On sandy beach nursery grounds along the west coast of Ireland, 0 year-group turbot Scophthalmus maximus were found to consume six types of crustaceans, in addition to polychaetes. The 0 year-group brill Scophthalmus rhombus fed almost exclusively on mysids, even though nine taxonomic prey groups were identified in the sediment across the investigated beaches. Both species avoided non-motile or...
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...
Amoebic gill disease of turbot Scophthalmus maximus L. associated with mortalities was repeatedly diagnosed at culture facilities in NW Spain. The agent was assigned to the genus Paramoeba Schaudin, 1896. Trophozoites found in the gill tissue as well as those cultured displayed most of the principal characteristics of P. pemaquidensis Page, 1970. The identity with P. pemaquidensis, known as an ...
A new group of Cytophaga-like bacteria has been recovered from healthy and diseased turbot in Scotland. Cultures produced orange colonies and contained short rods with distinctively thick cell walls. Gliding movement was observed and the guanine plus cytosine ratio of the DNA was 31.7 to 32.1 mols %. The organism caused gill hyperplasia and systemic haemorrhagic septicaemia in both naturally di...
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, ...
The present article reports the effect on survival as well as on the morpho-histochemical changes in the trunk kidney of juvenile turbot Scophthalmus maximus, L. induced by acute action of the anionic surfactant, sodium dodecyl sulphate (SDS). The LC50 of SDS at 96 hours was found to be 7.5 mg/l. Lots of 20 juvenile turbots were exposed to SDS concentrations of 3, 5, 7 and 10 mg/l: the exposure...
BACKGROUND The turbot (Scophthalmus maximus; Scophthalmidae; Pleuronectiformes) is a flatfish species of great relevance for marine aquaculture in Europe. In contrast to other cultured flatfish, very few genomic resources are available in this species. Aeromonas salmonicida and Philasterides dicentrarchi are two pathogens that affect turbot culture causing serious economic losses to the turbot ...
Turbot (Scophthalmus maximus) is a very valuable fish species both in Europe and China. The culture of this flatfish is well-established but several bacteria, viruses, and parasites can produce mortality or morbidity episodes in turbot farms. Viral Hemorrhagic Septicemia Virus (VHSV) is one of the most threatening pathogens affecting turbot, because neither vaccines nor treatments are commercia...
