Organic aquaculture, including carp pond farming, is of growing importance. One of its main characteristics is the health and quality of water environments and maintenance of their biodiversity. In 2013–2014, four organic carp ponds (ORG) in the Waldviertel region (Austria) and four conventional ponds (CONV) in the Třeboň region (Czech Republic), located in the Lainsitz (Lužnice) river basin, were monitored for basic environmental variables, namely hydrochemical and hydrobiological determinants. The aim of this study was to evaluate the performance of organic carp farming technology in the amelioration of carp pond aquatic environment. Aside from temperature, which was probably related to different altitudes, the comparison of physico-chemical environmental variables showed no significant differences between organic and conventional ponds, though dissolved oxygen concentration and saturation, along with turbidity, were higher in ORG ponds, and conductivity was slightly higher in CONV ponds. The mean cumulative richness of zooplankton species was significantly higher in ORG ponds. However, when comparing average richness between both management types, there were significantly fewer rotifer species in ORG fishponds (ORG = 10, CONV = 15; p < 0.01), with total species richness displaying a similar trend (ORG = 17, CONV = 22; p < 0.05). Also zooplankton diversity was significantly (p < 0.05) higher in CONV ponds but no significant difference in zooplankton density and biomass between the two management types was observed in any group of zooplankton. A higher total number of macrozoobenthos taxa was found in CONV ponds (26 taxa) than ORG ponds (10 taxa) and also its cumulative taxa richness was significantly (p < 0.05) higher in CONV ponds (15.8 ± 0.5 taxa) compared with ORG ponds (10.3 ± 0.5 taxa). Despite no significant difference, zoobenthos density was higher in ORG ponds (CONV = 503 ± 113, ORG = 905 ± 682 ind m⁻²; p > 0.05), while its biomass was higher in CONV ponds (CONV = 5.31 ± 0.48, ORG = 4.45 ± 2.17 g m⁻²; p > 0.05).

包括鲤鱼池塘养殖在内的有机水产养殖日益重要。其主要特征之一是水环境的健康和质量以及维持其生物多样性。2013-2014年，对位于La​​insitz（Lužnice）流域的Waldviertel地区（奥地利）的四个有机鲤鱼池塘（ORG）和Třeboň地区（捷克共和国）的四个常规池塘（CONV）进行了监测。变量，即水化学和水生物决定因素。这项研究的目的是评估有机鲤鱼养殖技术在改善鲤鱼池塘水生环境中的性能。除了可能与海拔不同有关的温度外，对理化环境变量的比较显示，有机池和常规池之间没有显着差异，尽管ORG池中的溶解氧浓度和饱和度以及浊​​度较高，而CONV池中的电导率略高。在ORG池塘中，浮游动物物种的平均累积丰富度显着更高。但是，当比较两种管理类型的平均丰富度时，ORG鱼塘中的轮虫种类明显减少（ORG = 10，CONV = 15；p  <0.01），而总物种丰富度显示出相似的趋势（ORG = 17，CONV = 22；p  <0.05）。 在CONV池塘中，浮游动物的多样性也显着较高（p <0.05），但是在任何一组浮游动物中，两种管理类型之间的浮游动物密度和生物量均无显着差异。与ORG池塘相比，CONV池塘（26个分类单元）中发现的大型动物群（26个分类单元）比ORG池塘（10个分类单元）高，其累积分类单元丰富度也显着（p  <0.05）（p5.8）（15.8±0.5个分类单元） （10.3±0.5的分类单元）。尽管无显着差异，但ORG池中的底栖动物密度较高（CONV = 503±113，ORG = 905±682 ind m ^-2；p > 0.05），而在CONV池塘中其生物量更高（CONV = 5.31±0.48，ORG = 4.45±2.17 g m ^-2 ; p  > 0.05）。
