Moreover, it is generally known that aquatic animals and fish may uptake these compounds present in drainage water and in phytoplankton then bioaccumulation (Arnot and Gobas, 2004). Fish is a biomarker to environmental contamination thereby, pesticides may cause many physiological and biochemical changes influencing the activities of several enzymes and metabolites (Mukesh, 2013) even exposure to low levels of pesticides have adverse biological effects (Hernandez et al., 2006). Mullet is very important marine fish and represents both freshwater and brackish water fish.
