1. 许多关于河流鱼类活动的研究发现，大多数个体是久坐不动的，活动范围非常有限。最近，这种“受限运动范式”受到了挑战，目前有必要对家庭范围概念进行测试，作为描述河流鱼类运动的理论基础。在这篇论文中，我描述了对澳大利亚布罗克河的金鲈鱼（Macquaria ambigua）和鲤鱼（Cyprinus carpio）的无线电跟踪研究，旨在评估作为描述这些物种运动的一种手段的家庭范围概念。通过随机运动分析和易位实验来测试场地保真度和家庭范围占用。金鲈鱼和鲤鱼都表现出较强的场地保真度，并占据有限的家园范围。鲤鱼的总栖地范围比金鲈大，两者在栖地范围内都有集中利用区（核心区）。在研究期间，一些金鲈鱼和鲤鱼在它们的活动范围的位置上表现出了变化。为了将这种转移纳入理论框架，提出了“家园范围转移”概念模型，并讨论了在描述家园范围移动时考虑场地保真度的时间稳定性的必要性。
1. Many studies of the movements of riverine fish have found that most individuals are sedentary and occupy very restricted home ranges. Recently, this 'Restricted Movement Paradigm' has been challenged and there is currently a need for tests of the home range concept as a theoretical basis for describing the movements of riverine fish. In this paper, I describe a radio-tracking study of golden perch (Macquaria ambigua) and carp (Cyprinus carpio) in the Broken River, Australia that aims to assess the home range concept as a means of describing the movements of these species.2. A random movement analysis and a translocation experiment were conducted to test for site fidelity and home range occupation. Both golden perch and carp exhibited strong site fidelity and occupied restricted home ranges. Carp had larger total home ranges than golden perch, and both species had areas of concentrated use (core areas) within the home range.3. Several golden perch and carp exhibited shifts in the locations of their home ranges during the study. To incorporate such shifts into a theoretical framework, a 'home range shift' conceptual model is proposed and the need to consider the temporal stability of site fidelity when describing home range movements is discussed.
