The aim of this study was to identify the time anesthetic induction and recovery silver catfish (Rhamdia quelen) exposed eugenol. It also determined efficacy as a stress reducing agent performed sensory analysis fillets from fish substance. were air for 1min carry out biometry, blood collected at 0, 1 4 hours later. Eugenol can be used in range 20-50mg L-1 catfish, anesthesia not affected by eugenol concentration. control group showed significantly higher cortisol levels after biometry than...

This study examined the growth, gut morphology and occurrence of endocrine cells in gastrointestinal tract silver catfish (Rhamdia quelen) fed diets supplemented with essential oil (EO) extracted from Aloysia triphylla (0 – control, 0.25, 0.5, 1.0 2.0 mL EO per kg diet) for 60 days. The group diet showed better results after days body weight, weight gain specific growth rate. Histological immunohistochemical analyses intestine demonstrated that height folds was significantly higher control...
This study evaluated extracts of Condalia buxifolia as anesthetics for the silver catfish Rhamdia quelen. The effectiveness eugenol and methanolic extract (ME) C. during transport this species was also assessed. Fish two different weights (1.50±0.02 g 165.70±22.50 g) were transferred to aquaria containing water with ME or fractions obtained from ME, such n-hexane, dichloromethane, ethyl acetate, n-butane aqueous fractions, at concentrations 0-300 °L L-1. in 0.5-120 L-1range caused only light...
Abstract The transport of live fish is a routine practice in aquaculture and constitutes considerable source stress to the animals. addition anesthetic water used for can prevent or mitigate deleterious effects stress. This study investigated eugenol (EUG) (1.5 3.0 µL L–1) essential oil Lippia alba (EOL) (10 20 on metabolic parameters (glycogen, lactate total protein levels) liver muscle, acetylcholinesterase activity (AChE) muscle brain, levels carbonyl (PC), thiobarbituric acid reactive...
Abstract Exposure of silver catfish to 40 μL/L the essential oil Aloysia triphylla (AT) during in vivo transport delayed onset and resolution rigor mortis as well degradation IMP into HxR compared control. The fish that were treated with 30 or AT received lower sensory demerit scores after 10 d storage ice control, had a longer shelf life than did These results indicated using sedative water which transported extended their freshness increased refrigerated storage.
We examined the effects of dietary supplementation for 21 days with different levels (0, 0.25 and 2.0 ml/kg) Aloysia triphylla essential oil (EOAT) on silver catfish (Rhamdia quelen). Cortisol were lower in fish fed EOAT at ml/kg diet, lactate those both doses. Glucose, alanine aminotransferase, aspartate aminotransferase triglyceride did not vary between groups. The biomarkers oxidative stress, thiobarbituric acid-reactive substances, lipid hydroperoxide, superoxide dismutase, catalase...
Pseudomonas aeruginosa is a Gram-negative opportunistic bacterial pathogen in aquaculture systems being associated to extensive liver damage caused by oxidative stress both marine and freshwater fish. Dietary supplementation with natural antioxidants considered rational strategy prevent hepatic diseases involved stress. Bio-residues resulting from the wine industry, such as grape pomace, are potential sources of bioactive phenolic compounds that can be applied supplement for animal...
The spleen is an important secondary lymphatic organ that plays a key role in the immune and inflammatory responses of teleost fish. purinergic signalling has been associated to these types under pathological conditions by regulation extracellular adenosine triphosphate (ATP) its metabolite (Ado), where both exert potent pro-inflammatory anti-inflammatory profiles, respectively. exact pathway involved on immunotoxic effects aflatoxin B1 (AFB1) fish fed with diets containing this mycotoxin...
Mycotoxins are secondary metabolites produced by varieties of fungi that contaminate food and feed resources capable inducing a wide range toxicity. This problem is extensively aggravated due to the increasing replacement fish meal plant-derived proteins. Among mycotoxins, aflatoxins have received great deal attention owing their prevalence in plant feedstuffs detrimental effects on animals. The objective this study was evaluate whether dietary supplementation with tea tree (Melaleuca...
It has been recognized that oxidative stress is implicated in the initiation and progression of diseases due to excessive formation free radicals impairment antioxidant defense system, contributing mortality affected animals. The occurrence a disequilibrium between antioxidant/oxidant status serum liver freshwater fish fed with aflatoxin B1 (AFB1) remains poorly understood limited only few oxidant variables. Thus, aim this study was evaluate whether an AFB1-contaminated diet causes...
In vitro and in vivo activity of the Lippia alba essential oil (EO) against Aeromonas sp. was evaluated. assay minimum inhibitory concentration (MIC) a bactericidal (MBC) EO for cells were determined using microdilution method. Twenty five strains isolated from infected fish obtained local farms used. MIC MBC values 2862 5998 µg mL-1 L. 0.5 1.2 gentamicin, respectively. silver catfish juveniles (Rhamdia quelen) (7.50 ± 1.85 g 10.0 1.0 cm) with typical injuries associated to infection divided...
