Fig. 2. Relationships concentration x in Anesthesia of tambaqui Colossoma macropomum (Characiformes: Serrasalmidae) with the essential oils of Aniba rosaeodora and Aniba parviflora and their major compound, linalool

Fig. 2. Relationships concentration x anesthesia induction or recovery time in tambaqui, Colossoma macropomum, exposed to the linalools. a. synthetic linalool; light sedation: y=4.4+(4281/x), r2=0.716, deep sedation: y=-22.5+(12252/x), r2=0.773, deep anesthesia:y=15.3+(17878/x), r2=0.669, recovery: y=43.9+0.66x+0.0015x2, r2=0.712. b. linalool extracted from Aniba rosaeodora; deep sedation: y=29.0+(6010/x), r2=0.784, deep anesthesia: y=-151.3+(60541/x), r2=0.873. Light sedation and recovery: no significant relationship. y = time to reach stage or recovery (s) and x = concentration (µL L-1).
