Abstract In Europe, turbot aquaculture has a high potential for sustainable production, but the low tolerance to fishmeal replacement in diet represents big issue. Therefore, this study investigated effects of more feed formulations on growth and performance, as well nutritional status juvenile recirculating systems. 16-week feeding trial with 20 g turbot, one control containing traditional fis...

Fish otoliths provide a record of age, growth, and environmental influences. In both trout and turbot, spatial chemical investigation of the endolymph surrounding the otolith (sagitta) showed a lack of uniformity. Proteins, [Formula: see text], and Mg2+ were significantly more concentrated in the proximal (facing the macula) than distal zone, whereas the opposite was observed for K+ and total C...

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...

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 ...

Florida. He is the co-editor of Anarchy and the Environment: The International Relations of Common-Pool Resources, and has also worked on issues of sovereignty and international economic leadership. Abstract While the " Turbot War " between Canada and Spain is an instance of violent conflict over an increasingly scarce resource, it represents a departure from traditional environmental conflict ...

Expression of polymorphic myofibrillar and sarcoplasmic proteins was investigated in the fish Scophthalmus maximus (L.) undergoing metamorphosis. A range of electrophoretic techniques was used to monitor sequential synthesis of isoforms from hatching to the adult stage. Two isoforms (larval and adult) of myosin light chain LC2 and troponin-I were successively detected during turbot growth, in a...

Tenacibaculum maritimum is the etiological agent of marine flexibacteriosis disease, with the potential to cause severe mortalities in various cultured marine fishes. The development of effective preventive measures (i.e. vaccination) requires biochemical, serological and genetic knowledge of the pathogen. With this aim, the biochemical and antigenic characteristics of T. maritimum strains isol...
