The use of artificial water bodies for angling is a popular practice, especially in industrial and urbanised areas where natural water bodies are lost. In this study, the zooplankton structure dynamics and water quality at three strip mine drainage system reservoirs were assessed with different types of recreational fishery exploitation: K1—intensive angling using the catch‐and‐release model, K2—lowest angling pressure and higher share of predatory fishes and K3—moderate fishing, that is limiting groundbait quantities and eliminating non‐predatory fishes by anglers. The null hypothesis tested was that recreational fishing does not affect the biotic and abiotic conditions of reservoirs. The significance of each environmental variable was tested using redundancy analysis (RDA). The highest nutrients and chlorophyll a concentration, turbidity level and organic matter content occurred in K1. Zooplankton diversity was the lowest under these conditions; protozoa and larval stages of copepods dominated. In reservoirs where sustainable fishing was implemented (K2, K3), trophic parameters of water were lower, on average, by 25%, turbidity by 30%, and productivity by 35–70%. Zooplankton diversity was significantly higher; rotifers and small cladocerans dominated. The choice of recreational fishing model determines the functionality and biological potential of the reservoir.

休闲垂钓对露天矿排水系统水库浮游动物群落的影响

使用人工水体钓鱼是一种流行的做法，尤其是在失去天然水体的工业和城市化地区。在这项研究中，三个露天矿排水系统水库的浮游动物结构动力学和水质通过不同类型的休闲渔业开发进行了评估：K1——使用捕获和释放模型的密集垂钓，K2——最低的垂钓压力和较高的捕食性鱼类和 K3——中度捕鱼，即限制地饵数量并消除垂钓者的非掠食性鱼类。检验的零假设是休闲捕鱼不影响水库的生物和非生物条件。使用冗余分析 (RDA) 测试每个环境变量的显着性。最高的养分和叶绿素a浓度，浊度水平和有机物含量发生在 K1。在这些条件下，浮游动物的多样性最低；桡足类的原生动物和幼虫阶段占主导地位。在实施可持续捕捞的水库（K2、K3）中，水的营养参数平均降低 25%，浊度降低 30%，生产力降低 35-70%。浮游动物多样性明显更高；轮虫和小型枝角类动物占主导地位。休闲捕鱼模式的选择决定了水库的功能和生物潜力。和生产力提高 35-70%。浮游动物多样性明显更高；轮虫和小型枝角类动物占主导地位。休闲捕鱼模式的选择决定了水库的功能和生物潜力。和生产力提高 35-70%。浮游动物多样性明显更高；轮虫和小型枝角类动物占主导地位。休闲捕鱼模式的选择决定了水库的功能和生物潜力。
