Tolerance to total dissolved gas supersaturation in Atlantic salmon, brown trout, rainbow trout, and European minnow
Fig 14
Cumulative frequencies of observed subcutaneous emphysema in Atlantic salmon (Salmo salar) fry.
Occurrence of gas bubbles in operculum, buccal cavity, and head region of fry exposed to 110% (n = 30), 115% (n = 30) and 120% (n = 30) total dissolved gas. Gas bubbles on the head region were only observed in fry exposed to 120% total dissolved gas (TDG) supersaturation.
