BACKGROUND Endocrine disruptors include plasticizers, pesticides, detergents, and pharmaceuticals. Turbot and other flatfish are used to characterize the presence of chemicals in the marine environment. Unfortunately, there are relatively few genes of turbot and other flatfish in GenBank, which limits the use of molecular tools such as microarrays and quantitative reverse-transcriptase polymera...

BACKGROUND Turbot (Scophthalmus maximus L.) is an important aquacultural resource both in Europe and Asia. However, there is little information on gene sequences available in public databases. Currently, one of the main problems affecting the culture of this flatfish is mortality due to several pathogens, especially viral diseases which are not treatable. In order to identify new genes involved...

the spanish turbot aquaculture sector holds a top position in the international market. thisactivity is mainly developed along the galician coast (nw spain). this article evaluates the environmentalperformance of galician turbot aquaculture according to the life cycle assessment (lca) methodology.previously, on account of the expected relevance of feed for aquaculture, marine aquafeed productio...

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...

A number of viral haemorrhagic septicaemia (VHS) virus isolates of European marine origin were shown to be of low pathogenicity or non-pathogenic to Atlantic salmon parr by water-borne infection. A reference freshwater VHS virus isolate known to be highly pathogenic to rainbow trout was also of low pathogenicity to Atlantic salmon. Virus was detected in some mortalities, however, demonstrating ...

A comparative analysis of the microbiological quality of three turbot (Scophthalnus maximus) farms (A, B, and C) located in Galicia (northwest Spain) is given. The microbial load and types of bacteria in the internal organs (liver and kidney) of apparently healthy fish was monitored over a year, and all the disease problems occurring during this survey were analyzed. The percentage of healthy t...

Serolog~cal and molecular properties of 2 birnavlruses Isolated from Norwegian turbot Scophthalmus rnaxlmus were examined. The viral RNA and polypept~des patterns, as well as neutral~zation test results, showed that these stralns were closely related to infectious pancreat~c necrosls vlrus, serotype VR-299. Infectivity trials indicated no pathogenic~ty for turbot. This is the first isolation in...

Edwardsiella tarda is an enterobacterial fish pathogen that causes mortality in various fish species worldwide. In this study, we analyzed the intraspecific variability in a collection of E. tarda strains isolated from turbot. To do this we employed 4 polymerase chain reaction (PCR)-based methods: (1) random amplified polymorphic DNA (RAPD), (2) enterobacterial repetitive intergenic consensus-P...

Résumé Characteristics of Lactic Acid Bacteria (LAB) isolated from rotifers, ~rachionus plicutilis, resembled those of Lactobacillus plantarum or Carnobacteriurn sp. It was investigated whether the artificial maintenance of a high concentration of LAB in rotifers might increase their dietary value for turbot larvae, particularly when the fish were infected with pathogenic Vibrio sp. One LAB str...
