Tolerance to total dissolved gas supersaturation in Atlantic salmon, brown trout, rainbow trout, and European minnow
Fig 21
Gill embolism and mortality rates observed in brown trout during subacute gas bubble disease.
Cumulative frequency of observed gill embolism and mortality or moribund brown trout (Salmo trutta) parr in group T110 exposed to 110% total dissolved gas supersaturation (TDG) over 14 days. Cumulative frequency of observations is expressed as a linear regression (fitted line) for gas embolism in gills (○; y = 0.0367x − 0.0867) and for mortality or moribund fish (●; y = 0.0123x − 0.0079). The respective coefficients of determination (R2) and p-values are shown in the figure.
