Five Species of the most widely consumed fish in the Syrian Coast (namely
Merluccius merluccius, Diplodus sargus, Siganus luridus, Lithognathus mormyrus, and
Chelon labrosus). were selected for this research. Samples were collected from the fish
m
arket in lattakia, with weight ranging between 150 and 200g. Samples were cleaned by
removing scales and inner organs, freezed at -35°C for five hours and then stored at -
18°C for a maximum period of six months.
Chemical analysis of fish samples was carried out before and after freezing periods
of one week, 1, 2, 4 and 6 months. Analysis included determination of moisture, proteins,
lipids, acidity, volatile nitrogen, and peroxide value. Organoleptic evaluation was also
performed on the control (fresh samples) and on the frozen samples after thawing and
frying. The evaluation included taste, flavor, color, texture or meat consistency and form
homogeneity.
A total of 30 water samples and 45 infected fish (carp, Cyprinus carpio) were
collected from freshwater fish farm (Dam of 16 Tishreen-Lattakia) and
analysed bacteriological. Macroscopic examinations of infected fish had showed
the presence of haem
orrhagic skin lesions with brown or red spots throughout
their skin. A total of 64 Aeromonas strains were isolated. The Aeromonas
isolates were distributed as follows: Aeromonas hydrophila (34, 53%), A. caviae
(16, 25%), A. sobria (9, 14%) and (5, 8%) of unidentified aeromonads.
Collectively, Aeromonas spp. are considered as opportunistic causative agents
of human gastroenteritis and other infections. Antibiotic susceptibility tests
were carried on all strains of isolated Aeromonas spp. using twenty different
antibiotics by agar disk diffusion method.
The Akaike information criterion (AIC) is a measure of the relative
quality of statistical models for a given set of data.
The Schwarz
Criterion (SC) is a measure to help in the selection between
candidate models.
