Primary culture of gilthead sea bream skeletal muscle cells was used to examine the effects of growth hormone (GH) and insulin-like growth factors (IGFs) in fish muscle proliferation and growth. Proliferation was measured as the percentage of positive cells expressing the proliferating cell nuclear antigen (PCNA) analyzed by immunocytochemistry. First, the effects of GH from two different origi...

The aim of this work was to underline the physiological role of the antioxidant peroxiredoxin (PRDX) family in gilthead sea bream (Sparus aurata L.), a perciform fish extensively cultured in the Mediterranean area. First, extensive BLAST searches were done on the gilthead sea bream cDNA database of the AQUAMAX European Project (www.sigenae.org/iats), and six contigs were unequivocally identifie...

The rock bream (Oplegnathus fasciatus) is considerably one of the most economically important marine fish in East Asia and has a unique neo-Y chromosome system that is a good model to study the sex determination and differentiation in fish. In the present study, we used Illumina sequencing technology (HiSeq2000) to sequence, assemble and annotate the transcriptome of the testis and ovary tissue...

Bone deformities in several fish species, like gilthead sea bream (Sparus aurata), are currently a major problem in aquaculture. To gain knowledge of fish skeletal development, a primary cell culture has been established from sea bream vertebra. The initial fibroblastic phenotype of the cells changed to a polygonal shape during the culture, and the addition of an osteogenic medium promoted the ...

The aim of this study is to determine suitable conditions for egg disinfection of gilthead sea bream (Sparus aurata), red porgy (Pagrus pagrus), and common dentex (Dentex dentex) with glutaraldehyde, hydrogen peroxide and iodine. The eggs were disinfected with 200 ppm glutaraldehyde (T= 2, 4, 8, 16 min), 300 ppm hydrogen peroxide and iodine (T= 5, 10, 15, 20 min) at four different contact times...

BACKGROUND ICI 182,780 (ICI) belongs to a new class of antiestrogens developed to be pure estrogen antagonists and, in addition to its therapeutic use, it has been used to knock-out estrogen and estrogen receptor (ER) actions in several mammalian species. In the present study, the effects and mechanism of action of ICI were investigated in the teleost fish, sea bream (Sparus auratus). METHODS...

We studied the effects of inter-annual variability and serial correlation on the statistical power of monitoring schemes to detect trends in biomass of bream (Abramis brama) in Lake Veluwemeer (The Netherlands). In order to distinguish between 'true' system variability and sampling variability we simulated the development of the bream population, using estimates for population structure and gro...

Yellowfin seabream, Acanthopagrus latus , is one of the most important species in terms stock enhancement China. However, using metagenomic techniques to explore feeding habits and stomach microbiome yellowfin seabream still rare. The objective this work was study sea bream from Daya Bay through analysis different weight classes (?50, 50–100, >100 g). Whole-metagenome shotgun sequencing ...

A giant meront containing thousands of merozoites has been found in the intestinal epithelium of an adult specimen of white bream (Blicca bjoerkna). The taxonomic position of this unusual coccidian stage is discussed.

The content of heavy metals in fish different ecological groups the conditions Argazinsky reservoir (Russia) has been studied, its safety when used as a product nutrition was given. material study “local” (bream, pike, perch, roach, whitefish) caught by fishermen. determined atomic absorption method. Compared to muscular tissue, bone tissue found accumulate more manganese, zinc, cadmium, lead, ...
