List of validated primers of gilthead sea bream (Sparus aurata) and European seabass (DIcentrarchus labrax) developed in PerformFISH project (D2.3)
<p>The document contains all the primers identified for the screening of genes tested for their potential as biomarkers to predict quality performance in gilthead sea bream and European sea bass larvae and juveniles in the context of PERFORMFISH (WP2). The spreadsheet has the following information: Pathway, phisiologic process in which the gene is involved; name of protein that gene produces; gene code; acession nº, code given in the consulted databases and the sequence extracted for primer design; FW and RV primer, forward and reverse primer sequence specific for target gene; melt temperature, optimized temperature that primers work at ; amplicon size, size in base pairs of the product produced with the primers; eff%, efficency of primers; r2; source, the origin of the primers, "in house" or "literature" (including available DOI. Each pair of primers are classified using a "traffic light" system indicating their validation status.</p>
Data from: Balanced replacement of fish meal with Hermetia illucens meal allows efficient hepatic nutrient metabolism and increased fillet lipid quality in gilthead sea bream (Sparus aurata) juveniles
<p>In the present study, gilthead sea bream (<em>Sparus aurata</em>) juveniles were reared using sustainable feeds containing insect meal from <em>Hermetia illucens</em> larvae and poultry by-products meal. Proteomics and Proton Nuclear Magnetic Resonance-based metabolomics analysis were used to assess the metabolic impact of tested dietary formulations in sea bream liver, whereas the composition of muscle fillet was characterized by means of metabolomics and gas chromatography of fatty acids methyl esters. Replacing fish meal with insect meal in a 5% fish meal diet did not substantially alter metabolism of dietary nutrients, leading to small but statistically detectable effects solely on lauric acid content of sea bream fillet, and few alterations in some markers of immune response, such as leukocyte elastase inhibitor-like, granzyme B (G,H)-like, and two associated ortholog groups namely serpin B, and chymase). Liver morphology confirmed the absence of structural damage or inflammation in the insect meal-fed group, which showed a lower amount of hepatic lipid deposition and accumulation, too.</p>

Data from: Exploring neutral and adaptive processes in expanding populations of gilthead sea bream, Sparus aurata L., in the North-East Atlantic
Recent studies in empirical population genetics have highlighted the importance of taking into account both neutral and adaptive genetic variation in characterizing microevolutionary dynamics. Here we explore the genetic population structure and the footprints of selection in four populations of the warm-temperate coastal fish, the gilthead sea bream (Sparus aurata), whose recent northward expansion has been linked to climate change. Samples were collected at four Atlantic locations, including Spain, Portugal, France and the South of Ireland, and genetically assayed using a suite of species-specific markers, including 15 putatively neutral microsatellites and 23 Expressed Sequence Tag-linked (ESTs) markers, as well as a portion of the mitochondrial DNA (mtDNA) Control Region. Two of the putatively neutral markers, Bld-10 and Ad-10, bore signatures of strong directional selection, particularly in the newly established Irish population, though the potential 'surfing effect' of rare alleles at the edge of the expansion front was also considered. Analyses after the removal of these loci suggest low but significant population structure likely affected by some degree of gene flow counteracting random genetic drift. No signal of historic divergence was detected at mtDNA. BLAST searches conducted with all 38 markers used failed to identify specific genomic regions associated to adaptive functions. However, the availability of genomic resources for this commercially valuable species is rapidly increasing, bringing us closer to the understanding of the interplay between selective and neutral evolutionary forces, shaping population divergence of an expanding species in a heterogeneous milieu.
Data from: Microsatellite length variation in candidate genes correlates with habitat in the gilthead sea bream Sparus aurata
The genetic basis and evolutionary implications of local adaptation in high gene flow marine organisms are still poorly understood. In several Mediterranean fish species, alternative migration patterns exist between individuals entering coastal lagoons that offer favorable conditions for growth and those staying in the sea where environmental conditions are less subject to rapid and stressful change. Whether these coexisting strategies are phenotypically plastic or include a role for local adaptation through differential survival needs to be determined. Here, we explore the genetic basis of alternate habitat use in western Mediterranean populations of the gilthead sea bream (Sparus aurata). Samples from lagoonal and open sea habitats were typed for 3 candidate gene microsatellite loci, 7 anonymous microsatellites and 44 AFLP markers to test for genotype-environment associations. While anonymous markers globally indicated high levels of gene flow across geographic locations and habitats, non-neutral differentiation patterns correlated with habitat type were found at two candidate microsatellite loci located in the promoter region of the Growth hormone and Prolactin genes. Further analysis of these two genes revealed that a mechanism based on habitat choice alone could not explain the distribution of genotype frequencies at a regional scale, thus implying a role for differential survival between habitats. We also found an association between allele size and habitat type, which, in the light of previous studies, suggests that polymorphisms in the proximal promoter region could influence gene expression by modulating transcription factor binding, thus providing a potential explanatory link between genotype and growth phenotype in nature.
