  The aim of this study was to evaluate the anesthetic efficacy of essential oils of clove, mint and camphor to clownfish Amphiprion ocellaris and their effects on water quality in simulated confinement transport conditions. Anesthetic effects of clove, mint and camphor oils were tested at concentrations of 2.5, 5.0 and 7.5 μL L-1; 20, 25 and 30 μL L-1; and 100, 120 and 140 μL L-1, respectively. Confinement periods of 6 h, 12 h and 24 h were simulated (n=8 fish/time/concentration). Animals were randomly selected and transferred to polyethylene bags (16 × 30 cm, 5 fish L-1). Water concentrations of dissolved oxygen (DO), nitrogen in the form of total ammonium (N-TA=NH3+NH4 +) and non-ionized ammonia (N-NH3) and pH were measured before closing and after opening the bags. Different confinement densities of A. ocellaris (5, 10, 15 and 20 fish.. View More»
