The effects of anaesthetization with different concentrations of benzocaine hydrochloride (BH) and neutralized benzocaine hydrochloride (NBH) were studied on the haematology of Cyprinus carpio. Due to its acidic nature and resultant effects on aquarium water, BH produces haemoconcentration effects with disturbances in acid‐base function. The use of NBH, whereby water quality effects were drastically reduced, improved the general haematological profile. In contrast, haemodilution resulted when blood was sampled without the use of an anaesthetic agent.
