活性叶绿素荧光在水生研究中的主要用途之一是检查初级生产力，而不受“传统”基于气体交换的测量方法的限制。荧光可以直接在原位测量，而不需要孵育分离的样品，这些样品已经从自然固有的环境变异性中去除（Kolber和Falkowski 1993）。此外，荧光测定法提供的高数据收集率允许研究生产力与物理强迫的耦合，从而检查可能对水生系统的功能响应产生不成比例影响的瞬态现象（Kolber等人，1990；Falkowski等人，1991；Moore等人，2003）。尽管有这些优点，基于荧光的生产力应用在某种程度上需要相当长的时间才能在传统的水生采样学科中牢固建立起来。
One of the major uses of active chlorophyll fluorescence in aquatic studies has been to examine primary productivity free from constraints associated with ‘conventional’ gas exchange-based measurements. Fluorescence can be measured directly in situ and without the need to incubate discrete samples that have been removed from natural inherent environmental variability (Kolber and Falkowski 1993). Additionally, the high rate of data collection afforded by fluorometry allows investigations of the coupling of productivity to physical forcing and hence the examination of transient phenomena that can have a disproportionate impact on the functional response of aquatic systems (Kolber et al. 1990; Falkowski et al. 1991; Moore et al. 2003). In spite of these advantages, fluorescence-based productivity applications have, to some extent, taken a considerable time to become firmly established within conventional aquatic sampling disciplines.
