Abstract
The present investigation was designed to study the bacteriological
quality of 100 samples comprised four species of marine water fish
namely (Sardine, Mullus spp. (Morgan), Pargus spp. (Barbone) and
Chrysophyres (Dinisj) (25 of each) which were collected from
commercial fish markets in Alexandria governorate over a period of 6
months.
So, this study was designed to throw a light on the hygienic quality
of four common marine fishes sold in these markets.
Regarding to the microbiological status ofthe examined fishes,(
Sardine, Mullus spp., Pargus spp. and Chrysophyres) the mean Total
Bacterial counts values were 3.95 x 106 + 1.26 X 106,3.67 X 106+ 0.798

,respectively,
The incidences of different organisms in the examined fish species
namely, Sardine, Mullus spp., Pargus spp. and Chrysophyres for total
Enterobacteriaceae were 84, 92,100 and 92 % respectively, for total
coliforms 72, 92, 100 and 92 % respectively, for total Enterococci 84,
100, 100 and 100 % respectively and for total Staphylococci 92, 100, 100
and 100 % respectively for the aforementioned fish species.
Correlation between the microbiological load and fish species
results in non statistically significant differences in the mean total
bacterial counts and total Staphylococci counts between the four
aforementioned examined fish species.
While, there are correlation between the microbiological load and
fish species results in statistically significant differences in the mean total
Enterobacteriaceae counts between Sardine species (in one arm) and
Mullus spp. and Pargus spp. (in the other arm).
Also, Correlation between the microbiological load and fish
species results in there was no statistical significant difference between
the mean of total coliforms counts of Sardine and Chrysophyres, and also
there is no statistical signific.t difference between the mean of total
coliforms counts of Mull us W., Pargus spp. and Chrysophyres. But,
there was a statistical signifiMnt difference between the mean of total
coliforms counts of Sardine (in one arm) and both Mullus spp. and Pargus
spp. (in other arm).
And, Correlation bet IIm the microbiological load and fish species
results in there was no statillkal significant difference of means
Enterococci counts value between Sardine and Pargus spp. but it was
present between Sardine (in one arm) and both Mullus spp. and
Chrysophyres (in the other arm) . Also, there were no statistical
significant difference of means Enterococci counts values between
Mullus spp., Pargus spp., and Chrysophyres.
Regarding to the mycological evaluation of the examined fishes
revealed that the mean total mould counts values of,( Sardine, Mullus
spp., Pargus spp. and Chrysophyres) were 3.42 + 0.596 x 102, 3.25 +

0.63 x 102 and 5.61 + 1.57 x 102 CFU/g ,respectively.
