This study investigated the efficacy of essential oils Lippia alba (EOLA) citral chemotype and origanoides (EOLO) their effects on ventilatory frequency (VF) silver catfish, Rhamdia quelen. Fish were exposed to 50-300 μL L−1 EOLA 25-300 EOLO determine induction times sedation, anesthesia, recovery. Moreover, VF was determined in fish 5 or 10 for 8 h. The increasing concentration proportionally decreased sedation anesthesia times. highest increased from control group at 1 h exposure, but both...
ABSTRACT: The use of anesthetics in aquaculture ensures better animal welfare and survival during transport the production cycle. present study evaluated anesthetic efficacy essential oils (EOs) Lippia alba (EOLA) Ocimum gratissimum (EOOG) for pink shrimp Farfantepenaeus paulensis, EOs Origanum majorana (EOO) Cymbopogon citratus (EOC) white Litopenaeus vannamei. were exposed to (i) 500, 750 or 1000 µL L-1 EOLA (ii) 50, 100, 150 250 EOOG, L. vannamei (iii) 150, 300 500 EOC (iv) 400 800 EOO....
This study evaluated the effects of continuous exposure to essential oil Cymbopogon citratus (EOC) on behavioural and biochemical parameters in shrimp Litopenaeus vannamei. Adult were randomly placed aquaria divided into following groups: control (pure seawater), ethanol (360 μl L−1 ethanol) 5 or 10 EOC for 6 h. Shrimp movements recorded using a camera min at timepoints: 0, 1, 2, 4 h exposure. Light sedation changes observed group. The total antioxidant capacity against peroxyl radicals...
Amphipods are frequently used as bioindicators of water quality in experimental or behavior trials. Thus, it is a group considered suitable for use model organism tests with essential oils (EOs). This study evaluated the time required anesthesia induction and recovery amphipod crustacean H. bonariensis exposed to Aloysia triphylla (EOAT) Lippia alba (EOLA), their major compounds citral linalool, respectively. In addition, we locomotor activity amphipods using ANY-maze® software. Mortalities...
The aim of this study was to determine the preferred pH in silver catfish Rhamdia quelenjuveniles acclimated different water hardness and effect shelters infection by Ichthyophthirius multifiliis. Fish were for two weeks at levels (4, 24, 50, or 100 mg CaCO3 L-1) then transferred a polyethylene tube with gradient ranging from 3.5 11.7 maintaining same hardness. position fish observed 1, 2, 4, 6, 8, 10, 12 h after transfer. Acclimation did not change preference uninfected (pH 7.30-7.83),...
