First record of Grubea cochlear (Monogenea: Mazocraeidae) from (Mullussurmuletus L.) in Syrian marine waters and Mediterranean Sea

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 cavity, 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.

Contribution to the Study of the qualitative composition and biology of Puffer Fishes (Tetraodontidae) in the marine water of Lattakia

This research was carried out during the period 08/28/2012 - 07/29/2013 in order to determine the qualitative composition of Puffer Fishes (Tetraodontidae) in the marine water of Latakia. Fish samples were collected from three stations (Borj Islam, Al madina al riyadiah and Jableh), the total of fishes were / 255 / individuals. All fish individuals were classified, preserved and placed at the High Institute of Marine Research Laboratory, some biological factors of the collected fish (K%, GSI%,HIS%) were studied. Results had revealed the presence of five species of Puffer Fish belong to three genera of Tetraodontidae: Lagocephalus sceleratus, L. spadiceus, L. suezensis, Sphoeroides pachygaster, Torquigener flavimaculosus. S. pachygaster species (migratory species from the Atlantic Ocean to the Mediterranean Sea) has been recorded for the first time in the marine water of Syria. Results showed that L. suezensis were more coincidence species in the catch. The amounts caught of Puffer Fishes varied according to the stations; the highest was in Borj Islam. K% was almost similar in all species, while GSI% and HSI% varied according to the species and seasons.

Biodiversity and abundance of Planktonic Cnidaria (Siphonophorae ) in Lattakia Port

In this paper the preliminary study were conducted on the Cnidaria (Siphonophorae) in the Commercial port of Latakia city between November 2013 and August 2014. Nine species of Siphonophorae were identified, most of them listed during February 2014. The most abundant species are : Eodoxoides spiralis and Bassia bassensis ; Chelophyes contorta is the lowest abundance species and were recorded for the first time in Syrian costal water. The highest abundance of Cnidaria were recorded during May with average 130 ind./100m3 , 98% of this average belong to Siphonophorae , whereas the lowest abundance recorded at August (1 ind./ 100m3) , in May the highest abundance of Siphonophorae (426 individual / 100 m3) in the station St2 were recorded. The most diverse and abundance station was St.2 (Far off the pollution source ) , while the station St.1(Exposed to direct pollution) was least in abundance and diversity of siphonophorae.

The Handling Impact from Catch to Consumer on Quality and Safety: e.g. Sea Bass ‘Dicentrarchus Labrax’

The aim of this study was to evaluate the effect of handling on the quality and safety of Sea Bass, Dicentrarchus labrax. The samples were collected from the marine waters of Tartous, and were traced from catch till arrival to consumers. Sensorial and microbial examinations during fish handling were done, and some physical and chemical characteristics of waters in the fishing area were determined. The results showed that the sensorial characteristics differed during fish handling and started to decrease in the marketplace. The results also showed that the number of microorganisms increased during fish handling and reached the highest level in the marketplace. This increase was observed particularly in summer. The gills were the most infected part by handling followed by the scales and then the eyes. The microbial results also showed the presence of gram positive bacteria such as Staphylococcus Aureus, and gram negative bacteria such as Escherichia coli, Proteus sp., Salmonella spp., Shigella sp., Pseudomonas spp.. The market was the most infecting with these microbes.

Study Of Ability Of Proteus volgaris To Degrade Petroleum Alkane Chains Of Compounds Polluting Marine Environment

Proteus volgaris was isolated from costal sea water of Lattakia city port, as it is contaminated with petroleum compositions coming from marine transportations activities. The ability of this bacteria to degrade the petroleum alkanes was studied by using different concentrations of petroleum as sole source of carbon and energy. The gas chromatography (GC) technique was used to measure the concentration of alkanes. Results showed that the isolated bacteria were able to degrade different alkanes chains. The ratio of biodegradation of C12, C16, C18 were 96.75%, 78.59%, 97.27% respectively, while the rate of biodegradation of the entire amount of alkanes was 77.14% in 10 mg/ml polluting concentration. The percentage of biodegradation at concentration 75 mg/ml of petroleum was 17.26%. Therefore, the high ability of Proteus volgaris to degrade the long chains alkanes recommended it to be effective in the bioremediation process of the contaminated marine environments.
