Disease resistance in Atlantic salmon (Salmo salar) selected for high or low responses to stress

Coho salmon Oncorhynchus kisutch strain differences in disease resistance and non-specific immunity, following immersion challenges with Vibrio anguillarum

“…Fevolden et al (1991) found that Atlantic salmon Salmo salar from a high stress line had increased plasma glucose concentration and lysozyme activity, supporting the hypothesis that more easily stressed fish are less disease resistant. This hypothesis was further supported following later disease challenge experiments (Fevolden et al 1993) that revealed that the high stress line were indeed less resistant to the disease furunculosis and had significantly lower non-specific immunity as measured by hemolytic activity.…”

The effect of temperature on non-specific defence parameters of three strains of juvenile Atlantic halibut (Hippoglossus hippoglossus L.)

“…Variation in immune response and susceptibility to disease between species and strains have been reported [12,15,[34][35][36] but there is no evidence within the literature of how non-specific immune responses vary between strains of Atlantic halibut. Temperature influenced some haematological parameters in this study, as evidenced by PCV, percentage leucocyte population and di#erential leucocyte counts.…”

Rainbow trout offspring with different resistance to viral haemorrhagic septicaemia

“…In salmonids, variation in resistance towards specific pathogens has received particular attention (Gjedrem et al, 1991;Beacham & Evelyn, 1992;Fevolden et al, 1992Fevolden et al, , 1993Ibarra et al, 1992;Okamoto et al, 1993). The use of immunological parameters for indirect selection for disease resistance was suggested by Fjalestad et al (1993).…”
