| the morphological and molecular characterization of myxobolus khaliji n. sp. (myxozoa: myxosporea) from the double bar seabream acanthopagrus bifasciatus (forsskål, 1775) in the arabian gulf, saudi arabia. | myxobolus khaliji n. sp., a new myxosporean, is described from the intestinal wall of the double bar seabream acanthopagrus bifasciatus, collected from the arabian gulf off the coast of saudi arabia. it is characterized by the presence of ellipsoidal or round plasmodia of 2-4 mm in diameter. mature spores were subspherical to elliptical in the frontal view, with a slightly pointed anterior end and a bluntly rounded posterior end, and measured 8.1 ± 0.4 (7.2-9.5) μm long, 6.3 ± 0.6 (5.1-7.4) μm w ... | 2014 | 24802863 |
| scale characteristics of two fish species, acanthopagrus bifasciatus (forsskål, 1775) and rhabdosargus sarba (forsskål, 1775) from the red sea at jeddah, saudi arabia. | the present work aimed to screening and documenting the diversity of scale characteristics of two species belonging to two different genera of the family sparidae: acanthopagrus bifasciatus and rhabdosargus sarba from the red sea. the valid useful scale characters for systematic purposes were determined in the term of morphometry and scanning electron microscopic techniques. a wide spectrum of size-free intraspecific variations between different body regions was recorded in each species in terms ... | 2013 | 24494517 |
| preliminary report on the levels of elements in four fish species from the arabian gulf of saudi arabia. | this manuscript presents preliminary information on the concentrations of heavy metals: cadmium, lead, nickel, vanadium and arsenic in 66 fish samples of four different species collected from three different sites on the gulf coast of saudi arabia where there are agricultural, municipality and petroleum industrial activities. fish species; highly consumed by the local population were selected: emperors, rabbitfish, doublebar-bream and greasy-grouper to ascertain the fish quality for human consum ... | 2002 | 12201205 |
| trematodes from red sea fishes: neohypocreadium aegyptense n. sp. (lepocreadiidae), fairfaxia cribbi n. sp. and macvicaria chrysophrys (nagaty & abdel-aal, 1969) (opecoelidae). | specimens of the marine fishes chaetodon lineolatus (chaetodontidae), lethrinus nebulosus (lethrinidae) and acanthopagrus bifasciatus (sparidae) were caught in the red sea off the coast of sharm el-sheikh, south sinai, egypt. fifteen (75%), four (16%) and fourteen (35%) fish, respectively, were found to harbour intestinal trematodes. c. lineolatus was parasitised by neohypocreadium aegyptense n. sp. (lepocreadiidae), l. nebulosus by fairfaxia cribbi n. sp. (opecoelidae) and a. bifasciatus by mac ... | 2005 | 16315080 |
| gas chromatography-mass spectrometric determination of polycyclic aromatic hydrocarbons in five species of fish from three sites in the arabian gulf. | a gas chromatography-mass spectrmetroic (gc-ms) method was developed to measure six polycyclic aromatic hydrocarbons (pahs) in 54 fish samples. five fish species highly consumed by the local population (shrimps, emperors, rabbitfish, doublebar bream and greasy grouper) were selected from three different sites on the gulf coast of saudi arabia where agricultural, municipal and petroleum industry activities take place. variations in pah levels among the three sites were not significant. total conc ... | 2002 | 12400558 |

| review of the acanthopagrus latus complex (perciformes: sparidae) with descriptions of three new species from the indo-west pacific ocean. | acanthopagrus latus, long considered a single valid indo-west pacific ocean species, characterized by having yellow pelvic, anal and caudal fins, is reviewed and separated into a. latus (east asian shelf) and acanthopagrus longispinnis (bengal bay), and three new species: acanthopagrus morrisoni sp. nov. (north-western australia), acanthopagrus arabicus sp. nov. [middle east (except for the red sea) to coasts of iran and pakistan, and western indian coast] and acanthopagrus sheim sp. nov.

| differentiation of sparidae species by dna sequence analysis, pcr-sscp and ief of sarcoplasmic proteins. | the increasing global trade of fishery and aquaculture products makes it necessary to develop methods for species identification in case of fish fillets or other highly processed seafood with external morphological characteristics (e.g. gills, fins) of the original fish being removed. species identification methods based on dna- or protein-analysis, like dna sequencing of pcr products, pcr-sscp (polymerase chain reaction - single strand conformation polymorphism), and isoelectric focusing (ief) ... | 2013 | 23265470 |
| morphology, phylogeny and seasonal prevalence of ceratomyxa arabica n. sp. (myxozoa: myxosporea) infecting the gallbladder of acanthopagrus bifasciatus (pisces: sparidae) from the arabian gulf, saudi arabia. | a new myxozoan species was recovered from the gallbladder of acanthopagrus bifasciatus from the arabian gulf in saudi arabia. the overall prevalence of infection was 28.6 % (32/112), with the highest prevalence 42.9 % (12/28) in winter and 10.7 % (3/28) as the lowest in autumn. the new species is described using its morphological characteristics and small subunit (ssu) rdna. spores of ceratomyxa arabica n. sp. are stubby-shaped with unequal shell valves, 8 (7-9) μm in length × 12 (10-14) μm in t ... | 2015 | 25367211 |
