Treated wastewater effluent containing endocrine-disrupting chemicals is discharged into the coastal waters of the Southern California Bight (SCB) daily. The present study investigated changes in indicators of reproductive health and environmental estrogen exposure in hornyhead turbot (Pleuronichthys verticalis) near wastewater outfalls. Fish were collected from discharge areas, farfield statio...

A consensus microsatellite-based linkage map of the turbot (Scophthalmus maximus) was constructed from two unrelated families. The mapping panel was derived from a gynogenetic family of 96 haploid embryos and a biparental diploid family of 85 full-sib progeny with known linkage phase. A total of 242 microsatellites were mapped in 26 linkage groups, six markers remaining unlinked. The consensus ...

Edwardsiella tarda is an important emergent pathogen in European aquaculture, causing several mortality events in turbot Scophthalmus maximus cultures in recent years. Here, we evaluated in parallel the specificity of 4 previously published pairs of primers, gyrBF1/gyrBR1, tardaF/ tardaR, etfA and etfD, for the detection of 53 E. tarda strains isolated from different sources, as well as 18 repr...

Juvenile turbot Scophthalmus maximus that became sick during an outbreak of disease at mariculture facilities at Go-Chang, Korea, in 2003, were examined to identify the cause of the disease. The fish had pale body color, an enlarged abdomen, protruding eyes, an enlarged spleen and kidney, and pale gills and/or liver. Histopathogical examination revealed basophilic enlarged cells in the kidney, ...

Distribution Th e turbot, Scophthalmus maximus, also called Psetta maxima (Scophthalmidae, Pleuronectiformes), is naturally distributed in European waters, from Northeast Atlantic to the Arctic Circle (30o to 70oN; 23oW42oE). It occurs in the Baltic and in the Mediterranean, as well as in the Black Sea, where a subspecies Psetta maxima maeotica has been described (1). It also exists in the Sout...

This study aims to examine the nutritional composition (amino acid and fatty acid) fillet color of commercially produced cultured fish Black Sea. All species [(sea bass (Dicentrarchus labrax), sea bream (Sparus aurata), turbot (Scophthalmus maximus), large rainbow trout (Oncorhynchus mykiss)] were collected from Sea’s aquaculture sites in 2020. Total amino values fillets listed as bream>...

Growth traits represent a main goal in aquaculture breeding programs and may be related to adaptive variation in wild fisheries. Integrating quantitative trait loci (QTL) mapping and next generation sequencing can greatly help to identify variation in candidate genes, which can result in marker-assisted selection and better genetic structure information. Turbot is a commercially important flatf...

Hormonal changes, substrate mobilization and energy metabolism were studied in turbot Scophthalmus maximus exposed to 3 hypoxic conditions (oxygen partial pressure in water, PwO2 = 90, 60 and 30 mm Hg) followed by recovery under normoxia. Measurements of the blood pH, total CO2 concentration, arterial oxygen partial pressure, hematocrit, glucose, lactate, and ‘stress’ hormones (cortisol, adrena...

Hepcidins are antimicrobial peptides with an important role in the host innate immunity. Moreover, it has been reported that mammalian hepcidins present a dual-function being a key regulator in the iron homeostasis. Here, we describe the coding sequence of a novel hepcidin-like peptide in turbot, Scophthalmus maximus. This molecule presents several differences with regard to the previously char...

In aquaculture, several criteria should be considered to select an appropriate probiotic, including the aquatic origin and safety of the strain and its ability to modulate the host immune response. The properties and effects of probiotics are strain-specific and some factors such as viability, dose and duration of diet supplementation may regulate their immunomodulatory activities. In this stud...
