a=not available; b=water obtained from catfish tank; c,d,e =in the same column with different superscript letters are different (P <0.05); A1 and A2=catfish pond use chicken offal; B1 and B2=catfish pond use commercial fish feed; C1 and C2=tilapia pond use spoiled egg; D1 and D2=tilapia pond use commercial fish feed; Total aerobic and fecal coliform counts in water samples obtained from all sources were not significant different (P>0.05). E Coli was counted less than 3 MPN/gr ( 0.47 log MPN/gr) for all catfish and tilapia samples and less than 3 MPN/mL (0.47 log MPN/L) for all water samples.
