ABSTRACT


Physical water quality parameters were conducted to assess raised fish pond waters in South Eastern Kenya University in relation to their potential for catfish culture uses. Water conductivity, TDS, salinity DO and temperature were monitored for a time period of two months in relation to feeding and growth of Clarias gariepinus. The physical water quality parameters results revealed a rising trend behavior thought the study. The result revealed that the physical water quality variables were significantly different (P<0.05) which could be attributed to feed input and exposure to strong heat from the sun in the semi-arid environment.
