“…This is supported by previous findings indicating that some heavy metals and pesticides may reduce the activity of CA by catalyzing CO 2 hydration in the gills of teleost fish, which is considered the main compensatory homeostatic mechanism for the regulation of hydrogen ion concentrations and the elimination of excess CO 2 (da Silva and Martinez, 2014;Topal et al, 2014). On the other hand, the inhibition of CA activity may also be related to a decreased synthesis or down-regulation of CA gene expression due to the damage sustained by the branchial chloride and epithelial cells induced by the toxins.…”

“…Laboratory experiments have shown that cadmium exposure results in observed differential behavioural anomalies in different fish species [33] . Dissolved cadmium in freshwater can rapidly cause physiological changes in the gill and kidney of fish by affecting osmotic control and enzyme activity [34] .…”

The distribution of non-essential trace elements in some vital organs of 11 fish species from Aiba Reservoir, Iwo, Nigeria was assessed between November 2010 and June 2011. The fish species belong to seven families; family Mormyridae, family Cyprinidae, family Hepsetidae and family Channidae each with one species; family Bagridae and family Clariidae each with two species; and family Cichlidae with three species. All families, except Clariidae and Channidae, are common in the daily catch from the reservoir. Atomic absorption spectrophotometry was used to determine the levels of cadmium, mercury and lead in fish organs. The concentration of toxic trace metals in fish ranged from 0.001 to 0.100 ppm (Cd), 0.000–0.067 ppm (Hg) and 0.001–0.125 ppm (Pb) dry weight. This study shows similarity (p > 0.05) in the distribution of Cd, Hg and Pb among fish species; and a non-uniform distribution of toxic trace metals within fish organs with Kidney > Liver > Gill ≥ Intestine ≥ Muscle. Canonical variate analysis shows clear discrimination of Clarias macromystax and Channa obscura for gill trace metal levels of Cd, Hg and Pb while Labeo senegalensis and Oreochromis niloticus were discriminated for liver trace metal values of Cd and Pb only when compared to other fish species studied. The discrimination of some fish species based on trace metals in the gills and liver suggests different regulatory strategies for trace metal accumulation. Variation due to comparison among different fish species from the same water body suggests that accumulation may be species dependent. Differential accumulation of toxic trace metals in fish organs makes them good bioindicators of freshwater contamination.

“…Ion-dependent ATPases are known to regulate the entry and exit of different ions across membranes in order to maintain the physiological requirements of cells (Yadwad et al 1990;Agrahari and Gopal 2008). According the available data, TBT and Cd could inhibit ATPase activity in many aquatic organisms (Komoike and Matsuoka 2013;Silva and Martinez 2014;Li et al 2016). The inhibition of such enzyme activity produces membrane depolarization, which leads to the suppression of neuronal and excitatory transmission (Balestrino et al 1999).…”

Tributyltin (TBT) and cadmium (Cd) are two common pollutants in aquatic environments. This study was designed to examine the physiological responses of juvenile Grass Carp Ctenopharyngodon idella to TBT, Cd, and their combination. Fish were apportioned into a control group, a TBT group (7.5 μg/L), a Cd group (2.97 mg/L), and a TBT-Cd group (7.5 μg/L TBT, 2.97 mg/L Cd(2+)) for 7 d. The following activities were measured: Na(+),K(+)-ATPase in gill tissues; nitric oxide synthase (NOS), acetylcholinesterase (AChE), and monoamine oxidase (MAO) in brain tissues; and lipid peroxidation (LPO), malondialdehyde (MDA), total antioxidative capacity (T-AOC), and glutathione (GSH) in liver tissues. Cadmium-induced stress was suggested by alterations in antioxidant responses (MDA, LPO, and T-AOC) and neurological parameters (AChE, MAO, and NOS). Cadmium also induced Na(+),K(+)-ATPase and GSH activity. Compared with the responses among the Cd group, the combination of TBT and Cd not only decreased the level of GSH and Na(+),K(+)-ATPase but also increased the levels of MDA, LPO, AChE, MAO, and NOS. These results suggest that a combination of TBT and Cd could reduce the adverse effects of Cd on Grass Carp. However, the exact mechanisms for the combined effects TBT and Cd on these biomarkers require further investigation. Received September 28, 2015; accepted April 17, 2016.
