In the current study, a total 90 samples were collected random way from three different fish species (Ttilapia niloticus, Mugil cephalus and Clarias) 30 of each type collected from Kafr El-Sheikh city, Egypt. These samples were subjected for bacteriological examination to evaluate the quality and freshness in farmed fish. The mean value of total bacterial count / g of Tilapia niloticus, Mugil cephalus and Clarias gariepinus were 6.73×10 4 ± 2.03 ×10 4 , 8.33×10 3 ±2.32× 10 3 and 4.1×10 3 ± 7.69×10 2 cfu/g, respectively. The mean values of coliforms count / g were 3.25×10 2 ± 8.04×10, 2.1×10 2 ± 6.74×10 and 1.06×10 2 ± 5.0×10 MPN/g, respectively. The mean values of staphylococcal count /g were 2.44×10 5 ±7.13×10 4 , 8.67×10 3 ±2.23×10 3 and 4.74×10 4 ± 7.48×10 3 cfu/g respectively.

The present study was conducted in farmed fish in Kafr El-Sheikh city Egypt to find out the chemical evaluation of the quality of most famous types of fish in Kafr El-Sheikh city in Egypt to determine the nutritional value of these cultured freshwater fishes. Quality indices were evaluated in 90 samples from three different fish species collected randomly from farms of Kafr El-Sheikh city (Mugil cephalus, tilapia niloticus and Clarias gariepinus) 30 of each were collected from different farms in Kafr El-Shiekh city, Egypt. The results of pH, total volatile nitrogen (TVN), Trimethylamine (TMA), Thiobarbituric acid (TBA) and Histamine '5.
