درست العوالق الحيوانية القشرية- متفرعات القرون و مجذافيات الأرجل- كأحد أهم مكونات النظام البيئي المائي العذب، في خمسة برك من مزرعة السن لتربية الأسماك في بانياس. جمعت العينات خلال الفترة الزمنية الواقعة من بداية شهر تشرين الثاني 2013 م و حتى أذار 2015 م و بمعدل اعتيان واحد شهرياً.
Crustacean Zooplankton Was Studied In Five ponds In AL- Sinn's Fish farm. As a one Of The Most Important components Fresh Water Ecosystem . The samples of zooplankton were collected During Period From November 2013 To March 2015, By One Sampling a Month.

This paper Introduces a clear idea about marine and coastal
biodiversity of crustacean zooplankton and its quantitative and
qualitative monthly variations and its relationship with the changes
of some of the main environmental factors such as temperature,
salinity,dissolved oxygen, transparency and pH.
The study included 132 Free – living fish in Lake of 16 Tishreen Dam,
collected randomly during the period from 22/11/2011 until 22/10/2012, on
average once a month, for detecting the infection of parasitic copepoda, and
determine the distribution rate, and their effect on the fish productivity.
The study included 144 Free – living fish from the Lake of 16 Tishreen Dam, collected randomly during the period from 12/2011 until 11/2012, on monthly basis to detect the infection with Epistylis sp. and determine its distribution rate.
Fish sam
ples were: Cyprinus carpio L., Varicorhinus damascinus, Garra rufus, Tilapia zilli, and Liza abu. Tilapia zilli was the most prevalent in the lake of 16 Tishreen Dam.
The study revealed fish infection with Epistylis sp. on free – living fish in the Lake, with a total infection rate 22.22 % , mainly on Tilapia zillii (29.70 %) and then on mullet (2%);No infection with Epistylis sp. Was recorded on the other fish species. The infection with this ecto Epistylis sp. was recorded for the first time in Syria in our study.
The infection with Epistylis sp. was located on the skin, fins and gills. The highest infection rate was on the fins ( 42.34 %) , followed by skin (37.46 %) , and then by gills (1.87 %) .
The infection with Epistylis sp. had the highest rate in summer ; i.e. during high temperature , low concentration of dissolved oxygen , and slightly high value of BOD.
The study showed that, the water of 16 Tishreen Dam is relatively clean.
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.
Research on marine fish parasites is very low in Syria, and there is
no research on parasites of cultured marine fish. Study was
performed in aiming to detect the occurrence of ectoparasites
worms of siganus rivulatu s Fish.
