    Notes: Abstract. The first outbreak of bacterial kidney disease in farmed salmonids in Scotland was recorded in 1976, The number of individual outbreaks has now risen to at least 37. Disease outbreaks are seasonal, reaching a peak during May. In many cases infection has spread following the movement of juvenile fish. Mortalities are variable; in extreme cases 20% per annum occurs. Both gross signs and mortalities are reduced in fish reared in sea water.

    On remembrance of the abdominal pores in rainbow trout, Salmo gairdneri Richardson, and some other salmonid spp. (1982)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Direct connections (abdominal pores) between the peritoneal cavity and the external environment of elasmobranch fishes and some teleost species including the Salmonidae were recognized almost 100 years ago but over this period their existence in these teleost species has been omitted from anatomical texts. In this report, the abdominal pores of rainbow trout, Salmo gairdneri, Atlantic salmon, Salmo salar, and the cisco, Coregonus artedii, were examined in relationship to ip injected particulate material. Both carbon particles and suspensions of the bacterial kidney disease organism were found to be extruded within masses of macrophages and as free particles through the abdominal pores in fish injected ip 72 h previously. The pores were patent in male and female, mature and immature fish. The role and significance of the abdominal pores in rainbow trout in the clearance from the body of material, including material likely to be used for vaccinating fish, is discussed.

    Notes: Seven (0.039%) and five (0·028%) of 18 163 common dab from the east coast of Scotland were definitive hosts to Lernaeocera branchialis and to Haemobaphes cyclopterina, respectively. Both represent new host records. Muscle necrosis and localized haemorrhage were associated with H. cyclopterina infestation and as described from other definitive hosts.

    Serum agglutinating titres against Renibacterium salmoninarum the causative agent of bacterial kidney disease, in rainbow trout, Salmo gairdneri Richardson, and Atlantic salmon, Salmo salar L. (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 30 (1987), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Serum agglutinating titres against Renibacterium salmoninarum were determined from clinically infected, sub-clinically infected and non-infected rainbow trout, Salmo gairdneri Richardson, and Atlantic salmon, Salmo salar L. Titres ≥16 occurred in clinically infected rainbow trout, but declined after a few months when disease signs were absent. Non-infected rainbow trout had titres ≤ 16. No correlation between the agglutinating titre and the level of infection was found in farmed Atlantic salmon. Variable titres were found in wild salmon broodstock although there was no evidence of BKD during 4 years of testing.

    Non-specific cellular responses of rainbow trout to Vibrio anguillarum and its extracellular products (ECPs) (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 45 (1994), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: We have studied the early inflammatory response induced by Vibrio anguillarum and by its extracellular products (ECPs) in rainbow trout after intraperitoneal injection. The results showed a very similar inflammatory response which included leucopenia, mainly due to lymphopenia, neutrophilia and an increase in the number of circulating monocytes. Melanomacrophages as well as immature leucocytes were frequently observed circulating in the blood of injected rainbow trout. Monocytes often contain phagocytosed bacteria and other, altered cells including erythrocytes and leucocytes. However, neutrophils only occasionally phagocytosed bacteria. Many circulating leucocytes showed important structural alterations. Neutrophils of trout injected with bacteria and ECPs also showed stronger PAS-staining than those of control trout as well as Döhle bodies and swollen granules. A marked vasodilatation was observed in the kidney and spleen which was coincidental with a mobilization of eosinophilic granular cells and an hypertrophy of sinusoidal endothelial cells showing an increase in the number of cytoplasmic granules. An increase in the number of macrophages and melanomacrophages in the kidney and spleen as well as oedema and leucocyte infiltration in the liver and gills were also noted.

    Cranial nodules in farmed Atlantic salmon, Salmo salar L., fry (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of applied ichthyology 13 (1997), S. 0

    Notes: Cranial nodules are described from Atlantic salmon, Salmo salar fry hatched from certain egg batches. Conspicuous, smooth, mostly unilateral nodules were recorded on the cranium. Histologically, the cerebellum appeared normal, but was displaced dorsally. Karyorhectic malpighian cells were absent from the epidermis and the meninges appeared normal. There was no apparent contact of the cerebellum with the water, or evidence of fungal, bacterial or parasitic infection. Mortality of up to 15% as recorded. The aetiology of this condition is currently unknown.

    The potential of carbaryl as a treatment for sea lice infestations of farmed Atlantic salmon, Salmo salar L. (1990)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The treatment of sea lice, Lepeophtheirus salmonis infestations on farmed Atlantic salmon, Salmo salar requires regular bathing of the fish in diachlorvos (DDVP), 2,2-dichlorovinyl dimethyl phosphate, with subsequent release to the marine environment of spent pesticide. The toxicity of a possible alternative compound, carbaryl, l-naphthyl N-methylcarbamate) to kill sea lice and Atlantic salmon was examined. Preliminary studies with carbaryl indicate the potential advantage of a reduced treatment dose was outweighed by the greater persistence of both the parent compound and of its toxic degradation product. Hence this carbamate insecticide is unlikely to be considered by regulatory authorities as an alternative treatment for sea lice infestations.

    Multiple lipoma in the common dab, Limanda limanda L. (1991)

    Notes: From data gathered during disease monitoring surveys in the North Sea during 1989 and 1990, a previously undescribed lipoma of common dab (Limanda limanda) is reported. Single, and multifocal circular, yellow lesions on the ventral surface were indicative of this hypodermal lipoma which predominated in mature female dab. No positive correlation could be found between the lipoma and the practice of sewage sludge dumping or oil field activities. The etioiogy of this tumour is unknown.〈section xml:id="abs1-2"〉〈title type="main"〉Résumé Le lipomne multiple chez la Limande Commune, Limanda limanda L.Sur la base de données recueillies au cours des contröles de morbidité effectués pendant 1989 et 1990 dans la mer du Nord on a pu signaler chez la limande commune (Limanda limanda) un lipome qui n'avait pas été note antérieurement. Ce lipome hypodermíque, plus répandu chez les femelles müres, se caractérisait par des lesions jaunes, ou bien individuelles ou bien circulaires et multifocales, affectant la surface ventrale. Aucune corrélation positive n'a étéétablie entre le lipome et la décharge de vidanges ou les activités de l'industrie pétrohére. On ignore l'étiologie de cette tumeur.〈section xml:id="abs1-3"〉〈title type="main"〉Zusammenfassung Multiple Lipome der Kliesche (Limanda limanda L.)Ein bislang nicht beschriebenes Lipom der Kliesche (Limanda limanda) wird anhand von Daten der bestandskundlichen Untersuchungen auf Krankheiten der Jahre 1989 und 1990 beschrieben. Einzelne oder multifocale kugelförmige gelbliche Läsionen der ventralen Körperoberfläche waren die vorherrschenden Symptome für diese hypodermalen Lipome, die vornehmlich bei weiblichen Klieschen auftraten. Eine positive Korrelation zwischen dem Auftreten der Lipome und der Verklappung von Klärschlamm oder Aktivitäten auf den Olfeldern wurde nicht gefunden. Die Etiologie dieser Tumoren ist unbekannt.
