Fish fortification with iodine-rich macroalgae (Laminaria digitata) and Selenium-rich yeast is expected to promote nutritional added value of this crucial food item, contributing a healthy balanced diet for consumers. However, it not known if steaming can affect these nutrient levels in fortified fish. The present study evaluates the effect on nutrients contents farmed gilthead seabream (Sparus...

study was undertaken to establish the optimum dietary indispensable amino acid (IAA) profile for yellow fin seabream broodstock based on the amino acid (AA) profile of broodstock, eggs and larvae of Acanthopagrus latus. Three isonitrogenous (40%) and isolipid (20%), named diets 1, 2 and 3 were formulated with different ratios of total essential amino acids per total non-essential amino acid...

1. While the reasons for group-living have been studied for decades, little is known about why individuals become solitary. 2. Several previous experimental studies could demonstrate that group-living can arises as a consequence of ecological constraints. 3. It has been argued that reproductive competition between group members leads to significant costs of group-living, being a main reason of ...

Alternative reproductive tactics of males have been studied in many species, but few studies have focused on females. In many communally breeding mammals, females can be adult non-breeding helpers, leave the group and breed solitarily, or they could be a breeder in their natal group, representing three alternative reproductive tactics. The reasons for delayed breeding are not well understood, b...

Nervous necrosis virus (NNV), also known as betanodavirus, has been recently implicated in mass mortalities of cultured marine fish. An effective vaccine is urgently needed to protect fish against this virus. However, parenteral immunization methods are very stressful. Individual immunization for thousands of fish is very labor intensive and expensive. Therefore, we expressed NNV coat protein i...

The draft genome sequence of the nervous necrosis virus (NNV) SGYeosu08, isolated from sevenband grouper (Epinephelus septemfasciatus) in Yeosu, South Korea, was cloned and analyzed. The full-length RNA1 was a 3,103-nucleotide-encoding region of RNA-dependent RNA polymerase, and the RNA2 encoding a coat protein was 1,433 nucleotides in length. This genome sequence might be useful in the develop...

The identification of the genetic basis domestication in fish species is timely importance for aquaculture industry order to increase productivity, quality, and welfare farmed fish. goal this study investigate largely unknown aquaculture-induced evolution gilthead seabream, which one most important Mediterranean region. We used a panel 1159 genome-wide SNPs, genotyped 956 from 23 wild populatio...

In a first part, we are concerned with the relationships between polynomials in the two generators of the algebra of Heisenberg–Weyl, its Bargmann–Fock representation with differential operators and the associated one-parameter group. Upon this basis, the paper is then devoted to the groups of Riordan matrices associated to the related transformations of matrices (i.e. substitutions with prefun...

Depending on the growth conditions, FePd thin films can display a perpendicular magnetic anisotropy associated with chemical order. In competition with the shape anisotropy, this can lead to striped magnetic domains, with moments perpendicular to the film plane. Under these circumstances, magnetic flux closure should occur. The striped domains were studied with soft x-ray resonant magnetic scat...
