Não foi detectado Staphylococcus coagulase positivo em nenhuma amostra de água e peixe. Na contagem de Staphylococcus sp. a água de enxaguadura da pele apresentou números que variam de 1,0 x 102 a 3,3 x 105 UFC.mL-1; no músculo de 1,0 X 102 a 6,7 x 103 UFC.g-1; no trato gastrintestinal de 1,0 x 103 a 2,9 x 105 UFC.g-\ e na água de cultivo de < 20 a 3,3 x 102 UFC.mL-1. O número mais provável (NMP) de coliformes totais na pele variou de 1,5 x 103 a > 1,1 x 104 NMP.100mL-1; no músculo variou de 2,0 x 10 a> 1,1 x 103 NMP.g-1; no trato gastrintestinal variou de 2,6 x 103 a> 1,1 x 104 NMP.g-1; e na água de cultivo variou de 4,2 x 104 a> 2,4 x 105 NMP.100mL-1. Para coliformes termotolerantes a água de enxaguadura da pele variou de < 3,0 x 10 a 1,4 x 103 NMP.IOOmL-1; no músculo variou de < 3 a 6 NMP.g-1; no trato gastrintestinal variou de 1,2 X 103 a 5,1 x 103 NMP.g-1; e na água de cultivo variou de 3,8 x 102 a 2,0 x 104 NMP.100mL-1. Não houve diferença estatística (P>0,05) entre as populações de microrganismos pesquisados na água, pele e trato gastrintestinal o que reflete a relação direta entre a presença dos microrganismos na água e nesses dois locais analisados.

Staphylococcus coagulase positive was not detected in any sample of pond water and fish. In the Staphylococcus sp. counts the surface tis sue ranged from 1,0 x 102 to 3,3 X 105 UFC.mL-1; in the musc1e from 1,0 x 102 to 6,7 x 103 UFC.g-1; in the gastrointestinal tract of fish from 1,0 x 103 to 2,9 X 105 UFC.g-1; and in pond water from < 20 to 3,3 X 102 UFC.mL¬1. The most probable number (NMP) of total coliforms in the surface tissue ranged from 1,5 x 103 to > 1,1 X 104 NMP.100mL-1; in the muscle from 2,0 x 10 to > 1,1 X 103 NMP.g-1; in the gastrointestinal tract offish from de 2,6 x 103 to> 1,1 X 104 NMP.g-1; and in pond water from 4,2 x 104 to > 2,4 X 105 NMP.1 00mL-1 . In thermotolerant coliforms the surface tissue ranged from < 3,0 x 10 to 1,4 X 103 NMP.100mL-1; in the musc1e from < 3 to 6 NMP.g-1; in the gastrointestinal tract of fish from de 1,2 x 103 to 5,1 X 103 NMP.g-1; and in pond water from 3,8 x 102 to 2,0 X 104 NMP.100mL-1. There was no statistical difference (P>0,05) among the studied populations of microorganisms in water, skin and gastrointestinal tract that reflects the relationship between the presence of microorganisms in water and in these two tissues analyzed. Conceming the musc1e there is difference (P<0,05) among the population of microorganisms in water and muscle, in which muscles were always smaller.
