تعد البحوث المتعلقة بطفيليات الأسماك البحرية في سورية قليلة، و أما الخاصة بالأسماك البحرية المستزرعة فمعدومة. أجريت الدراسة بهدف التقصي عن الإصابة بالطفيليات الخارجية للنوع السمكي Siganus rivulatus المستزرع و تحديد معدل انتشارها.
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.

The study was performed to discover parasitic Nematoda in
digestive system of Siganus rivulatus (Forsskal and Niebuhr, 1775) in
beach water of Lattakia, and investigation the role of some ecological
parameters on its distribution.
In the present study,a total of 50 individuals ofsurmulletMullussurmuletuswere
examined forexoparasites infections. The specimens were collected from the Syrian marine
waters (Latakia, Jablah) between 15/10/2014 and 30/10/2015. The skin, mouth cavi
ty,
nostrils and gills of each specimen were examined.
One parasite species belonging to Monogenea,Grubea cochlear was identified for the
first time in the Syrian marine waters and in Mediterranean Sea. This species, memberof
the family Mazocraeidae,was isolated from the gills.
The number of infected fish was 20 fish out of 50 sampled fish; withprevalence of
40% and Intensity of 5 parasite/ Fish.
تعد الثروة السمكية إحدى المكونات الحية للبيئة المائية ( البحرية والعذبة ) كما تعد أهم مصادر الغذاء الطبيعية للإنسان إذ تحتوي الأسماك على بروتين مفيد جداً خصوصاً في مجال مكافحة سوء التغذية لاسيما في مرحلة الطفولة
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.
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.
