Abstract

This study evaluated the use of essential oil of Ocimum gratissimum (EOOG) for anesthesia and in transport of Colossoma macropomum. Experiment 1, Test 1, anesthesia induction and recovery times were determined using different EOOG concentrations (0, 20, 50, 100, 200, 300 mg L−1), with two size classes: Juveniles I (0.86 g) and Juveniles II (11.46 g) (independent tests in a completely randomized design). Based on the results of Test 1, in Test 2 Juveniles II were exposed to EOOG concentrations: 0, 20, 100 mg L−1. Tissue samples were collected immediately after induction and 1 h post-recovery, to assess oxidative status variables. Experiment 2, Juveniles I (0.91 g) and Juveniles II (14.76 g) were submitted to transport in water with different concentrations of EOOG (0, 5, 10 mg L−1) (independent tests in a completely randomized design). The effects on oxidative status variables were evaluated. Concentrations between 50 and 200 mg L−1 EOOG can be indicated for Juveniles I, while concentrations between 50 and 100 mg L−1 EOOG for Juveniles II. The concentration of 100 mg L−1 EOOG was able to prevent oxidative damage in the liver. In Experiment 2, the concentrations of 5 and 10 mg L−1 EOOG added to the transport water caused sedation for both studied size classes of juveniles and did not cause oscillations in water quality variables nor any mortality. The concentration of 10 mg L−1 EOOG improved the oxidative status. It can be concluded that EOOG can be used for anesthesia and transport of C. macropomum.

Highlights

• This is first study on the oxidative responses of juvenile of Colossoma macropomum exposed to essential oil of Ocimum gratissimum L. (EOOG).• EOOG was efficient for anesthesia of juvenile C. macropomum and improved the protection by the oxidative defense system after anesthesia and biometric handling.• Simulated transportation with 5 and 10 mg L−1 EOOG induced sedation of juvenile C. macropomum.
