“…Hepatic cellular damage also leads to the leakage of these enzymes, which consequently led to their leakage or rupture into the blood circulation (Mouse et al, 2008). These findings also agree with the study of Fatma and Nahed (2000); Yamawaki et al (1986) and Shalaby (2007).…”

Fish can be considered as a good organism for bio-indicator in aquatic habitats as they accumulate contaminant from the water bodies through food. Aquatic ecosystem pollutants response in fishes can lead to biochemical changes and histological alterations. This present the need in assessing ecological and public health effect of toxicity in Asa river on the selected fish samples that are commercially important in the environment. Two stations of Asa river were selected where water and fish were collected for physicochemical parameters of the water, enzymatic and histological investigations in the laboratory in April, 2019. The heavy metals of the water in Unity area of Asa river was higher than that of the standard limit and Asa reservoir. There was an increase in the ALT, AST and ALP biochemical analysis carried out on Oreochromis niloticus and Clarias anguillaris with reduction in total protein level in Unity station. The histopathology of the gills of both Clarias anguillaris and Oreochromis niloticus found in Unity station of Asa river revealed thinner and loner secondary lamella in degenerating secondary lamella and mildly distorted cartilage with epithelial lining in Clarias anguillaris. Hence, proper management of the river is necessary to restore the ecology and make the water fit for use.

“…The highest level of total lipids and triglycerides was recorded in the fish of Radoniqi Lake (p <0.05; p <0.01). Similarly, Shalaby, 2007 andAl-Asgah et al, 2016 found increase of TL and triglycerides in fish exposed to Cd depending on dose and duration of exposure. The level of total protein is often used as a parameter to evaluate not only the toxicity of heavy metals but also the stress caused by environmental pollution.…”

The aim of the current investigation is to evaluate the impact of water quality in hematological and biochemical blood profile in two habitats of common carp (Cyprinus carpio) captured in Batllava and in Radoniqi Lake. It has been found that Radoniqi Lake is characterized with increased levels of physicochemical parameters (T, DO, PO 4-3 , NO 3-N, NO 2-N). In Radoniqi Lake were recorded also heavy metal content such as Cd, Pb, Ni and Cu while in Batllava Lake only presence of Cu was recorded. Given the developed agriculture in the region where Radoniqi Lake is located, increased level of PO 4-3 , Cd and Cu can be attributed to agricultural pollution. Blood is taken for hematological (RBC, Hgb, MCV, MCH, MCHC, WBC), and biochemical (ALP, AST, ALT, Glucose, Cholesterol, Triglyceride, Total lipid, Total protein) analysis from twenty fish of each lake. The results of hematological parameters show that there is a difference between investigated fishes of respective lakes. There are slight differences in the values of Hgb, MCHC and WBC, while the changes are significant in RBC, MCV and MCH. By contrast, the biochemical parameters have shown significant differences, with the exception of the amount of cholesterol, where the differences are insignificant. Given the water quality of the two lakes, the results of this research show that water quality affects the health condition of fish. The high values of hematological and biochemical parameters in the fish of Radoniqi Lake are indicative that these fish suffer from stress caused by water pollution with heavy metals.

“…Cadmium accumulates in tissues of fish easily, showing high affinity to liver and kidneys (e.g., Bentley 1991; Kock et al 1996; Schultz et al 1996; Dallinger et al 1997; De Smet and Blust 2001; Thophon et al 2003; Reynders et al 2006; Shalaby 2007; Wu et al 2007; Ghedira et al 2010; Cao et al 2012). De Conto Cinier et al (1997) observed that Cd reached high concentration in liver earlier than in kidney in carps exposed to this metal.…”

The aim of the present study was to evaluate bioaccumulation of metals in various tissues of the freshwater fish Cyprinus carpio L. exposed to cadmium and copper (a xenobiotic and a microelement). The fish were subjected to short-term (3 h, Cd-S and Cu-S) or long-term (4 weeks, Cd-L and Cu-L) exposures to 100 % 96hLC50 or 10 % 96hLC50, respectively. Blood, gill, liver, head and trunk kidney were isolated weekly from 5 fish of each group for 4 weeks (post-short-term exposure and during long-term exposure). Atomic absorption spectrophotometry technique was applied to measure concentrations of metals (Cd and Cu) in fish tissues. Initial concentrations of copper in fish tissues were higher than levels of cadmium. Cadmium and copper levels increased in all tissues of metal-exposed fish. After short-term exposures (at higher concentration) and during long-term exposures (at lower concentration), similar changes in metal concentrations were observed. The values of accumulation factor (ratio of final to initial metal concentration) were higher for cadmium as compared to copper. Comparison of metal levels and accumulation factors in various tissues revealed that cadmium and copper showed very high affinity to head kidney of common carp (higher than to other tissues), but accumulation factors for cadmium in trunk, head kidney and liver were much higher than for copper. The concentrations of copper in organs of Cu-exposed fish increased only slightly and quickly returned to the control level, which shows that fish organism easily buffered metal level. On the other hand, concentrations of cadmium considerably increased and remained elevated for a long time which suggests that activation of mechanisms of sequestration and elimination of cadmium required more time.
