چکیده
|
In the present study an attempt has been made to investigate the effect of organophosphate pesticide on aphanius dispar (killifish) through acute toxicity bioassay (24 h). the results showed that the lc 50 values for two pesticides tested were low 0.0025 ppm for chlorpyrifos and 0.039 ppm for methyl parathion indicating high sensitivity of fish juveniles to different pesticides. the treatment with pesticides also resulted in decreased total tissue proteins in a. dispar which reduces the nutritive quality of fish and hence producing negative impact on the health and safety of fisheries products. copyright 2012 zoological society of pakistan.
