“…The quality of water is essentially determined by the abundance of plankton to determine the fertility level of the water. Plankton has a short life cycle and reacts quickly to environmental changes, making it an indicator that provides signs in determining water quality 39) . The abundance of plankton is also used to monitor the fertility level of the water 24) .…”

The presence of heavy metals and other contaminants may indicate the presence of a biological response in aquatic animals. This research investigates the heavy metal contamination and water quality on the immune response (IL-1β) of wader fish (Barbonymus gonionotus) in response to the presence of contaminants in the waters of the Porong River. The location area was selected because of its diverse utilization surrounding the river, including residential areas, industrial zones, and agricultural practices. The research procedure includes water quality measurements, plankton analysis, heavy metals exposure, and immune response (IL-1β) detection by PCR. In general, the waters of the Porong River were found to be polluted based on the assessment of water quality, as indicated by the measurement of CO2, TDS, TSS, and salinity parameters surpassing the established threshold values. In the waters of the Porong River, the metals Cu, Hg, Cd, and Pb exhibited a descending order of penetrating power as follows: Cu > Hg > Pb > Cd. Conversely, in the sediment samples, the order of penetrating power was Cu > Pb > Cd > Hg. The PCR amplification results indicated the presence of IL-1β response in all examined fish, suggesting that it could be attributed to water contamination throughout the entire sampling site. In addition, the heavy metals contamination in the waters of the Porong River resulted in high expression of IL-1β in the fish sample. The findings lead to the conclusion that the waters of the Porong River are classified as polluted based on the measurements of water quality parameters, namely CO2, TDS, TSS, and salinity, which surpass the threshold values established according to Government Regulation (PP) of the Republic of Indonesia Number 22 of 2021.

“…Notably, the maximum temperature was observed at site 3 during summer (30 • C), while the lowest temperature was documented at site 1 in winter (17 • C) (Figure 2). Temperature variations are influenced by several factors, such as geographic location, shading, water source, thermal inputs, water body size, and depth, resulting in significant fluctuations [23]. Temperature plays a critical role as it dictates the types of organisms capable of coexisting within aquatic ecosystems, including the planktonic community in the River Nile near Shattura Village.…”

“…Temperature plays a critical role as it dictates the types of organisms capable of coexisting within aquatic ecosystems, including the planktonic community in the River Nile near Shattura Village. Additionally, ambient temperature is influenced by various factors, including dissolved oxygen levels, the rate of aquatic plant photosynthesis, and the metabolic activities of aquatic organisms [23,24]. from 11 to 18 cm, which is attributable to agriculture drainage and probably anthropogenic activities [27].…”

The present study investigated the effect of environmental variables on the abundance and distribution of zooplankton in different habitats along the Nile River in Shattura Village. Zooplankton samples were collected from three distinct sites along the Nile River in Shattura Village, each exhibiting different environmental characteristics: Site 1 with vegetation, site 2 lacking vegetation, and site 3 being a drain canal. The study spanned from spring 2020 to winter 2021, during which the physico-chemical parameters of the water were analyzed. Rotifera constituted the majority of the zooplankton (54.73%), followed by Cladocera (20.59%), Copepoda (13.1%), and Ostracoda (8.9%). Among the 52 identified zooplankton species, Rotifera comprised 18 species, Cladocera 13 species, Copepoda 10 species, and Ostracoda 11 species. Site 1 exhibited the highest zooplankton density (44.08%), attributed to the presence of vegetation, followed by site 3 (37.18%), influenced by agricultural drains, and site 2 had the lowest density (18.73%). Zooplankton abundance peaked in summer and declined in winter. Notably, Rotifera abundance increased in populated sites (site 3), whereas other zooplankton groups thrived in less populated areas. Correlation analyses revealed positive associations between Rotifera and Cladocera with electric conductivity, total dissolved solids (TDS), chloride (Cl), calcium (Ca), and sulfate (SO4). Conversely, Copepoda showed positive correlations with water transparency, pH, dissolved oxygen, and biological oxygen demand (BOD). Overall, seasonal variations significantly impacted the zooplankton community, with Rotifera dominating and Ostracoda being the least abundant. High values of the Shannon–Weaver diversity index, richness, and evenness suggested ample food resources and favorable growth conditions. Transparency, conductivity, pH, dissolved oxygen, and BOD were identified as the key influencing parameters on zooplankton abundance. Additionally, vegetation and agricultural drains strongly influenced total zooplankton levels.

Fresh water resources in terms of water quality is a crucial issue worldwide. In Egypt, the Nile River is the main source of fresh water in the country and monitoring its water quality is a major task on governments and research levels. In the present case study, the physical, chemical and algal distribution in Nile River was monitored over two seasons (winter and summer) in 2019. The aims of the study were to check the seasonal variation among the different water parameters and also to check the correlations between those parameters. Water samples were collected from the Nile in Cairo governorate in EGYPT. The different physiochemical and microbiological properties in water samples were assessed. The studied parameters were included: temperature, turbidity, dissolved oxygen, chemical oxygen demand, pH, electric conductivity, total dissolved solids, total hardness, anions and cations. Also, the total algae count, blue-green algae, green algae, diatoms, unicellular and filamentous algae were monitored. The results revealed that during winter season the values recorded for (turbidity, total dissolved solids, pH, total alkalinity, total hardness, dissolved oxygen, chemical oxygen demand as well as nitrate, sulfate, chloride, fluoride ions, calcium and magnesium) were higher than during summer. While other parameters including ammonia, nitrite, silicate, carbon dioxide, phosphate, manganese, iron and residual aluminium were higher in summer compared to winter. The data showed a variation total algal count of 4600 to 6500 unit/ml in winter and varied from 3100 to 4500 unit/ml during summer season with predominance of diatoms. The recorded Pearson’s correlations indicated several significant correlations between tested parameters. In conclusion, although there were several variations in tested water quality parameters though all results were within the permissible limits set by the World Health Organization for drinking water.
