“…This could be due to the decreased rate of decomposition of organic matter at low temperature and low metabolic activity of aquatic organisms (25). The chemical oxygen demand (COD) is usually regarded an indicator for determining the level of water pollution (6). The WHO sets the permissible limit for COD as 40mg/l (21).…”

“…Chloride and fluoride had higher concentrations in winter compared to summer recording a variation from 16 to 37mg/l for (Cl -) and 0.35 to 0.6 mg/l for (F -). According to El-Feky et al (6), the rates of anions and cations in water differ naturally depending on climatic and geographic conditions.…”

“…The quality of water is usually interpreted by its physical, chemical and biological characteristics. Water quality defines water conditions concerning the necessities of one or more biotic species and or to any individual requirement or purpose (6). For any aquatic ecosystem, the physicochemical parameters of water are principle keys for the identification of its origin, quality and type.…”

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.

“…Water quality analysis is used to describe the environmental condition of any water body (El-Feky et al, 2018;Ashour et al, 2018;El Raey and Abo-Taleb, 2019). The change in water quality affects all aquatic organisms; from microorganisms to large creatures (AboTaleb, 2019).One of the most important methods in water quality determination is a heavy metal analysis.…”

The concentrations of heavy metals Cu, Cd, Pb, and Zn in the Abu-Qir water and in the edible portions of the inhabitant common invertebrate Portunus pelagicus were determined in the period (spring 2016-winter 2017). Generally, there was an increasing in the concentration of these measured elements comparing with the previous studies. The obtained data indicated a seasonal and spatial variation of heavy metals concentrations. The highest concentrations in the bay water were recorded during summer season, while spring showed the minimum values. On the other hand, the element levels in the crab tissue were the maximum during autumn and the minimum during winter, among the measured heavy metals Pb was the highest concentration element both in the water and in the animal tissues. It was noticed that the site located near the connection with Lake Edku (Lake-Bay connection) recorded the maximum readings which reveals the effect of the discharged water from the lake.

Zooplankton is the source of life for most of aquatic organisms especially in their larval stages. Its importance come from that most fishes depend on it as a source of life after absorbance of the yolk sac. Moreover, the greatest aquatic creatures like many species of whales are filter feeders where the planktonic organisms form the main bulk of their food. The importance of zooplankton as a main source of nutrition of marine fish larvae has been long professed. Many scientists attributed the ability of a fish population to outdistance through the larval period without vast mortality as one of the primary factors determining the size of the resulting year class and hypothesized that competition for food during the larval time might be a major factor affecting survival and subsequent year class strength.
