Effects of Clove Oil Anaesthesia on Rainbow Trout (Oncorhynchus mykiss)

Abstract

The aim of the study was to investigate acute toxicity of clove oil for rainbow trout and, using values of haematological and biochemical profiles of blood and histological tissue examinations, to assess the effects of the fish exposure to that anaesthetic. Acute toxicity values of clove oil for rainbow trout found were 10 min LC50 81.1 mgl -1 ; 10 min LC0.1 63.9 mgl -1 ; 10 min LC99.9 100.1 mgl -1 ; 96 h LC50 14.1 mgl -1 ; 96 h LC0.1 12.5 mgl -1 , and 96 h LC99.9 16.2 mgl -1 .
