Fig. 5From: In situ measurement of salinity during seaward migration of Atlantic salmon post-smolts using acoustic transmitters with data-storage capabilities and conventional acoustic transmittersTypical outward movement patterns of tagged fish with recordings of ambient salinity. Open circles indicate the detection at sites 1–6. Open squares indicate the salinity range in a 2.25-h period during the outward movement. Salinity-range values used in the figure are average values. For example, salinity data from salinity-range value 2 (8.0–11.9 psu) are shown as 10.0 psuBack to article page
