ABSTRACT: The goal of this study was to investigate the sedative and anesthetic properties of essential oils (EOs) in map treefrog tadpoles (Hypsiboas geographicus) and to determine the sedation and deep anesthesia induction times as well as the recovery time. The tadpoles were exposed to one of the EOs from three plant species: Aniba rosaeodora (EOAR - 25, 50, 100 or 200µL L-1), Lippia origanoides (EOLO - 13, 25, 50, 100 or 200µL L-1), and Lippia alba (either chemotype citral [EOL-C - 25, 50, 100 or 200µL L-1] or linalool [EOL-L - 50, 75, 100 or 200µL L-1]) (n = 8 per replicate). The tadpoles exposed to 25 and 50µL L-1 EOL-C and EOL-L, respectively, were not anesthetized within 30min (the maximum time of observation), and those exposed to 200µL L-1 EOLO...

ABSTRACT: The aim of this study was to investigate the anesthetic effect of the essential oils (EOs) of Lippia alba (citral and linalool chemotypes, EOLA-C and EOLA-L respectively) and Lippia origanoides (chemotype carvacrol, EOLO-Ca) on tambaqui (Colossoma macropomum) juveniles. The tested concentrations of the L. alba and L. origanoides EOs were: 25, 50, 100, and 200 μL/L. Time required to reach the stages of sedation, deep anesthesia, and recovery, as well as ventilatory frequency, were monitored for each EO concentration. The results indicated that all EO concentrations tested induced tambaqui anesthesia and that the ventilatory frequency was altered by the EOs. L. origanoides showed the shortest time to induce sedation and anesthesia, but had long...

Citral chemotype of the Lippia alba essential oil as an additive in simulated transport with different loading densities of tambaqui juveniles Ciência Rural
Silva,Hugo Napoleão Pereira da; Souza,Rodrigo Numeriano de; Sousa,Elen Monique de Oliveira; Mourão,Rosa Helena Veras; Baldisserotto,Bernardo; Silva,Lenise Vargas Flores da.
ABSTRACT: The objective of this study was to evaluate the efficacy of the citral chemotype of Lippia alba essential oil (EOLA) as an additive in a simulated transport with different loading densities of tambaqui (Colossoma macropomum) juveniles. Simulated transport of tambaqui juveniles at three loading densities (30, 60 and 90 fish/L) was carried out either with only water (WC) or 20 μL.L-1 EOLA. Dissolved oxygen levels, pH, conductivity and temperature of the water were measured at the beginning and end of the simulated transport. Treatment with EOLA did not change survival or dissolved oxygen levels at the end of simulation. The pH of the water at the end of simulation with EOLA was lower than in that of WC but did not change with loading density. Water...

Physiological responses of Rhamdia quelen (Siluriformes: Heptapteridae) to anesthesia with essential oils from two different chemotypes of Lippia alba Neotropical Ichthyology
Souza,Carine de Freitas; Baldissera,Matheus Dellaméa; Salbego,Joseânia; Lopes,Jane Mello; Vaucher,Rodrigo de Almeida; Mourão,Rosa Helena Veras; Caron,Braulio O.; Heinzmann,Berta Maria; Silva,Lenise Vargas Flôres da; Baldisserotto,Bernardo.
ABSTRACT The aim of this study was to evaluate if Lippia alba has different chemotypes according to the chemical composition of the essential oil (EO) considering collection site, and if the EO may have different effects on blood and plasma parameters in silver catfish, Rhamdia quelen, during and immediately after anesthesia. The citral (EO-C) and linalool (EO-L) chemotypes were identified, and both presented similar anesthetic effects for silver catfish. Fish were exposed to two concentrations of each EO, which induced slow and fast anesthesia (100 and 300 µL L-1, respectively). Blood ions did not change at any time of anesthesia induction and recovery and, therefore, the electrolyte balance was not altered. Blood gases oscillated through all exposure and...

Plant essential oils against bacteria isolated from fish: an in vitro screening and in vivo efficacy of Lippia origanoides Ciência Rural
Bandeira Junior,Guerino; Souza,Carine de Freitas; Baldissera,Matheus Dellaméa; Descovi,Sharine Nunes; Silveira,Bibiana Petri da; Tasca,Caiane; Mourão,Rosa Helena Veras; Vargas,Agueda Palmira Castagna de; Baldisserotto,Bernardo.
ABSTRACT: The use of natural products, such as essential oils (EOs), is a potential novel approach to treat fish bacterial infections with a lower risk of developing resistance. There has been a number of studies reporting the activity of EOs as those obtained from the species Achyrocline satureioides, Aniba parviflora, Aniba rosaeodora, Anthemis nobilis, Conobea scoparioides, Cupressus sempervirens, Illicium verum, Lippia origanoides, and Melaleuca alternifolia against bacteria. However, there are few studies investigating the effect of these EOs against fish bacteria. Therefore, the aim of this study was to evaluate the in vitro antibacterial activity of EOs against the following fish bacteria, Aeromonas hydrophila, Citrobacter freundii, and Raoultella...

Ventilatory frequency and anesthetic efficacy in silver catfish, Rhamdia quelen: a comparative approach between different essential oils R. Bras. Zootec.
Becker,Alessandra Janaína; Fogliarini,Carine de Oliveira; Souza,Carine de Freitas; Becker,Alexssandro Geferson; Mourão,Rosa Helena Veras; Silva,Lenise Vargas Flôres da; Baldisserotto,Bernardo.
ABSTRACT This study investigated the efficacy of essential oils of Lippia alba (EOLA) citral chemotype and Lippia origanoides (EOLO) and their effects on ventilatory frequency (VF) of silver catfish, Rhamdia quelen. Fish were exposed to 50-300 μL L−1 of EOLA and 25-300 μL L−1 of EOLO to determine induction times to sedation, anesthesia, and recovery. Moreover, VF was determined in fish exposed to 5 or 10 μL L−1 of EOLA and of EOLO for 8 h. The increasing concentration of essential oils proportionally decreased sedation and anesthesia induction times. The highest EOLA concentration increased VF of fish from the control group at 1 h of exposure, but VF decreased at both EOLO concentrations after 2 h. The EOLA citral chemotype and EOLO were effective...
