几乎每一个生物遥测术研究的一个假设是,标记的动物代表未加标签的人口。的过程,研究动物捕获,处理,和标签,以及携带发射机的行为,将会对他们的行为和性能的影响很小。这样的假设,通常表示为缺乏发射机效果,必须有效如果遥测研究描述准确的动作和行为整个人口的利益,而不是只有一个子集的人口。

考虑到必要的事件序列实现遥测技术研究(即。,collection, handling, transmitter attachment), as well as the intrusive nature of many transmitter attachment techniques, it is likely that there will be some effect on the study animals. These potential impacts can range from mild to severe, from transitory to permanent, and may be manifest immediately or not for several days to weeks after tagging.

直接物理影响可以包括压力升高,受伤,甚至死亡(骑士和Lasee 1996;Jepsen et al . 2001;Lacroix et al . 2004年)。中断的完整性尺度、粘液或皮肤可以将鱼增加感染的风险(蜜剂和海恩斯1985;万et al . 1999;鲍尔et al . 2005;危害2005)。对鱼的影响行为包括改变浮力补偿能力(Gallepp和Magnuson 1972;油炸et al . 1976年),减少游泳性能(McCleave和str 1975;康汉和霜1999; Makiguchi and Ueda 2009), reduced feeding, or changes in dominance status (Greenstreet and Morgan 1989; Armstrong and Rawlings 1993; Welch et al. 2007). Changes in behavior such as these can affect a fish’s growth, rate of maturation or migration, or increase its vulnerability to predation. At some level, these transmitter effects will be present in nearly every study using telemetry and if substantial, they can violate the critical assumption that tagged fish are representative of the untagged population.
