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

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.
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.
This work was designed to investigate the effect of temperature of frozen storage and
its duration on some chemical properties (Protein, Ash, Moisture,Lipid) of fishes Rabbit
fish (Siganus rivulatus). The fishes were subjected (from one weak to 150 day) of frozen
storage at two different degrees of low temperatures (-18 C,-24 C).
This study was carried out on /516/ fish individuals of Chub Mackerel Scomber
japonicus (Houttuyn, 1782), which were caught from the Coastal water of Latakia
province (Levantine basin) from December 2014 to November 2015, to identify the
evolution
stages of sexual maturity (by morphological and histological methods)
and determine the spawning period of this important economic species. The results
showed that Scomber japonicus begin with sexual maturity from the beginning of
February and extend until mid-May, with a single peak in Mars. The average value
of the gonado-somatic index (GSI) was (12.46 ± 1.52)% for males and (13.21 ± 3.9)% for
female in Mars. And the total body length at sexual maturity was (21.5) cm for
males, and was (23.5) cm for females. The development stages and gonad maturation
in this specie, are similar with regard to the tissue and the form of gonads and
according to the six gonad maturation steps.
This study was carried out in cooperation between the Faculty of
Agriculture, Damascus University and the General Commission for Scientific
Agricultural Research (GCSAR) in Karahta station of field crops researches
during two growing seasons (2003
-04 & 2004-05).
Four local improved barley lines and cultivars (female parents) were
crossed with five exotic lines and cultivars (male parents) using line × tester
method. The crosses were grown along with their parents in a randomized
complete block design (RCBD) with three replications to estimate general
combining ability (GCA), specific combining ability(SCA) and both mid and
high parent heterosis for number of spikes per plant, number of grains per
spike, thousand kernel weight, and grain yield per plant.
