The compound works by inhibiting the enzyme acetylcholinesterase (AChE), which is responsible for degrading the neurotransmitter acetylcholine (ACh). The trichlorfon LC SB 50 sb -96h value for tambaqui found in our study was 0.870 mg/L with a 95% Fiducial CI ranging from 0.0656 to 1,154 mg/L. Rocha ([15]) in his dissertation also calculated the LC SB 50 sb -96h of trichlorfon in tambaqui and found the value of 0.820 mg/L (Rocha, [15], unpublished data). In immersion baths, trichlorfon dosage and bath time are considered, but extended immersion periods, combined with high dosage of the compound, can cause fish mortality (Flores-Nava & Vizcarra-Quiroz, [8]). In the current study, during the study, it was noted that the fish submitted to high trichlorfon concentrations had tight muscles and showed frequent spasms when compared with control animals.
