“…The Phongolo River floodplain wetlands featured muddy substrates and abundant aquatic floating vegetation (Dube et al., 2017 ), while Lake Shokwe had minimal aquatic vegetation, mainly consisting of marginal vegetation (van Rooyen et al., 2022 ; Whittington et al., 2013 ). These differences in physical habitat likely contributed to variations in aquatic invertebrate diversity, as greater availability of habitat structures positively correlates with high biodiversity (Brendonck et al., 2022 ; Collier et al., 2016 ; Dube et al., 2022 ; Piedade et al., 2022 ). Furthermore, the aquatic invertebrates in these floodplain systems showed adaptations to low oxygen conditions, using spiracles or plastrons for air breathing.…”

“…Aquatic invertebrates are an essential component of aquatic ecosystems, influencing ecosystem processes in various ways including periphyton control and acting as a food source for organisms at higher trophic levels (Chanut et al., 2020 ; de Necker et al., 2016 ; Majdi et al., 2022 ; Majdi & Traunspurger, 2017 ). These organisms encompass a diverse group of species with a widespread distribution and range of traits and adaptations to ensure survival in various aquatic environments (de Necker et al., 2021 ; de Necker, Brendonck, et al., 2022 ; Dube et al., 2022 ; Jeffries et al., 2016 ; Lake, 2011 ; Wantzen et al., 2016 ). Furthermore, aquatic invertebrates are known to undergo shifts in community composition in response to anthropogenic stressors (Akamagwuna et al., 2022 ; Cai et al., 2017 ; Foster et al., 2015 ; Helson & Williams, 2013 ; Magbanua et al., 2010 ; Mangadze et al., 2019 ; Ntloko et al., 2021 ; Villastrigo & García‐Criado, 2017 ).…”

“…Anthropogenic and climate‐driven alterations to these natural flooding/drying cycles pose a significant risk to the community composition of aquatic invertebrates, which may result in not only a loss or extinction of species, but also in alterations in the food web structure of these ecosystems (Batzer & Boix, 2016 ; Covich et al., 1999 ; de Necker, Brendonck, et al., 2022 ; Dube et al., 2022 ; Dudgeon et al., 2006 ; Jeffries et al., 2016 ; Zimmer et al., 2016 ). It is therefore essential to monitor the community composition of all aquatic biota in regulated ecosystems that experience climate‐driven drought events.…”

While natural floods play a crucial role in shaping the composition of aquatic communities, the most rivers worldwide are regulated or dammed for anthropogenic purposes, resulting in alterations to the biological and chemical composition of these ecosystems. Studies have demonstrated various negative effects of river regulation on aquatic invertebrate communities globally. However, there is a scarcity of research in Africa, despite its vulnerability to anthropogenic impacts. This study aimed to compare aquatic invertebrate communities in the Phongolo River, an impacted regulated river, and the Usuthu River, a less impacted unregulated river, in South Africa. It further aimed to ascertain whether Lake Nyamithi, a naturally saline lake receiving water from both of the aforementioned systems, exhibited a stronger similarity to one of the two rivers in terms of its aquatic invertebrate composition. Aquatic invertebrate and water samples were collected from 2012 to 2018 over several surveys. The Usuthu River demonstrated a diverse and sensitive aquatic invertebrate community, emphasising its high conservation value. The Phongolo River demonstrated effects of anthropogenic impact, with taxa more resilient to changes in water quality and flow compared to the Usuthu River. Mismanagement and excessive water use may lead to the loss of any remaining sensitive aquatic invertebrate communities in this river. The presence of invasive molluscan in the Phongolo River and Lake Nyamithi also poses a threat to the native aquatic invertebrate communities. These invasive species are currently absent from the Usuthu River although other invasive species, such as the Australian redclaw crayfish, are found in both river systems. Lake Nyamithi displayed a unique aquatic invertebrate community, distinct from both rivers and their floodplains. This study provides important baseline information on the Usuthu River's aquatic invertebrates and emphasises the need to maintain adequate water flow in rivers and floodplains to protect biodiversity and sensitive species.

“…Diatoms are unicellular microscopic algae living in all aquatic environments with sufficient light (Dixit et al, 1992). Macroinvertebrates are key components of lotic ecosystems, comprising species with a high variability in terms of environmental tolerance and habitat preference (Arenas-Sánchez et al, 2021;Dube et al, 2021).…”

“…The total number of invertebrates (abundance) and the number of different kinds of invertebrates (richness) can both be used to assess the health of aquatic ecosystems. In general, high benthic macroinvertebrates richness indicates the healthier the aquatic system [9]. An aquatic system could imply as under stress with less richness of benthic macroinvertebrates.…”

Overall, small holder of fish farmers in Kelantan in particular does not monitor their pond water quality to maintain fish health due to tedious and expensive work. Hence, this study was proposed to identify the assemblages of benthic macroinvertebrates at the fish pond for potential as a tool for water quality assessment via biological indicator. The study area was in one of the small holder fish pond at Gua Musang, Kelantan, Malaysia. Benthic macroinvertebrates were collected monthly from March to August 2021. Benthic macroinvertebrates were collected by using a heavy-duty D-frame dip net combined with a bag-shaped. The ecological indices were calculated (Shannon diversity index, Margelef’s richness index, Pielou’s evenness index, and Simpson’s dominance index). Results showed a total of 356 individuals from 27 taxa of aquatic insects were collected. Corixidea (Hemiptera) recorded high abundance in July 2021. Even though there were differences in the abundance of benthos for monthly sampling, the season was only a part of the factors that might contribute, however the other factors cannot be neglected such as food availability, water quality and substrates composition conditions. Hopefully the findings could be used by the small holders to assess their pond water quality effectively with minimum cost.
