Development of a homologous radioimmunoassay for a gonadotropin of the gilthead seabream, Sparus aurata [PDF]
A glycoproteic gonadotropin (GtH) was partially isolated from pituitaries of sexually mature Sparus aurata and used for the development of its radioimmunoassay (RIA). Two major chromatographic steps were used for the isolation of the GtH: affinity chromatography on Concanavalin A-Sepharose and gel filtration on Ultrogel ACA-54.

Bacterial community in response to packaging conditions in farmed gilthead seabream
The objective of this study was to evaluate the effect of modified atmosphere packaging (MAP) on fish skin, gills and intestines bacterial microbiome.Whole gilthead seabream was packed aerobically or under modified atmospheres (60% CO2, 30% N2, 10% O2) and stored isothermally at 0 °C.

Variability of key-performance-indicators in commercial gilthead seabream hatcheries
AbstractSkeletal abnormalities are one of the most important key-performance-indicators (KPIs) in finfish hatcheries. Coping with the problem of skeletal abnormalities relies on the understanding of the link between the variability in the rearing conditions, and the variability in abnormalities incidence. Here, 74 seabream larval populations, from four

Organic anthropogenic compounds such as polycyclic aromatic hydrocarbons, polychlorinated biphenyls, nitroaromatics, dioxins, various pesticides and natural compounds can enter the aquatic environment. These lipophilic compounds are readily taken up into

The supplementation of fish diets with OH-SeMet reduces oxidative stress and modulates immune response against bacterial infection. However, despite the importance of essential polyunsaturated fatty acids in fish nutrition and their high risk of ...

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

ABSTRACT Cell lines are essential tools for studying animal physiology and immunopathology, reducing the use of live animals and supporting the 3Rs principle of reduction, refinement, and replacement. The Senegalese sole (Solea senegalensis), a relevant species for Spanish aquaculture diversification, lacks established in vitro models. We developed SsB‐

ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.

GABA receptors in the olfactory epithelium of the gilthead seabream (Sparus aurata)
ABSTRACT Exposure to high PCO2/low pH seawater induces behavioural alterations in fish; a possible explanation for this is a reversal of Cl−/HCO3− currents through GABAA receptors (the GABAA receptor theory). However, the main evidence for this is that gabazine, a GABAA receptor antagonist, reverses these effects when applied to the ...
