHPONDS IN THE TEACHING AND RESEARCH FISH FARM YOBE STATE

Because of their importance in fish production, physicochemical characteristics are the most crucial parameters to consider before establishing a fish farm. This study compared the critical level to some significant physicochemical characteristics of earthen fish ponds in the Teaching and Research Fish Farm of the Department of Fisheries Technology, Yobe State College of Agriculture Gujba, Nigeria. Biological oxygen demand, electric conductivity, dissolved oxygen, nitrate, pH, phosphorus, temperature, and turbidity were the variables studied. Water samples from the ponds were collected and tested using established methods and procedures. The findings of this research demonstrate that the parameters measured in the ponds vary. These changes were linked to the ponds' water levels rising on a regular basis. The parameters measured were all within the range of the World Health Organization's worldwide guidelines for unpolluted water bodies (WHO). The findings of this study revealed that pond fish production may be carried out without causing harm to the fish.
