“…In the eastern Mediterranean Sea, S. maxima has been reported from the coastal waters of Egypt (Abdel-Aziz & Aboul-Ezz, 2003) and the north Levantine Sea (Mutlu, 2005). The species was not collected at three sites of the Levantine Sea (south of Kriti and Cyprus) in June 1993 (Weikert & Godeaux, 2008) and its presence is hitherto unknown in other regions of the eastern Mediterranean Sea.…”

Based on recent biodiversity studies carried out in different parts of the Mediterranean, the following 19 species are included as new records on the floral or faunal lists of the relevant ecosystems: the green algae Penicillus capitatus (Maltese waters); the nemertean Amphiporus allucens (Iberian Peninsula, Spain); the salp Salpa maxima (Syria); the opistobranchs Felimida britoi and Berghia coerulescens (Aegean Sea, Greece); the dusky shark Carcharhinus obscurus (central-west Mediterranean and Ionian Sea, Italy); Randall's threadfin bream Nemipterus randalli, the broadbanded cardinalfish Apogon fasciatus and the goby Gobius kolombatovici (Aegean Sea, Turkey); the reticulated leatherjack Stephanolepis diaspros and the halacarid Agaue chevreuxi (Sea of Marmara, Turkey); the slimy liagora Ganonema farinosum, the yellowstripe barracuda Sphyraena chrysotaenia, the rayed pearl oyster Pinctada imbricata radiata and the Persian conch Conomurex persicus (south-eastern Kriti, Greece); the blenny Microlipophrys dalmatinus and the bastard grunt Pomadasys incisus (Ionian Sea, Italy); the brown shrimp Farfantepenaeus aztecus (north-eastern Levant, Turkey); the blue-crab Callinectes sapidus (Corfu, Ionian Sea, Greece). In addition, the findings of the following rare species improve currently available biogeographical knowledge: the oceanic pufferfish Lagocephalus lagocephalus (Malta); the yellow sea chub Kyphosus incisor (Almuñécar coast of Spain); the basking shark Cetorhinus maximus and the shortfin mako Isurus oxyrinchus (north-eastern Levant, Turkey).

“…In the Egyptian Mediterranean waters, Dowidar (1965) reported 99 and Hussein (1997b) 11 species off Alexandria coast, while Abdel-Aziz and Aboul-Ezz (2003) and Abdel-Aziz (1997) identified 37 and 31 species, respectively, along Alexandria coast. In the studies conducted in harbour waters of Egypt, Abdel-Aziz (2000) reported 29 species from Dekhaila Harbour, Abdel-Aziz (2002) reported 40 species from Western Harbour, AbdelAziz (2004) identified 28 species from Eastern Harbour and Dorgham et al (2009) mentioned 37 species from Damietta Harbor.…”

Seasonal variations in species composition, abundance and biomass of tintinnids (Protozoa: Ciliata) were investigated in the Western Harbour, seasonally during 2012. There were remarkable seasonal variations in environmental parameters, phytoplankton concentrations and abundance and biomass of tintinnids: highest in spring and lowest in autumn. Annual average abundance and biomass of tintinnids were 8.435 ind. l(-1) and 3.725 μg C l(-1), respectively. A total of 29 species of tintinnids belonging to 11 genera was identified. Of which, Tintinnopsis was the most abundant genus in terms of number of species (9), but Favella was the best quantitatively (89% of the total tintinnids). The overall mean abundance and biomass were highest (mean 24.415 ind. l(-1) and 10.355 μg C l(-1), respectively) during spring than the remaining seasons. Due to significant positive relationship between the total biomass of tintinnids and phytoplankton concentrations, food supply is not a problem for tintinnids harbouring in the Western Harbour. Hence, predation loss by meso- and macrozooplankton might be the possible reasons for the estimated low biomass of tintinnids in the present study. Some of the seasonal environmental factors as water salinity, nitrite, dissolved oxygen and pH values exert an influence on the species composition, abundance and biomass of tintinnids.

“…According to the obtained data in several zooplankton studies along the Egyptian coasts (Abdel-Aziz;2004;Abdel-Aziz and Aboul-Ezz, 2003;Anon, 2007), protozoa are considered as important biotic components in the aquatic ecosystem, particularly those acting as predators of bacteria and other micro-organisms beside some rotifers. They provide nutritive source for organisms at higher trophic levels (Kneitel and Chase 2004;Dopheide et al, 2009), increase mineralization to make nutrients more available to other organisms (Vickerman, 1992).…”

Prevalence of the protozoan organisms in the Red Sea, Hurghada, Egypt

This study was carried out in order to evaluate the distribution and availability of the various protozoan organisms in some stations at Hurghada on the Egyptian coast of the Red Sea beside their response to some of the physico-chemical parameters. Two main phyla were detected at these sampling stations; Ciliophora and Sarcomastigophora. The latter phylum is comprising two subphyla (Mastigophora and Sarcodina). Three various classes were detected in that phylum; Rhizopodea, Actinopodea and Phytomastigophorea. Three different classes of the ciliated protozoa were identified as well which are known as Kinetofragminophorea, Oligohymenophorea and Polyhymenophorea. The different classes of the protozoan organisms comprised too many orders (more than 24 orders) which were illustrated by more than 103 genera/ species. It was proved that certain physico-chemical parameters affect the prevalence of some of these protozoan organisms significantly from the statistical point of view. Simultaneously, time -series analysis proved the presence of cyclic changes in the physico-chemical parameters, protozoan abundance and their numerical densities which fluctuate with the time. This could be interpreted as a result of the presence of a chemostate situation.
