Turbot - Scophthalmus maximus
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...
متن کاملSwimbladder pathology during larval development of turbot ( , Scophthalmus maximus L . )
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...
متن کاملSystemic disease in turbot Scophthalmus maximus
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...
متن کاملProtein digestion in juvenile turbot Scophthalmus / maximus and effects of dietary administration of Vibrio proteolyticus
The trial was made to study the protein digestion in juvenile turbot during passage of digesta from stomach to rectum. Moreover, diet supplementation with the potential probiotic bacteria, Vibrio proteolyticus, was evaluated with regard to protein digestion. For a 3-week period, fish Ž . 25–30 g were fed by oral intubation and received either a liquid mixture consisting of 40% nonpurified contr...
متن کاملEpizoic amoebae from the gills of turbot Scophthalmus maximus.
Species of amoebae belonging to the genera Platyamoeba Page, 1969, Vannella Bovee, 1965 and Flabellula Schaeffer, 1926 were found to accompany Paramoeba sp., the agent of amoebic gill disease (AGD), in clinically diseased turbots. The same community of epizoic gymnamoebae was found on the gills of turbots which revealed no gill abnormalities but slight behavioral signs indicative of suboptimal ...
