An analytical method involving anion exchange high performance liquid chromatographic determination of vitellogenin (Vtg) in fish plasma after postcolumn fluorescence derivatization with o-phthalaldehyde (OPA) was developed. The retention time of Vtg was about 11 min. The reagent variables for derivatization were optimized. The fluorophore was excited at 335 nm and detected at 435 nm. A calibra...

Large-scale gene expression studies were performed for one of the main European aquaculture species, the gilthead sea bream Sparus auratus L. For this purpose, a cDNA microarray containing 10,176 clones from a cDNA library of mixed embryonic and larval stages was constructed. In addition to its importance for aquaculture, the taxonomic position and the relatively small genome size of sea bream ...

In the sea bream Sparus auratus three stage-specific fast troponin T (fTnT) isoforms have been cloned and correspond to embryonic-, larval- and adult-specific isoforms. Characterisation, using database searches, of the putative genomic organisation of Fugu rubripes and Tetraodon nigroviridis fTnT indicates that alternative exon splicing in the 5 region of the gene generates the different isofor...

Bream (Abramis brama, Berg, 1949; Family: Cyprinidae) is commercially valuable fish in the Caspian Sea fishing industry. Iranian Fisheries Organization annually produces and release up to 19 million Bream fries size for recruiting of this species. Its fries are mostly released into the Anzali wetland with 4 ppt salinity. Meanwhile, they sometimes are released into Sefidrood River (0.5 ppt), Sef...

Rhabdovirus was isolated from wild common bream Abramis brama during a disease outbreak with high mortality in Northern Ireland during May 1998. Rhabdovirus was also isolated at the same time from healthy farmed rainbow Oncorhynchus mykiss and brown trout Salmo trutta on the same stretch of river and 11 mo later from healthy wild bream and roach Rutilus rutilus in the same river system. Experim...

In archived samples from the German environmental specimen bank (ESB) organotin compounds including tributyltin (TBT) and triphenyltin (TPT) as well as their potential degradation products were quantified. Muscles of bream (Abramis brama) sampled in the period 1993-2003 from the rivers Rhine, Elbe, Saale, Mulde, Saar, and from Lake Belau (period 1988-2003) were analyzed by gas chromatography/at...

Salinities in some normally-closed estuaries in the central south coast of Western Australia are now frequently becoming highly elevated. This is due to: (1) high evaporation rates in water volumes that, by summer, are already low as a result of atypically dry winters; and (2) increased salt run-o¡ following vegetation clearing in the catchments. A few black bream (Acanthopagrus butcheri) died ...

Since 1990, red sea bream iridovirus (RSIV) has caused high mortalities in the summertime in cultured red sea bream Pagrus major in southwest Japan. To establish control measures for red sea bream iridoviral disease (RSIVD), the effectiveness of a formalin-killed viral vaccine was evaluated in a field trial. Two groups each consisting of 1000 juvenile red sea bream were either intraperitoneally...

Sci., Supplement 1: 62–71 The paper presents a comparative analysis of proximate and fatty acid composition of seven fi sh species from the Danube River including asp (Aspius aspius), common bream (Abramis brama), common barbe...

A new species of threadfin bream, Nemipterus flavomandibularis, from the Western Indian Ocean is described and figured. The new species appears most closely related to N. bipunctatus (Valenciennes), but differs principally in colour pattern: N. flavomandibularis is distinct from N. bipunctatus in having two yellow bands on the snout, the upper lip narrowly edged with yellow; and lower lip and c...
