Foraging kinematics of barramundi during early stages of development

Contrary to expectations there was no transition from a saltatory to a cruise search strategy in foraging behaviour of 7- to 33-day-old barramundi over the period of metamorphosis. Rather, there was a continual change in foraging behaviour, with increasing durations between swimming pauses and increasingly straight swimming paths, implying that hydrodynamic constraints on swimming may be a key determinant of foraging kinematics. It is suggested that the notion of saltatory search as a third, unique foraging strategy needs to be re-evaluated.
