“…Although a good amount of published works on the use of aquatic insects for assessing health and water quality status of streams exist (Ugbogu andAkiya, 2001 Mafuya et al, 2004;Deliz-Quinones, 2005), many have been focused on open water habitats rather than the littoral zone. Littoral zone studies have been hampered largely by difficulties with quantitative sampling of vegetations and sediment substrata, yet diversity is often high in the littoral habitats as compared with the pelagic zone (Pennak, 1966, Wei et al, 2014, Utete et al, 2017. Analysis of insect community structure in littoral vegetations is indispensable for studies of the biodiversity of the limnetic ecosystem and it forms a veritable tool for assessing water quality.…”

Aquatic insects are species of significant importance to water bodies because they serve various purposes including nutrient cycling, vectors of pathogens and bioindicators of water quality. Analyzing their community structure is a veritable tool in studies of biodiversity and quality of limnetic ecosystems. Therefore, we investigaTed the health status of a pond in Benin City, Nigeria using insect’s abundance, composition, distribution and physicochemical parameters of the waterbody. Insects were sampled using sweep nets and identified to the species level while water samples were collected and analyzed using in-situ and ex-situ methods to determine the physicochemical properties in three sampling stations. The results of the physicochemical assessment of the water indicated that conditions did not differ widely between sites (P > 0.05) except for total alkalinity, and the recorded values were well within the ambient FMEnv permissible limits for surface water except for dissolved oxygen,turbidity and phosphate. A total of 10 insect taxa, comprising of 103 individuals in 2 orders were recorded in the study and among the orders, Hemiptera comprised of 7 species and Coleoptera comprised of 3 species. Majority of the insect fauna found in this study are typically found in similar water bodies in the tropics. However, the obsereved insect community structure revealed a relatively low taxa richness with a dominance of pollution-resistant species which suggests a moderately polluted condition of the waterbody. Keywords: Aquatic insects, bioindicators, biodiversity, water quality, pond.

“…The values of H’ and D were both within the range for normal diversity. In contrast, the value of d was indicated poor diversity, which may be due to the different calculation method for diversity index and the unrecovered evenness of zooplankton after the short-term EAS treatment 40 , 41 .…”

Ecosystem activation system (EAS) technology for remediation of eutrophic freshwater

Ecosystem activation system (EAS) was developed to create beneficial conditions for microbiome recovery and then restore and maintain the ecological integrity (microbial community, phytoplankton, zooplankton) for eutrophic freshwater rehabilitation. A 30 day’s filed test of EAS indicated that over 50% of contaminant was removed and the algae visibly disappeared. EAS treatment 2.5-fold increased the diversity of microbial community and changed the microbial community structure (e.g., two and three-fold decrease in the amount of Flavobacterium and Pseudomonas, typical abundant species of eutrophic freshwater, respectively). Further, the diversity of phytoplankton and zooplankton of treated water suggested that these species were diverse. Representative phytoplankton of eutrophic freshwater, Chlorella and Chlamydomonas were undetectable. The possible mechanism of EAS is restoring the trophic levels of the water body via bottom-up approach by microbial community.

“…Rotifers showed significant contribution in both freshwater and estuarine systems may be attributed to their trophic status as major grazers of algae and small ciliates (Havens, 1991;Arndt, 1993;Tian et al, 2017). The dominant species of rotifer in Damietta estuary belonged to Synchaeta, a genus which is considered to be a marine rotifer (Wei and Xu, 2014) and is common in temperate estuaries (Townsend, 1984;Aboul-Ezz et al, 2014;Wei and Xu, 2014). Synchaeta were represented by 4 species and constituted more than 99% of the total rotifers abundance, likely due to relatively high salinity of the Damietta estuary.…”
