Abstract


This research aimed to calculate the number of phsycotrophic bacteria of nile tilapia reared in increased water temperature. For this purpose, 12 nile tilapias with body weight of 35-40 g were randomly allotted into 2 treatments groups with 3 replications. Fish in group 1 (P1) was reared in normal temperature (29±1° C) and group II (P2) was reared in high water temperature (35±1 C). All fish were fed commercial diet 3 times a day for 21 consecutive days. T-test analysis revealed a significant decrease in number of psychotropic bacteria (P<0.01) in group P2. Total plate count (TPC) resulted in fish gills, intestinal, and muscle were 1.5×10³, 7.7x10³, and 9.7x10³ cfu/g respectively. In conclusion, increasing of water temperature reduce the number of phsycotrophic bacteria of nile tilapia.
