Numerous studies have revealed that artificial light at night alters the natural patterns of light in space and time and may have various ecological impacts at different ecological levels. However, only a few studies have assessed its effect on interactions between organisms in aquatic environments, including predator-prey interactions in lakes. To fill this gap, we performed a preliminary enclosure experiment in which we compared the foraging effect of juvenile perch () on a natural lake zooplankton community in the absence and presence of light of high-pressure sodium (HPS) lamps mimicking artificial light emitted by a boat. The results revealed that even short-lasting exposure to HPS lamps may result in increasing fish predation, which in turn decreased the mean body size in zooplankton populations (e.g. ) and affected the relative proportion between different taxa in zooplankton communities.
众多研究表明，夜间人造光改变了光在空间和时间上的自然模式，并且可能在不同生态层面产生各种生态影响。然而，只有少数研究评估了其对水生环境中生物间相互作用的影响，包括湖泊中的捕食者 - 猎物相互作用。为填补这一空白，我们进行了一项初步围隔实验，在实验中我们比较了幼鲈（）在模拟船只发出的人造光的高压钠（HPS）灯存在和不存在的情况下，对天然湖泊浮游动物群落的捕食效果。结果表明，即使是短暂暴露于HPS灯下也可能导致鱼类捕食增加，这反过来又降低了浮游动物种群的平均体型（例如），并影响了浮游动物群落中不同分类群之间的相对比例。
