在日本中部的22个池塘中，对引进的捕食-被捕食配对——大口黑鲈和蓝鳃鱼对远洋生产力的影响进行了实证研究。在单变量分析中，鱼类入侵对叶绿素浓度的影响并不明显，这主要是因为这种影响分别被磷有效性的正效应和池塘面积的负效应所屏蔽。以养分有效性和池塘面积为独立因子的最佳统计模型对叶绿素浓度有正影响。鱼类入侵降低了甲壳类动物相对于轮虫的生物量。研究表明，这些外来鱼类的入侵影响了池塘中上层生物群落。
An empirical study was conducted on the effects of an introduced predator–prey pair, largemouth bass and bluegill, on pelagic productivity in 22 ponds in central Japan. In the univariate analysis, the effect of fish invasion on chlorophyll concentration was not evident, primarily because this effect was screened by the positive and negative effects of phosphorus availability and the pond area, respectively. A positive effect on chlorophyll concentration was detected in the best statistical model using nutrient availability and pond area as independent factors. Fish invasion decreased the relative biomass of crustaceans to rotifers. This study showed that the invasion of these exotic fishes affected the pelagic community in the pond.
