PHYSICO CHEMICAL PARAMETERS OF SOME ABANDONED TIN MINE PONDS IN JOS AND ENVIRONS AND THEIR SUITABILITY FOR FISH FARMING IN PLATEAU STATE, NIGERIA

ranges from 169- 597mg/dm3, total alkalinity ranges from 24.00 - 85.0 mg/dm3, dissolved oxygen ranged from 6.4 - 13.2mg/dm3, BOD ranges from 1.1 - 4.5 mg/dm3, total hardness ranges 98.75 – 298.7 mg/dm3. The study showed that the physicochemical parameters of the ponds are favorable for the survival of Catfish. Control sources of contamination and refuse dumping at pond sites, implement erosion control to reduce ions metal-laden runoff into ponds.ranges from 169- 597mg/dm3, total alkalinity ranges from 24.00 - 85.0 mg/dm3, dissolved oxygen ranged from 6.4 - 13.2mg/dm3, BOD ranges from 1.1 - 4.5 mg/dm3, total hardness ranges 98.75 – 298.7 mg/dm3.
