Animal domestication is a process of environmental modulation and artificial selection leading to permanent phenotypic modifications. Recent studies showed that changes occur very early in domestication, i.e., within the first generation captivity, which raises hypothesis epigenetic mechanisms may play critical role on onset domestic phenotype. In this context, we applied reduced representation bisulphite sequencing compare methylation profiles between wild Nile tilapia females their...
Growth is a complex trait whose variability within population cannot be explained solely by genetic variation. Epigenetic regulation often suggested as an important factor shaping the phenotype, but its association with growth can highly context- and species-dependent. Nevertheless, mechanisms involved in epigenetic of fish are poorly understood. We have used reduced representation bisulphite sequencing to determine genome-wide CpG methylation patterns male female Nile tilapia different...
European eel (Anguilla anguilla) is a catadromous fish species that received substantial attention as its population has markedly declined in the last three decades. The possible causes of this decline include habitat fragmentation factors such dams and weirs. In some cases, these obstacles are equipped with friendly passage devices may select young eels according to their climbing behaviour. We tested how individual tendency was related event fishway experienced field classified profiles...
Selectivity of recreational angling on fish behaviour was studied by examining whether capture order or lure type (natural v. artificial bait) in ice-fishing could explain behavioural variation among perch Perca fluviatilis individuals. It also tested if individually assessed personality predicts groups, the presence natural predators. showed repeatable both individual and group tests. Capture order, method, condition factor past growth rate did not behaviour. Individually determined...
European eel is a panmictic species, whose decline has been recorded since the last 20 years. Among human-induced environmental factors of decline, impact water dams during species migration questioned. The main issue this study was to pinpoint phenotypic traits that predisposed glass eels successful passage by barriers. approach individual-centred and without any priori hypothesis on involved in putative obstacles selective pressure. We analyzed transcription level 14,913...
In vertebrates, the somatotropic axis comprising pituitary gland, liver and muscle plays a major role in myogenesis.Its output terms of growth is highly affected by nutritional environmental cues, thus likely epigenetically regulated.Hydroxymethylation emerging as DNA modification that modulates gene expression but holistic characterization hydroxymethylome has not been investigated to date.Using reduced representation 5-hydroxymethylcytosine profiling we demonstrate tissuespecific...
Fishways are built on obstacles to restore the connectivity between aquatic habitats. Our study investigated how species-specific fishways interact with interindividual trait differences among fish. We compared several groups of glass eels (Anguilla anguilla) climbing two types those remaining below water impoundments. analyzed relative body condition factor, length, mass, and in vitro activities gene transcription levels enzymes involved energy metabolism (LDH, CS, CCO, PK). Differences...
L’anguille européenne Anguilla anguilla est une espèce catadrome avec un cycle de vie complexe incluant des migrations entre la mer Sargasses, l’Europe et l’Afrique du Nord. Du fait sa baisse drastique population depuis 30 ans, l’anguille considérée aujourd’hui comme « en danger critique d’extinction ». Une causes ce déclin fragmentation l’habitat. L’hypothèse pression sélection obstacles aquatiques exercée sur les jeunes anguilles migration a été étudiée approche sans priori , où grand...
