“…1). These results are in agreement with previous findings on other common dentex egg biochemical factors, e.g., lipids (Samaee et al, 2009b), FAAs , and fatty acids (Samaee and Estévez,201 Ib). This finding might indicate that the PAA ratios provide a better opportunity to understand the complexities of biological relationships between egg biochemical content and the process of development of the embryo and/or larva in common dentex (and perhaps other marine pelagophil teleosts).…”

“…1) is markedly higher than those of corresponding results previously found for other intrinsic biochemical factors of common dentex eggs, e.g., Vtg-derived proteins (r2 = 0.095-0.634; mean ± SD = 0.230 ± 0.145; C.V. = 63%; Samaee et al, 2009a), lipid (r^ = 0.459-0.739; mean ± SD = 0.607 ± 0.130; C.V. = 21.41%) and fatty acids (r^ = 0.641-0.859; mean ± SD = 0.729 ± 0.053; C.V. -7.27%; Samaee et al, 2009b), carbohydrate metabolites and enzymes (r^ = 0.184-0.490; mean ± SD = 0.288 ± 0.087; C.V. = 30.20%; Giménez et al, 2006), FAAs (r^ = 0.605-0.875; mean ± SD = 0.700 ± 0.062; C.V. = 8.85%; Samaee et al, 2010), and non-Vtg-derived proteins (Samaee et al, unpublished data). These contrasting results might indicate that PAAs have a higher and more direct effect on embryogenesis and larval development and can be considered better predictors of embryo/larva success.…”

This study represents the initial attempt to evaluate the effect of egg protein-bound amino acid (i.e., vitellogenin-derived PAAs) content on embryo/larva success in Dentex dentex. Viable eggs were obtained from a single female (i.e., intra-individual analysis) in captivity. Selected embryo/larva viability parameters (the egg floating rate, the hatching rate, and the larval survival rate at days 0 to 5 post-hatch) were determined. The egg batches were categorised in three groups (high-, medium-, and low-quality batches) based on the magnitude of their hatching rates. The protein-bound amino acid content of biometrically similar egg batches of varying quality was analysed. The content values for 12 proteinbound amino acids (i.e., essential PAAs: Thr, Met, Arg, Ile, Val, Phe, His; non-essential PAAs: Ala, Glu, Gly, Asp, and Ser) were significantly correlated with the embryo/larva viability parameters in an analysis performed in terms of their ratios. The egg protein-bound amino acid content was significantly correlated with the dentex larval survival rate at 3 and 5 days post-hatch, a critical period of survival that is problematic during the propagation of this species in captivity. The results of this study also offer statistical evidence for the effects of the interrelationships of the egg protein-bound amino acids on the relationships between the quantitative composition of the protein-bound amino acids and the viability parameters.

Profitability of fish farming can be undermined by a suite of biological constraints. Effects of these constraints on the biology of the animal, the functioning of a tissue, or the quality of the final filleted product can be detected with very sensitive hi-tech approaches, grouped by the term '-omics'. These -omics technologies further present powerful tools for the genetic selection of diverse traits and, as such, will contribute substantially to the future development of the aquaculture sector. Sustainability issues of importance to the industry, such as environmental impacts, use of therapeutants, fish health management and fishmeal replacement, can again be aided, at least in part, through the effective use of -omics technologies. It thus appears that -omics technologies may be a key tool for the responsible growth of intensive aquaculture in the 21st century. In this paper we review the current status of -omics technologies and the potential for application within the aquaculture industry.

“…If fact, diet design for fattening focuses on growth and efficiency, whereas for breeders, the main objective is obtaining high quality eggs. The relationship between egg biochemical composition and embryo and larval quality has been described (Rodriguez, Pérez, Izquierdo, Mora, Lorenzo & Fernández-Palacios 1993;Almansa, Pérez, Cejas, Badía, Villamandos & Lorenzo 1999;Samaee, Estévez, Giménez & Lahnsteiner 2009), indicating that the biochemical composition of fish eggs is speciesspecific and varies both qualitatively and quantitatively, and that some lipid components could be related to differences in spawning quality. Lipids play a significant role in fish nutrition (Sargent, McEvoy, Estevez, Bell, Bell, Henderson & Tocher 1999).…”

Effects of two diets on lipid composition and reproductive performance of brill (Scophthalmus rhombus) eggs

et al. 2011

The effects of two diets with different lipid composition (squid Loligo gahi and one commercial pellet for breeders) on reproductive performance and egg lipid composition of brill (Scophthalmus rhombus) were compared. A total of 36 adult brill weighing 1482 ± 432 g were randomly distributed in the experimental tanks. A flow‐through system composed of four tanks with 4.2 m2 of bottom area (5.0 m3 × 1.2 m water depth) was used. The experiment lasted for approximately 5 months (168 days). From the four mature females fed squid, three ovulated. Five females fed pellets matured and ovulated. Total ovulations were of 10 and 44, by the three females fed squid and the five ovulating female fed pellets respectively. Egg viability was higher, although not significantly, for females fed pellets. This indicates that pellets could be a better food for breeding females. In general, the egg total lipid content and the lipid classes composition did not seem to be affected by diet. In contrast, results indicate that not only diets but also individual females, regardless of the diet consumed, are determinant for egg fatty acid composition, clearly modulating their composition.
