“…Moreover, Cladocera had negative correlation with water temperature,total alkalinity and ammonia (r=-0.361, -0.305 and -0.236), and had positive relation with total nitrogen (p<0.05, r= 0.242). This is in conformity with the study of Dvurechenskaya and Yermolaeva (2014) and Menghong et al (2014).…”

This study was carried out in Nozha hydrodrome, Alexandria, to assess the impact of physico-chemical parameters upon zooplankton community structure and diversity during the period from December 2015 to November. 2016. The results indicated that there were significant monthly variations in physical and chemical characteristics, such as water temperature, pH, dissolved oxygen, total alkalinity, total hardness, nitrite, nitrate, total nitrogen,orthophosphate and total phosphorus. Zooplankton were represented by fifteen genera belong to four groups. Rotifera constituted the main dominant group contributing 82.59% of the total zooplankton, followed by Copepoda (12.33%), Cladocera (3.886%) and Ostracoda (1.22%). The highest density of zooplankton was recorded during January (mean 2504.5 org/ l), while the lowest was found in July (mean 44.25 org/l).The data pointed out that the most effective water variables on composition and distribution of zooplankton were water temperature, total alkalinity, total hardness, ammonia, nitrite, nitrate and total nitrogen. The low value of Shannon diversity index, high value of some water parameters and dominance of pollution tolerant forms of zooplankton revealed that the hydrodrome is suffering from organic pollution.

“…The influence of hydrochemical factors on the zooplankton of the Novosibirsk reservoir is also connected to the peculiarities of hydrological regime in the parts of the water body (Dvurechenskaya and Yermolaeva, 2014). Zooplankton of 20 lakes of Kejimkujik National Park (Canada) was strongly correlated with such factor as elevation, but not with the studied hydrochemical parameters (Bowman et al, 2014).…”

Kurashov et al.: The role of environmental factors in the formation of zooplankton in tributaries of Lake Ladoga - Abstract. The role of environmental factors in the formation of zooplankton in tributaries of Lake Ladoga is still poorly investigated. The authors aimed at exploring composition and quantitative patterns of zooplankton development in the major tributaries of Ladoga and assessing the impact of environmental factors and features of river catchment basins on the parameters of zooplankton development. A total of 137 taxa ranking below genus were identified (56 species and subspecies of Rotifera, 57 of Cladocera, 24 of Copepoda). Species composition and patterns of quantitative development cannot be explained by any environmental factors or their combination. It is impossible to determine groups of rivers with similar patterns of zooplankton development basing on the composition and abundances of individual zooplankton species. River clustering based on hydrochemical and hydrological parameters and features of catchment basins provides an opportunity to distinguish groups of similar rivers. Total abundances of copepoda, cladocera, and rotifera in the rivers are closely associated with certain combinations of studied physiographic parameters. Physiographic factors, namely, the catchment basin area, water discharge, and lake percentage on the territory of the catchment basin, are the most important in the level of quantitative development of Copepoda, Rotifera, and Cladocera in tributaries of Lake Ladoga.

“…These parasitic organisms form an integral part of the zooplankton assemblage during their free-living stage and represent a much sought-after food item of zooplanktonophagic fish (Dussart and Defaye 2001). Over the year, both quantitative and qualitative changes occur in zooplankton composition, with seasonal dynamics mainly affected by changes in abiotic and biotic factors, reservoir trophic status and fish predatory pressure (Wolfinbarger 1999;Pichlová and Brandl 2003;Sommer et al 2012;Dvurechenskaya and Yermolaeva 2014). If predatory fish suppress zooplanktonophagic fish sufficiently, for example, the quantity of zooplankton increases, positively affecting the quality of raw drinking water (Tatrai et al 2005;Bernes et al 2015;Jurajda et al 2016).…”

Relationship between seasonal dynamics in zooplankton density and Ergasilus infection in two reservoirs

et al. 2018

Ergasilosis is a common parasitic disease of fish caused by species of the family Ergasilidae. During the fish growing season, parasitic abundance (including developmental stages) changes in relation to zooplankton development. In this study, we evaluated the seasonal dynamics of ergasilosis in relation to zooplankton development at two reservoirs (Hubenov, Koryčany) in the Morava River Basin (Czech Republic). Samples of fish and zooplankton were obtained at monthly intervals between April and October 2014. In total, 189 fish of 11 species were caught using electrofishing and seine nets. Overall, epidemiological characteristics were higher in the Hubenov reservoir, which also hosted higher numbers of pelagic Copepods. Hubenov also supported a higher number of predatory fish species, which presumably helped to reduce the number of zooplanktonophagic cyprinids. Our results suggest that each reservoir represents a unique ecosystem with its own pattern of ergasilosis seasonal development. Differences between reservoirs are closely related to zooplankton development, which is in turn affected by the fish stock in each reservoir. As the nauplius and copepod stages of arthropods form part of the zooplankton assemblage, they will be found at highest numbers in reservoirs where predatory fish suppress zooplanktonophagic fish species. We suggest to analyse zooplankton with the determination of the genus Ergasilus. Parasite, ergasilosis, food web, biomanipulation, Hubenov, KoryčanyRepresentatives of the subclass Copepoda play an essential role as part of the food chain in aquatic ecosystems. These parasitic organisms form an integral part of the zooplankton assemblage during their free-living stage and represent a much sought-after food item of zooplanktonophagic fish (Dussart and Defaye 2001). Over the year, both quantitative and qualitative changes occur in zooplankton composition, with seasonal dynamics mainly affected by changes in abiotic and biotic factors, reservoir trophic status and fish predatory pressure (Wolfinbarger 1999;Pichlová and Brandl 2003;Sommer et al. 2012;Dvurechenskaya and Yermolaeva 2014). If predatory fish suppress zooplanktonophagic fish sufficiently, for example, the quantity of zooplankton increases, positively affecting the quality of raw drinking water (Tatrai et al. 2005;Bernes et al. 2015;Jurajda et al. 2016). On the other hand, such a reduction in cyprinids may increase the occurrence of parasites whose development is bound to that of zooplankton as the freeliving nauplius and copepod stages of parasites such as Ergasilus sieboldi Nordmann 1832, for example, form part of the zooplankton assemblage. In the life cycle of E. sieboldi are six free-swimming nauplii stages and five copepodite stages, from which free-swimming adult males and females develop. The development of the parasite usually lasts from 10 to 70 days depending on water temperature. Adult females then attach to the gills of many fish species, feeding on the gill epithelium and blood, eventually impairing the
