An important feature of the behaviour of salmon is the
leaping and rolling activity. These surface activities were
studied in fish in net pens in relation to environmental
factors and operational procedures. Data were collected
manually and automatically by different sensors.
Daily changes of surface activity were observed. Effects of
stressors were also demonstrated. The importance of surfacing
in salmon fish farming is discussed.
