With the aim of elucidating the causes of the high mortality of turbot (Scophthalmus maximus L.) larvae during development, histopathological studies were carried out and the role of the swimbladder in turbot larval pathology was investigated. Several batches of 1 to 90-d-old larvae from a commercial hatchery were sampled during the course of 3 years. Alterations were observed in swimbladders m...

With this purpose in mind, an ozone generator device was coupled to a slurry ice system working subzero at -1.5oC. The ozone concentration was adjusted to a ...

This paper describes the development of a high density consensus genetic linkage map of a turbot (Scophthalmus maximus L.) family composed of 149 mapping individuals using Single Nucleotide Polymorphisms (SNP) developed using the restriction-site associated DNA (RAD) sequencing technique with the restriction enzyme, PstI. A total of 6,647 SNPs were assigned to 22 linkage groups, which is equal ...

Background: Edwardsiella tarda, the etiologic agent of edwardsiellosis, is a devastating fish pathogen prevailing in worldwide aquaculture industries and accounting for severe economic losses. There is a raising concern about E. tarda being a significant zoonotic pathogen, and it is urgent to develop a rapid detection of this pathogen. This is the first study to develop a test strip for rapid d...

The development of feeding hierarchies was investigated in juvenile turbot, Scophthalmus Ž . maximus Rafinesque held at two rearing densities for 82 days. Individual biometrics were measured on five occasions and a diet labelled with ballotini glass beads was used in combination with a noninvasive radiographic technique to estimate consumption rates. The results demonstrate that the inclusion o...

One quorum sensing strain was isolated from spoiled turbot. The species was determined by 16S rRNA gene analysis and classical tests, named Aeromonas sobria AS7. Quorum-sensing (QS) signals (N-acyl homoserine lactones (AHLs)) were detected by report strains and their structures were further determined by GC-MS. The activity changes of AHLs on strain growth stage as well as the influence of diff...

1. Five groups of juvenile turbot (Scophthalmus maximus) which had been given a diet free of fat for 12 weeks were given diets in which the lipid component (g/kg) was: oleic acid alone 50, oleic acid 40+linoleic acid 10, oleic acid 40+linolenic acid 10, oleic acid40+arachidonic acid 10 or oleic acid 40+cod-liver oil 10. These five experimental diets were given for 16 weeks. 2. Weight gains were...

Estuaries are complex environments that provide important nursery areas for several fish species, but anthropogenic activities as well low salinities may affect reproductive potential. This study investigated spawning migrations of turbot (Scophthalmus maximus) and European flounder (Platichthys flesus) in the estuary Roskilde Fjord using acoustic telemetry. For turbot, migratory behaviour was ...

Abstract Objectives Parvalbumin (PV) is the primary allergen found in fish and highly conserved. According to some studies, patients with allergy are allergic only one species of but tolerant others; however, underlying mechanism has not been identified. Materials Methods The cross-reactivity these seven parvalbumins based on turbot PV-treated mice was determined using BALB/c mouse RBL-2H3 cell...

The aim of this study was to compare the organismal responses farmed and wild-caught turbot, Scophthalmus maximus, based on analyses biochemical plasma parameters, leukocyte profile, histological tissue profile gills, kidney, liver, intestine, spleen, as well gene expression stress proteins in kidney liver tissue. results revealed significant differences triglycerides (TRIG), total protein (TP)...
