Abstract

The study has been focused on the population composition dynamics and trophic relationships of Simocephalus vetulus (O.F. Müller, 1776) in the absence of the food stress of ichthyofauna in flow-through ecosystems in Patriarshie Prudy pond. The role of S. vetulus species in the plant-eating zooplankton, the suppression of blooming, and the preservation of high water transparency have been assessed. The largest daily consumption of edible phytoplankton biomass by zooplankton under flowage has been shown to be 102.96 mg/L in late August at maximal biomass and dominating S. vetulus (up to 99.8% of the biomass of plant-eating zooplankton).

通过流经生态系统中的浮游动物过滤来抑制水体中浮游植物的开花

摘要

这项研究的重点是在Patriarshie Prudy池塘流经生态系统中缺乏鱼腥藻食物压力的情况下，Simocephalus vetulus（OFMüller，1776）的种群组成动态和营养关系。已评估了维氏链球菌在食植物浮游动物，抑制开花和保持高水透明度中的作用。浮游动物在流量下的最大可食用浮游生物量日消耗量已显示为8月下旬的最大生物量和占优势的S. vetulus（高达食植物浮游生物量的99.8％）为102.96 mg / L。
