Juvenile black sea bream, Acanthopagrus schlegelii, were exposed to waterborne zinc (Zn) at concentrations of 0, 200, and 400 μg/L, at temperatures of 18 or 26 °C for 4 weeks. Superoxide dismutase (SOD) activities in the liver and gill of A. schlegelii significantly increased following exposure to waterborne Zn. Significant reduction in glutathione S-transferase (GST) activity in the liver and ...

Hepcidin is known to be expressed in fish with bacterial challenge and iron overload. Here we first report the hepcidin expression induced in the developmental stages from embryo to fry of red sea bream (Pagarus major) and in juvenile black porgy (Acanthopagrus schlegelii B.) upon continuous waterborne exposure to BaP. The gene expression of CYP1A1 and IgL (immunoglobulin light chain) were both...

A new species, Myrsidea willardi, is described from the Schlegel’s Asity, Philepitta schlegeli, from Madagascar. The only previously described species from the host family Philepittidae, Myrsidea minuscula (Piaget), is redescribed and illustrated. These two species of lice show pronounced genetic divergence based on partial mitochondrial cytochrome oxidase I sequences.

The relationships between otolith score, a function of increasing stain visibility, and the ratio of alizarin complexone (mg) to fish biomass (g) for 0.1, 0.6 and 7 g black bream Acanthopagrus butcheri show that acceptable marks are produced in all size classes using a stain-to-biomass ratio of 3.3 mg g(-1) following an immersion period of 24 h.

Yellow finned sea bream (Acanthopagrus arabicus) is a commercially important fish of coastal water Pakistan. It widely consumed by the people within and outside country. Therefore, paper investigates concentration macro-minerals (Ca, K, Mg Na) in its meat gills. The concentrations different elements demonstrated statistically significant difference (P < 0.01) between gills fish. Significantl...

A bacterium designated M1-1 was isolated from the gills of a Korean rockfish, Sebastes schlegeli Hilgendorf, after high hydrostatic pressure processing. Studies of 16S rRNA phylogeny and comparative genomics demonstrated that the isolate belongs to Staphylococcus saprophyticus subsp. saprophyticus. Here, we report the draft genome sequence of S. saprophyticus subsp. saprophyticus M1-1 (KACC 165...

Using the outline analysis of otolith to study stocks predominant species genus Acanthopagrus (Sparidae family) in Persian Gulf and Oman Sea

Recent studies have indicated that ghrelin stimulates growth hormone release from the pituitary via the growth hormone secretagogue receptor (GHSR). We have previously isolated two GHSR subtypes from the pituitary of the black seabream Acanthopagrus schlegeli. In the present study, we have cloned and characterized ghrelin from the same fish species at both the cDNA and gene levels. The full-len...

Estrogen receptors (ER) play a crucial role in mediation of estrogen activities. Here we report the isolation and expression analysis of ERβ1 and ERβ2 from ovary Korean rockfish (Sebastes schlegeli). were isolated using reverse transcription-polymerase chain reaction (PCR) and rapid amplification of cDNA ends procedures. The cDNA of this study, ERβ1 (588 amino acids) and ERβ2 (659 amino acids) ...
