ResumoAtlantic salmon Salmo salar presmolts were intrapentoneally injected with a n organ homogenate from individuals of the same species suffering from a n acute outbreak of infectious salmon anaemia (ISA).Mortality started in the infected group 18 d after inlection.Blood samples from the diseased group showed that these fish had elevated plasma cortisol levels compared w t h control fish.The cortisol level was correlated to the seventy of the anaemia condition, as represented by haematocrit values.Plasma lactate levels were also elevated in diseased flsh, but there was a greater variability in the level of this parameter.
