Haematological effects of 2-phenoxyethanol and etomidate in carp (Cyprinus carpio L.)

Deep anaesthesia with 2-phenoxyethanol or etomidate induced significant haematological alterations in juvenile carp. Deep sedation reduced the immediate immunosuppressive effects of handling but did not eliminate longterm effects. These anaesthetics should be avoided during experimental procedures involving haematological measurements. In contexts that require the short-term handling of carp, these drugs should be used with caution in view of their possible side effects.
