Abstract
Investigations w ere carried to assess the sublethal effects of a herbicide clincher
( 100 EC) containing cyhalofop2butyl [ 100 g (a. i) ·L
- 1
] as the active ingredient and the
insecticide p rofurite2am inium [ 78% SP, 780 g (a. i) ·kg
- 1
] on liver esterases and hepatic
glutath ione2S 2transferase (GST ) in go ldfish (Carassius au ratus) and topmouth gudgeon
(P seud orasbora p arva). GST w as found to be induced in bo th go ldfish and topmouth gudgeon
by the p rofurite2am inium at concentration of 0. 234 m g·L

. Clincher bo th at concentration
of 1 and 2 m g·L

p rofurite2am inium had the h ighest effect in topmouth gudgeon 722. 3 nmo l· (m in

clincher (1 and 2m g·L

topmouth gudgeon liver esterases w ere induced by p rofurite2am inium but inh ibited by
clincher. It is suggested that the two bio transfo rm ation enzym es m ay be directly o r indirectly
affected by the tested chem icals and that there are differences betw een them
