Description
Summary:	Data collected from underwater video recordings in the wild and in a semi-natural channel were used to study two examples of relatively unknown behaviour in the Salmoninae subfamily - false spawning in females and digging in Oncorhynchus males. Observations suggest that false spawning should be regarded as an incomplete fixed behavioural pattern (FBP) and that male digging represents two special types of FBP (displacement FBP) with threatening and courting functions as ultimate causes.
