يهدف هذا العمل إلى دراسة تأثير درجة حرارة التخزين بالتجميد و مدته على بعض المكوّنات الأساسية/ بروتين، رماد، رطوبة، دهون/لأسماك الغريبة (Siganus rivulatus)، حيث خضعت الأسماك إلى التجميد على درجات حرارة منخفضة /-18،- 24مْ/، و لفترات زمنية مختلفة من التخزين/ من الأسبوع حتى خمسة أشهر/.
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).

The aim of this study is to highlight the potential use of marine algae as well as polypropylene for the removal of crude oil from surface seawater.
The determination of optimal sorption time and sorption capacity of the materials in oil/water bath
and oil bath without water in presence of three oils of different viscosity were investigated. The capacity of oil removal from seawater was related to structure and surface properties as well as oil amount and oil properties especially, its viscosity.
The results revealed that the extension of absorption time does not influence absorption capacity of the examined sorbents in presence of both oils of low and middle viscosity (LV and MV). Nevertheless, the sorption capacity was increased by extending the absorption time to 30 min. For high viscose oil (HV). The sorption capabilities of Enteromorpha exceeded those observed for all of the other algae, while polypropylene fiber showed the highest capacity. Overall, the sorption capacity of the studied sorbents increased with increasing oil viscosity. The absorption capacities of studied materials in the oil bath and oil/water bath were comparable.
The results suggested that substitution of synthetic oil sorbents used in Syria by marine algae is possible in oil removal, which have relatively high sorption capacity.
In This study it has been uses a network for monitoring the pollution with organochlorine pesticides in There marine stations at Lattakia coast: Fishing port, AfamiaCoast, High Institute Of Marine Research Coastusing Cages contained species of musse
lswitch are filter feeders Brachidontes varibilis. Samples had been collected from Lattakia coast.
The results showed a great efficiency of the made network for monitoring the organic pollution in marine environment. It has been recorded a concentration of DDTs is accumulated lower than 2ng/g , Endosulfane and HCB is lower than 1 ng/g too. The results showed that the HCH compounds is dominant in all stations.organochlorine pesticides is accumulated mostly in the biota of station Fishing port, Afamia Coast
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.
We screening for antimicrobial substances production from marine algae of
Syria. We presented results of ١٦ algal species tested by their lipide and
aqueous extracts agaimst Gram’s negative and positive bacteria, as well as one
fungous species.
T
he lipide not aqueous extracts were the active against Gram’s positive
bacteria especially.
No effect founded on the fongous species. In addition we make comparative
viewing with other studies on other mediterranean contries regarding the same
species of algae tested.
Seasonal changes effect on yield and quality of carrageenan from the Syrian
marine alga Hypnea musciformis were studied during 1 year. The carrageenan
yield varied from 31 to 46%. The maximum yield was recorded between April
and September, while l
ow carrageenant content was recorded in December.
The gel strength of carrageenan was maximum in September (260 g/cm²) and
minimum in March (90 g/cm²). The viscosity ranged from 22 to 44cP with a
peak recorded in September. Seasonal variations were not observed in the
gelling (42-50 C°) and melting (60-70 C°) temperatures of carrageenan. The
results indicate that Hypnea musciformis can be considered a good sources for
production of commercial carrageenan in future.
