浅水湖以小型杂食性鱼类为主，但这些小型鱼类在水生态系统中的作用并不为人所知。在浅水湖的湖泊恢复后，发现一种小型杂食性苦鱼(Acheilognerus Macpterus)为优势种。我们进行了一项中游实验，以考察苦味对水质和浮游生物群落的影响。苦味显著增加了营养物质、叶绿素(Chla)和悬浮固体(TSS)的浓度，降低了光照强度。养鱼处理的浮游植物丰度和生物量均显著高于微囊藻对照组。Dolichospermspp.主宰着浮游植物群落。然而，苦味并没有显著影响浮游动物的丰度和生物量，尽管苦味的存在改变了群落结构，使其以小型物种为主。苦味对营养盐、悬浮物、有机悬浮物和Chlaand浓度的影响与光照强度有关，而对浮游生物和浮游动物/浮游植物生物量的影响不明显。我们的研究表明。大翼藻类可以对水质产生负面影响，促进蓝藻的优势。因此，在恢复或管理浅水湖泊时，应重视对这些小型杂食性物种的监测和控制。
Shallow lakes are dominated by small omnivorous fish, but the roles of these small fish in aquatic ecosystems are not well-known. A small omnivorous bitterling (Acheilognathus macropterus) has been found to be dominant after lake restoration in shallow lakes. We conducted a mesocosm experiment to examine the effects of bitterling on water quality and plankton communities. Bitterling significantly increased the concentrations of nutrients, chlorophylla(Chla) and suspended solids (TSS), and decreased the light intensity. The abundance and biomass of phytoplankton in the fish-present treatment were significantly higher than the controls, withMicrocystisspp. andDolichospermumspp. dominating the phytoplankton community. However, bitterling did not significantly affect the abundance and biomass of zooplankton, although the presence of bitterling shifted the community structure to dominance by small-sized species. Density-dependent effects of bitterling were observed on the concentrations of nutrient, TSS, organic suspended solids and Chlaand on light intensity, but were not found for plankton and ratio of zooplankton to phytoplankton biomass. Our study indicates thatA. macropteruscan negatively affect water quality and facilitate the dominance of cyanobacteria. Therefore, monitoring and control of these small omnivorous species should be emphasized when restoring or managing shallow lakes.
