“…According to Bellinger and Sigee [13], phytoplankton are the micro-plant organisms without distinct roots, stems and leaves. The phytoplankton community plays a key role in aquatic ecosystems as bioindicators and primary producers; providing for carbon xation, oxygen and food production [14]. Phytoplankton species are able to survive and develop in diverse aquatic habitats but each species is restricted to a de ned niche based on their physiological requirements and environmental limitations [15].…”

Certain anthropogenic activities have negative impacts on the aquatic ecosystems. Plankton are sensitive to their environment and are used to monitor anthropogenic impacts. A South-eastern Nigeria River was studied from December 2017 to November 2018 in 6 stations; to assess the plankton community, water quality and anthropogenic impacts. The river was subjected to intense sand mining activities among other activities. The plankton was sampled with filtration method while water was collected and analysed using standard methods. A total of 36 phytoplankton species and 27 zooplankton species were recorded with Chlorophyceae and Rotifers being the most abundant groups. The most abundant species - Melosira granulata (phytoplankton) and Daphnia pulex (zooplankton) are pollution indicators. Some of the physicochemical parameters showed that the river was perturbed by the anthropogenic activities in the watershed. However, the plankton assemblage and community structure gave an indication of a stable environment; though the zooplankton fauna showed some level of stress. The impacts of sand mining activities on water quality and plankton were more in the downstream stations (4–6) where sand mining was intense while perturbation from swimming children and related activities were observed in station 1 especially during the dry season. The presence of eutrophic indicators and tolerant species showed that the river was tending towards eutrophication. Sand mining activities contributed to the nutrient enrichment of the river. CCA showed the major water quality parameters that influenced the plankton community structure. There is need to regulate illegal sand mining activities in the river.

“…This biota can provide information on water condition, one of which is as an indicator of pollution (Igwe et al, 2019;Krupa et al, 2020). Research on the use of phytoplankton as a bioindicator has been conducted by Fatmayanti et al, (2019), Yusuf (2020), and Zhu et al (2021), while research on the use of zooplankton as a bioindicator has been conducted by Neto et al (2014). This study aims to assess the presence of plankton species, their abundance and diversity as aquatic ecological bio-indicators in Kakap River Estuary.…”

Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities. This study aims to assess the presence of plankton species, their abundance and diversity as aquatic ecological bio-indicators in Kakap River Estuary. Plankton and water samples were taken for three months, with a frequency of one sample per month, viz. in March, April and June 2020 from four sampling stations in Kakap River Estuary, West Kalimantan. A total of 34 species of plankton were observed from all sampling sites, and identified to belong to 18 classes. Chlorophyceae had the highest relative abundance among the phytoplanktons (40.10%), followed by Bacillariophyceae (21.86%) and Cyanophyceae (19.28%). Oscillatoria sp. and Hydrodictyon sp. were the most dominant phytoplankton species. There were 8 classes of zooplankton identified from all sampling stations throughout the research period. Hexanauplia had the highest relative abundance among the zooplanktons (36.56%) followed by Euglenophyceae (24.37%). The plankton diversity index (H ′) values ranged between 2.33 -3.11. The plankton evenness index value ranged from 0.79 to 0.89 which indicates high plankton evenness at all samping stations, and this is supported by a low dominance index value at all stations ranging from 0.06-0.16. Station 1 had high Shannon-Wienner diversity index score, while for station 2, 3, 4, their scores were in the moderate level. Overall. the diversity index of the plankton from all sampling sites indicated that the quality of the water had no pollution to light pollution level.Keywords:PhytoplanktonZooplanktonWater quality

“…During the present study, the maximum species were recorded in winter season (Table-3). The maximum taxa richness and density of benthic fauna observed during winter season which favors low temperature (Yusuf, 2020) [12] and more dissolved oxygen (Negi and Sheetal, 2013) [6] for the benthic population. Also, density is more due to the availability of phytoplankton population in the form of food source (Joshi et al, 1996) [4] .…”

The present study was aimed to assess the diversity, distribution and abundance of macrozoobenthos in Parbati River (Madhya Pradesh). During the present investigation, 5 sampling stations were selected to collect the samples. Shannon diversity index and Margalef's richness index was used on benthic data obtained during the survey. A total of 50 taxa of macrobenthic fauna were recorded from different sampling stations of Parbati River. The phylum Arthropoda was found dominant followed by mollusca and annelida. The maximum diversity and richness were recorded during winter season while minimum diversity was recorded during monsoon. Among the EPT, Ephemeroptera were reported only at the reference site, while Plecoptera and Trichoptera were absent at all the stations.
