“…Considering that the swimming velocity of fish can be influenced by neurotransmission processes, including alterations of ChE activity (Scott and Sloman 2004), this result suggests the involvement of AChE inhibition in the reduction of the swimming velocity of fish exposed to fenitrothion. These results are in good agreement with similar relationship previously found for other fish species exposed to other organophosphate or carbamate pesticides, for example: in the rainbow trout (Oncorhyncus mykiss) exposed to diazinon and malathion (Beauvais et al 2000;Brewer et al 2001); in the coho salmon (Oncorhyncus kisutch) exposed to chlorpyrifos (Sandahl et al 2005); and in the fathead minnow (Pimephales promelas) exposed to carbofuran (Heath et al 1997).…”

The acute effects of the organophosphate insecticide fenitrothion on Dicentrarchus labrax juveniles were investigated through a bioassay using biomarkers and swimming behaviour as effect criteria. After 96 h of exposure to sub-lethal concentrations of fenitrothion, the swimming velocity and several biomarkers were individually determined, namely: brain acetylcholinesterase (AChE) activity; muscle cholinesterases (ChE), lactate dehydrogenase and isocitrate dehydrogenase activities; liver ethoxyresorufin-O-deethylase (EROD), glutathione S-transferases, glutathione peroxidase, glutathione reductase, catalase and superoxide dismutase (SOD) activities and lipid peroxidation levels (LPO). A significant decrease of the swimming velocity (LOEC = 2 mg l(-1)), an inhibition of both AChE (LOEC = 0.06 mg l(-1)) and ChE activities (LOEC = 0.03 mg l(-1)), and a positive and significant correlation between the swimming velocity and AChE were found in exposed fish, suggesting an influence of the inhibition of these enzymes in the swimming velocity decrease. An increase of EROD activity (LOEC = 1 mg l(-1)), indicating the involvement of this enzyme in fenitrothion biotransformation, and a negative and significant correlation between EROD activity and swimming velocity were also found, suggesting that the two findings may somehow be related. Furthermore, results show a significant induction of SOD (LOEC = 0.13 mg l(-1)) without LPO increase, suggesting that the enzyme is preventing oxidative stress damage. No significant alterations were found in any of the other parameters tested. Thus, exposure of seabass to fenitrothion in the wild at concentrations similar to those tested here may have adverse consequences at population level as neurotransmission and swimming ability are essential for fish performance and survival.

“…However, it is highly toxic to common carp (LC " 0.21 mg/L), particularly when compared to the less sensitive stripped bass (LC "12.10 mg/L) (Finlayson and Faggella, 1986). It has been demonstrated to produce ChE inhibition in larve of stripped bass an fathead minnow (Heath et al, 1993(Heath et al, , 1997. However, there is a lack of knowledge of some important aspects related to ChE analysis in molinate exposure.…”

“…Carbofuran-induced AChE inhibition has been found by several investigators in mammals (Gupta and Kadel, 1989;Trotter et al, 1991;Gupta, 1994). In "sh, previous studies on carbofuran have focused on the e!ects of high concentrations on inhibition of AChE activity (Jash and Bhattacharya, 1983;Trotter et al, 1991;Heath et al, 1997).…”
