“…Low levels of Pb pollution could cause some adverse effects on fish health and reproduction [198]. Also, lead was found to inhibit the impulse conductivity by inhibiting the activities of mono aminooxidase and acetylcholine esterase, to cause pathological changes in tissue and organs [199] and to impair the embryonic and larval development of fish species [200]. Hou et al [201] monitored the effect of lead on the Chinese sturgeon, Acipenser sinensis.…”

The present review gives a brief account of the toxic effects of heavy metals on fish. In aquatic ecosystem, heavy metals are considered as the most important pollutants, since they are present throughout the ecosystem and are detectable in critical amounts. Heavy metals, such as mercury, cadmium, copper, lead and zinc are of the most important pollutants which effect aquatic environment and fish. They are extremely dangerous for the health of fish. Most of these metals are characterized by being accumulated in tissues, and lead to the poisoning of fish. These metals can effectively influence the vital operations and reproduction of fish; weaken the immune system, and induce pathological changes. As such, fish are used as bio-indictors, playing an important role in monitoring heavy metals pollution. Finally, some recommendations are given to treatment of different kinds of wastewaters, sewage and agricultural wastes before discharge into the aquatic systems. Also, enforcement of laws and legislations regarding the protection of aquatic environments must be taken into consideration.

“…The study results showed that the concentration of nickel was high in the liver of fish that collected from the polluted basin (0.0021 ± 0.34 mg kg -1 ). Nickel inhibits the impulse conductivity by inhibiting the activities of monoamine oxidase and acetylcholine esterase to cause pathological changes in tissue and organs (Rubio et al, 1991) and impair the embryonic and larval development of fish species (Dave and Xiu, 1991).…”

Accumulation of some heavy metals (copper, iron, manganese, nickel and zinc) and its effect on the hematological indices on the freshwater fish (Oreochromis niloticus) were studied. Fish Samples were collected from the River Nile near El-Kanater El-Khyria and contaminated water from Iron and Steel Basin in El-Safe Village near Helwan, south of Cairo. Results of this study showed that there was a significant difference between the water qualities indices among the two different locations. Meanwhile, fish samples that collected from polluted location showed high values for the hematological indices namely hemoglobin (Hb), red blood count (RBC), hematocrit (Hct), white blood cell count (WBC) and erythrocyte. Moreover, the concentrations of heavy metals were also high in the fish. However, the levels of the heavy metal accumulation were within the maximum permissible limit for human consumption (FAO, 1992). The order of bioaccumulation of such metals in the liver of fish were Fe > Zn> Cu > Mn > Ni. It was concluded for this study that the discharge of different types of wastes, especially heavy metals from washing process of Iron and Steel in Helwan Company deteriorated the water quality and consequently affecting the fish. It is recommended to treat the different wastes before discharging to Iron and Steel Basin in ElSafe Village.

“…Doughtie and Rao (1984) also observed lamellar irregularities in the gills of the grass shrimp, Palaemonetes pugio, upon exposure to chromium and Rubio et al (1991) in the American red crayfish Procambarus clarkii on exposure to lead. Xu (unpublished data from this laboratory) observed disintegration of cell epithelial junctions in the gill of G. pulex after 2-d exposure to 1.5 mg Zn/L, although Maltby et al (1990) reported no respiratory changes in G. pulex after 6-d exposure to zinc.…”

The use of oxygen consumption as a measure of metabolism has resulted in the development of many types of respirometer. These can be classified into three types. Firstly, there is the closed system in which oxygen concentration is measured at the beginning and end of the experiment and an organism's respiratory rate calculated from the decrease in oxygen concentration and the volume of the vessel (e.g., Franke 1977). Secondly, there is a system in which respired oxygen is replaced by oxygen from the surrounding air and the resultant change in air volume is measured gasometrically (e.g., Pascoe et al. 1968). A third approach, and the one employed in this study, utilises an open flow-through system in which water passes through a chamber containing an animal and the oxygen concentration is measured and compared to that of a reference chamber without an animal. The difference in oxygen concentration is then used to determine the respiration rate of the test animal.In open flow-through systems excretory products are washed away and water is not left stagnant as may occur in closed techniques. In addition, the open flow technique provides a constant oxygen concentration, avoids stress to animals with oxygen concentration-dependent metabolism and allows the simulation of low oxygen tension environments. Despite these obvious advantages the use of flowthrough respirometers has been somewhat limited due to difficulties in calibration and complexity in construction and operation (Edwards and Learner 1960).The purpose of this investigation was to design a flow-through respirometer which is sufficiently sensitive to detect pollutant-induced respiratory changes in freshwater invertebrates and which permits automated continuous recording of the respiration of several animals maintained individually. In order to evaluate the system the effect of copper (prepared from cupric sulphate, CuSO 4 .5H 2 O) on the respiration of the shrimp Gammarus pulex was studied.
