The survival of smolts of salmon Salmo salar L. at low concentrations of dissolved oxygen
The survival of Atlantic salmon smolts on sudden exposure to low constant concentrations of dissolved oxygen (DO) has been measured under laboratory conditions; the 3‐d LC50 is about 3 mg l −1 in freshwater and about 2.5 mg l −1 in 30% and 80%‘sea water’, even for fish acclimated for several days to...

Summary: | The survival of Atlantic salmon smolts on sudden exposure to low constant concentrations of dissolved oxygen (DO) has been measured under laboratory conditions; the 3‐d LC50 is about 3 mg l −1 in freshwater and about 2.5 mg l −1 in 30% and 80%‘sea water’, even for fish acclimated for several days to low concentrations of DO and high salinity; median threshold concentrations of DO are probably close to 3.3 and 2.6 mg l −1 respectively. |
