与预期相反，7至33天大的巴拉蒙迪在变态期间的觅食行为并没有从跳跃策略过渡到巡航搜索策略。相反，觅食行为发生了持续的变化，从游泳停顿到游动路径变得越来越直的时间越来越长，这意味着对游泳的水动力限制可能是觅食运动学的关键决定因素。有人建议，需要重新评估将跳跃搜索作为第三种独特的觅食策略的概念。(C)2000年不列颠群岛渔业协会。
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. (C) 2000 The Fisheries Society of the British Isles.
