Electric fields (EFs) are widely used in human activities, and all organisms are potentially affected by EFs. The effects of an EF on terrestrial plants, seeds and water animals are well documented, whereas the effects of an EF on aquatic macrophytes remain unknown. We wanted to determine the effects of an EF, generated by backpack electrofishing equipment, on the growth and metabolism of three submerged plants (Vallisneria natans, Myriophyllum spicatum and Potamogeton maackianus). The results showed that the shoot heights, shoot dry weights, root dry weights, root : shoot ratios and contents of soluble proteins and soluble carbohydrates of the three tested submerged plants were influenced by the EF, and these effects were significantly different among the study plants. Thus, our results indicated that submerged macrophytes might be suppressed by EFs released by electrofishing. Accordingly, we highlight that the growth, development and metabolism of submerged macrophytes might be inhibited by EFs, although the results were obtained from a simulated experiment, and more extensive field experiments are needed.

电捕鱼对三种水下大型植物的生长和代谢构成潜在威胁

电场 (EFs) 广泛用于人类活动，所有生物都可能受到 EFs 的影响。EF 对陆生植物、种子和水生动物的影响已有详细记录，而 EF 对水生大型植物的影响仍然未知。我们想确定由背包式电捕鱼设备产生的 EF 对三种沉水植物（Vallisneria natans、Myriophyllum spicatum 和 Potamogeton maackianus）生长和代谢的影响。结果表明，三种受试沉水植物的茎高、茎干重、根干重、根：茎比以及可溶性蛋白质和可溶性碳水化合物的含量均受EF的影响，并且这些影响在研究植物之间存在显着差异。 . 因此，我们的结果表明，沉水大型植物可能会被电捕鱼释放的 EFs 抑制。因此，我们强调沉水植物的生长、发育和代谢可能会被 EFs 抑制，尽管结果是从模拟实验中获得的，并且需要更广泛的现场实验。
