“…Studies have shown that the phytoplankton of riverbed ponds located on the rivers of the Azov-Kuban plain is represented by 125 taxa of algae belonging to 9 groups: Chlorophyta -37 taxa, of which Protococcophyceae -28, Volvocophyceae -6, Desmidiales -3, Bacillariophyta -33 taxa, Euglenophyta -16, Cyanophyta -26, Pyrrophyta -8, chrysophyta -3 and Xanthophyta -2 taxa. The results obtained are comparable to previous studies within the Azov-Kuban plain [8] Zooplankton is represented by three typically planktonic groups of organisms: Rotatoria, Copepoda, and Cladocera [9,10]. The zooplankton species analysis identified invertebrates belonging to 24 taxa: Rotatoria-16, Copepoda-4, Cladocera -4.…”

The article presents calculations and recommendations for fisheries development and improvement of fish productivity of riverbed ponds of the Azov-Kuban plain on the example of the Kirpili river. We studied the taxonomic composition and calculated the biomass of the natural fish food base of the studied reservoirs, which includes: phytoplankton-383.5±0.24 kg / ha; zooplankton-86.8±1.14 kg/ha; zoobenthos – 28.7±1.30 kg/ha, macrophytes – from 10 to 45 kg / m2. The species composition of the Kirpili river ichthyofauna includes 11 species of fish. With the aim of pasture aquaculture stocking of channel ponds lowland rivers it is necessary to produce fingerlings Hypophthalmichthys molitrix, Hypophthalmichthys nobilis, Ctenopharyngodon idella, and as addition Cyprinus carpio, Mylopharyngodon piceus, Liza haematocheila, Polyodon spathula, etc.) individual weight below 25-30 g, which will allow you to fish more 1350,0 kg/ha.

The combined effects of eutrophication, land-use and climate change are major threats to aquatic ecosystems, their biodiversity and integrity in sustaining ecosystem functions. Disentangling the mechanisms by which environmental change contributes to community assembly processes and species niches remains challenging, especially at macro-ecological scales. Here, we collated phytoplankton community data including 853 lakes along a 1200km latitudinal gradient, monitored over four decades, to quantify the spatio-temporal and scale-dependent environmental impacts on species niches and assembly processes while accounting for species traits and phylogenetic constraints. Our results demonstrate the emergence of novel and widespread community composition clusters in previously more uniform communities. While total species richness remained relatively stable, changes in community weighted mean traits of the clusters indicate functional differences. A robust phylogenetic signal of species responses to the environment indicates strong niche conservatism and low taxonomic dispersion. Our findings imply profound spatio-temporal structuring of species co-occurrence patterns and highlight emerging functional differences of lake phytoplankton communities to environmental change over space and time.

“…Also, predation pressure reduces their densities (De Stasio, 1989), which display low abundances of resting eggs in the sediments and consequently only some invertebrate species are found in the water. Long-term observations of the invertebrate community are important in order to understand the changes in water quality (Ovaskainen et al, 2019).…”

Aquatic invertebrate diversity reflects water quality and the health of aquatic ecosystems and should be monitored as an essential feature of freshwater ecosystems. The resting eggs of aquatic invertebrates in sediments populate the overlying water. The diversity of invertebrates in waters and their resting eggs in sediments in Baiyangdian Lake, Xiongan, North China, were assessed using high-throughput sequencing (HTS) with a pair of 18S rRNA gene adaptor-linked primers. The total of 99 operational taxonomic units (OTUs) derived from 353,755 invertebrate sequences (mostly zooplankton) were revealed by this study. A total of 50 species in the water samples including 20 rotifers, 11 copepods, 1 cladoceran and 18 other species were sorted out. In the sediment 37 species, including 21 rotifers, 3 copepods, 1 cladoceran and 12 other species, were identified. There were 24 species in common between water and corresponding sediments. Invertebrate OTU richness in water samples was higher than that in sediments (p < 0.01), while there was no significant difference in the Shannon-Wiener index. These results suggest that HTS is a promising alternative for efficient biodiversity assessment and monitoring.
