Organogenesis of the liver in sea bream
Journal of Fish Biology, 1995Development of the liver in sea bream, Sparus aurata, was studied using light and electron microscopy from hatching to the age of 23 days. Histochemical reactions were used to monitor changes in lipids and glycogen during this period. During the strictly endotrophic prelarval phase from hatching until mouth‐opening, the primordial liver formed by ...

Exploring consumer’s preferences for farmed sea bream
Aquaculture International, 2012Sea bream (Sparus aurata) production plays a significant part in Italian aquaculture, contributing to almost 18% of national pisciculture sales revenue. In recent years, Italian firms faced higher competition from countries with lower production costs. This prompted responses toward both cost reduction and product differentiation. The objective of this

Apoptosis in sea bream Sparus aurata eggs
Molecular Reproduction and Development, 2003AbstractIn the present study, the sea‐bream Sparus aurata, a pelagic egg spawner, was used as experimental model, in order to establish the occurrence of apoptosis in vertebrates with external reproduction. The same female ovulates floating and nonfloating eggs, but only the former, after fertilization, proceed to embryo development.

Hormonal Control of the IGF System in the Sea Bream Ovary
Annals of the New York Academy of Sciences, 2005Abstract: Numerous studies have described the presence of an intragonadal IGF system involved in regulation of gametogenesis in teleost fish. In the present study, the in vivo effects of estradiol‐17β (E2) and growth hormone (GH) exposure on IGF‐I, IGF‐II, IGF1R, and IGFBP2 gene expression in sea bream ovary were monitored by RT‐PCR during ...

Histological and Biochemical Observations of Developing Enameloid of the Sea Bream
Advances in Dental Research, 1987In order to study changes in the enameloid matrix of the Sea Bream during the course of its development, we selected the developmental tooth germs of this fish as representative of three different developmental stages: "chalk-like", "cheese-like", and "soft" enameloid. The protein, calcium, and phosphate contents of each sample were analyzed.

Noncollagenous Proteins of Sea Bream Dentine
1991The most interesting noncollagenous proteins for mineralization in mammalian dentine are at present thought to be the highly phosphorylated protein, phosphophoryns which may be involved in regulating the ordered deposition of apatite crystals[l].

An overview of aquaculture in Turkey: With emphasis on sea bass and sea bream
Aquaculture Economics & Management, 2000Abstract Aquaculture is a relatively recent industry in Turkey, enjoying great potential for development. Both freshwater and marine aquaculture are being practised in over 800 operational units. Rainbow trout (Oncorhynchus mykiss), Sea bream (Sparus aurata), Sea bass (Dicen‐trarchus labrax), comprise 90% of the total production, together with Atlantic

Ultrasonographic Assessment of Thawing in Sea Breams (Sparus aurata)
2011To assess sea bream (Sparus aurata) thawing, two ultrasonographic (US) protocols were used. The first protocol was used on 15 subjects at three different times (1) immediately after capture, (2) after the first thaw, and (3) after the second thaw. A general-purpose device equipped with a linear high-frequency probe was used.
