Non-invasive blood glucose level (BGL) evaluation technology in skin mucus is a wearable stress-detection means to indicate the health status of live fish for compensating drawbacks using traditional invasive biochemical inspection. Nevertheless, commonly used methods cannot accurately obtain BGL variations owing influence an uncertain exudation rate, ambient effects, and individualized differe...

Turbot is one of the most important farmed fish in Europe. This species exhibits a considerable sexual dimorphism in growth and sexual maturity that makes the all-female production recommended for turbot farming. Our knowledge about the genetic basis of sex determination and the molecular regulation of gonad differentiation in this species is still limited. Our goal was to identify and compare ...

Growth in developing turbot larvae can be expressed independently of temperature when using effective day-degrees (D8 ) as an index of development. The calculation of D8 is based on the eff eff principle of thermal summation whereby the rate of development is linearly related to the ambient temperature above a species-specific threshold temperature (T ) at which development is 0 theoretically a...

Industrial incidents can result in radionuclide release in the environment, among which (110m)Ag. Indeed, under particular circumstances, non-negligible amounts of (110m)Ag have been measured in the marine environment (as observed in Fukushima Dai-ichi incident). This element can therefore be accumulated by aquatic organisms through different pathways including the trophic transfer. The present...

Nodaviruses are the etiological agents of one of the most serious viral diseases affecting marine fish aquaculture. Nodavirus infection produces an abnormal swimming behaviour and causes encephalopathy and retinopathy associated to important mortalities. The expression of TNF-alpha, IRF-1 and Mx was increased in turbot after nodavirus infection. A significant increase in the production of nitro...

Pseudomonas fluorescens is a Gram-negative bacterium and a common pathogen to a wide range of farmed fish. In a previous study, we found that the ferric uptake regulator gene (fur) is essential to the infectivity of a pathogenic fish isolate of P. fluorescens (wild-type strain TSS). In the present work, we conducted comparative proteomic analysis to examine the global protein profiles of TSS an...
