“…51 Moreover, kidney damage caused by pollutants may reduce the renal blood flow and glomerular filtration rates, resulting in azotemia, which is characterized by increase in blood urea nitrogen uric acid and creatinine. 52 The reported renal failure in O. niloticus collected from Rosetta branch of the River Nile are in accordance with previous findings in serum of O. niloticus collected from different lakes (Maryut, Manzala, El-Burullus, Edku and Qarun) and the River Nile, 53 and in O. niloticus exposed to aquatic pollution. 54 The main lipids classes in plasma or serum are cholesterol and triglycerides.…”

The River Nile is the essence of life in Egypt, but during the last decades its water quality has been changed by several factors, as a result of anthropogenic activities. The western branch of the River Nile is Rosetta Branch receives different types of pollution. The main origins of most pollutants are El-Rahawy drain and industrial activities in Kafr El-Zayat city. Water samples were analysed for physico-chemical parameters and blood samples for biochemical parameters of the Nile Tilapia; Oreochromis niloticus, to investigate the responses of fish towards these different types of pollution. Samples were collected from three sites from Rosetta branch of the River Nile during summer 2014 and winter 2015. S2 and S3 recorded an increase in water electrical conductivity (EC), total dissolved solids (TDS), biological oxygen demand (BOD) and chemical oxygen demand (COD), while dissolved oxygen (DO) and pH have been depleted. Nitrite, nitrates and ammonia levels also showed an elevation, especially in winter. Moreover, fundamental biochemical parameters such as; glucose, total protein, total lipid, albumin, cholesterol, triglycerides, kidney functions and liver functions in blood serum of O. niloticus recorded remarkable alterations, indicating stressful conditions, caused by the profound pollutants and poor water quality of water at these sites.

“…Meanwhile, in fish, these results agree with Zaghloul et al (2008), Tayel et al (2014), El-Khayat et al (2016) and Ismail et al (2017) who reported highly significant increase in the activities of AST, ALT and ALP in serum of O. niloticus in fish collected from lakes El-Burullus, Manzala and from highly polluted unlined sites at Giza and El-Beharia canals. The same results were reported in case of different fish species exposed to different heavy metals (Elghobashy et al, 2001 andGad, 2005). Another biochemical response; the total protein and glucose and the total serum proteins were used in the diagnosis of fish disease and considered as important indicators for the effect of pollutants on snail and fish Tayel et al (2007) and Saravanan et al (2011).…”

“…Other biochemical responses that used as biomarkers in the present study are creatinine and urea. Elghobashy et al (2001) showed that serum creatinine can be used as a rough index of the glomerular filtration rate as the high concentrations indicate the kidney dysfunction. In the same consequence Bisop et al (1996) cleared that urea is only synthesized in liver from excess amino acids and excreted by kidney and major illness may increase urea levels.…”

“…Among the marked abnormal water quality that was detected in the present study, the increase in un-ionized form of ammonia level (reached 55 mg/L). According to Elghobashy [23], the high un-ionized ammonia level is an indicator of the presence of sewage discharge, agriculture-runoff and industrial effluents and it might be also attributed to the increase in oxygen consumption of the decomposing organic matter and oxidation of chemical constituents. Toxicty due to un-ionized form of ammonia may predispose to asphyxia and mortalities as it is easily spread through the gills causing behavioural, physiological and histological changes [6].…”

The present study was carried out to determine the possible causes of an emergent event of respiratory distress with consequent mass mortalities among Nile fish, Oreochromis niloticus (O. niloticus) at Mariotteya stream, an intrastate tributary of River Nile, Egypt. The area of incident extended from Shabramant till Abouseer city (along 4 km distance) with the direction of water current. Field visits have recorded thousands of dead large sized fish on both sides of the stream while huge numbers of fish of different size accumulated on the water surface showing typical signs of asphyxia. It was also noted that Mariotteya water body is being subjected to multiple sources of pollution through the dumping of improperly treated organic and inorganic chemical wastes in addition to sewage materials. Results of field and laboratory investigations have revealed that, all the examined 60 fish samples were heavily infested with different types of parasites including zoonotic species: Cichlidogyrus arthracanthus (monogenea), Lamproglena monody and Ergasilus sarsi (Copepod), Myxobolus dermatobia, Chilodonella hexastica, Trichodina truttae, Trichodina fultoni, Cryptosporidium spp. and Balantidium spp. (Protozoa), Acanthosentis tilapae.(Acanthocephala), Clinostomum spp., Euclinostomum spp., Heterophid and Prohemistomatid metacercarae (larval of Trematodes). The physical and chemical examinations of water samples and the analysis of heavy metals concentration indicated marked abnormal water quality parameters and environmental pollution which might be incriminated as a primary stress factor that promoted the invasion of parasites as a secondary stress factor. The study concluded that both factors would have interacted to produce this catastrophic intense case of respiratory distress and mass mortalities. The impact of the recorded parasitic infestation and environmental pollution was briefly discussed.
