Effect of an acute necrotic bacterial gill infection and feed deprivation on the metabolic rate of Atlantic salmon Salmo salar
In this study, experiments were conducted to examine the effect of an acute necrotic bacterial gill infection on the metabolic rate (M O2) of Atlantic salmon Salmo salar. Fed and unfed Atlantic salmon smolts were exposed to a high concentration (5 10 12 CFU ml -1) of the bacteria Tenacibaculum marit...

Fed and unfed Atlantic salmon smolts were exposed to a high concentration (5 10 12 CFU ml -1) of the bacteria Tenacibaculum maritimum, their routine and maximum metabolic rates (M O2rout, and M O2max, respectively) were measured, and relative metabolic scope determined.

The decrease in metabolic scope was a result of significantly increased M O2rout of both fed and unfed infected salmon. Fed infected fish had a mean SEM increase in M O2rout of 1.86 0.66 M O 2 g -1 h -1, whilst unfed infected fish had a mean SEM increase of 2.16 0.72 M O 2 g -1 h -1.
