Anesthesia of tambaqui Colossoma macropomum (Characiformes: Serrasalmidae) with the essential oils of Aniba rosaeodora and Aniba parviflora and their major compound, linalool

Abstract

The aim of this study was to determine the anesthetic efficacy of the essential oils (EOs) of Aniba rosaeodora (EOAR) and Aniba parviflora (EOAP) and one of their main compounds, linalool, in two forms: synthetic and extracted from EOAR (linalool-AR) in tambaqui (Colossoma macropomum). In the first experiment, the anesthetic induction and recovery of juveniles exposed to 25- 200 µL L-1 of EOAR or 50- 300 µL L-1 of EOAP or synthetic linalool or linalool-AR was evaluated. The second experiment observed the behavioral effects of long-term exposure (12h) of these EOs and linalools (5 and 10 µL L-1). Fish exposed to 50-200 µL L-1 of EOAR and 100-300 µL L-1 of EOAP and both linalools reached deep anesthesia between 1-10 min. Induction time for all anesthesia stages decreased with the increasing concentration of the anesthetics. Linalool-AR showed lengthier time for anesthesia induction in some stages and for recovery at 100 and 200 µL L-1 in comparison to synthetic linalool. Normal equilibrium and swimming behavior was observed in fish exposed to the EOs and linalools throughout the 12 h of exposure. In conclusion, both EOs and linalools can be used as anesthetics and sedatives in tambaqui.

Anesthetic potential of the essential oils of Lippia alba and Lippia origanoides in Tambaqui juveniles

“…59.66% linalool). The EO of Aniba rosaeodora (EOAR), which contains 82% linalool, was faster to anesthetize tambaqui than the linalool extracted from this EO, demonstrating that some minor compounds might contribute to improving the anaesthetic efficacy of linalool EOAR (BALDISSEROTTO et al, 2018). Linalool obtained from the EO of A. rosaeodora (80% S-(+) and 20% R-(-) isomers) (BALDISSEROTTO et al, 2018) is slightly faster than EOLA-L at inducing the deep anesthesia of tambaqui, but the latter EO is more effective at inducing sedation than linalool since only 25 µL/L is necessary, compared to 100 µL/L of linalool.…”

“…Silva et al Tambaqui, Colossoma macropomum, is a freshwater fish reported in the Amazon and Orinoco River basins (SANTOS et al, 2009). It has been used as a Neotropical model to test the efficacy of anaesthetics obtained from plants (SACCOL et al, 2017;SILVA et al, 2017;BALDISSEROTTO et al, 2018;BATISTA et al, 2018). Recently, BATISTA et al (2018) demonstrated that EOLA-C was an effective anesthetic for tambaqui, but the effects of EOLA-C and EOLA-L were not compared in this species in the same experiment.…”

Aquicultura na formação dos estudantes do curso técnico integrado em agropecuária

“…Por outro lado, a aquicultura, normalmente, ocorre em um espaço confinado e controlado . Essa é compreendida pela piscicultura (BALDISSEROTTO et al, 2018), a carcinicultura (MACIEL; VALENTI, 2014), a quelonicultura (MAGNUSSON et al, 2003), a ranicultura (STÉFANI et al, 2015), a malacocultura (SAMPAIO et al, 2017), entre outros organismos aquáticos e semiaquáticos. Essas atividades são importantes tanto do ponto de vista social e econômico (SANTIAGO et al, 2018).…”

Reflections on teaching aquaculture in the Marajó archipelago, Eastern Amazon

“…The second terminology usually occurs in a confined and controlled space (Senff et al, 2018). In aquaculture we can consider fish farming (Baldisserotto et al, 2018), shrimp farming (Maciel & Valenti, 2014), the cheloniculture (Magnusson et al, 2003), the malacoculture (Sampaio et al, 2017), among other aquatic and semiaquatic organisms. These activities are important from both the social and economic point of view (Santiago et al, 2018), responsible for the continued growth in fish supply to the world's population (FAO, 2018).…”
