| Abstract: | 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. |
