Abstract Nutritional strategies focused on the use of phytochemicals as modulators immunological and physiological responses, well antistress antioxidant therapies health promoters gastrointestinal tract have attracted increased interest in animal production. Over past two decades, several studies reported positive results using plant essential oils ( EO s) dietary additive farm species. Recently, these nutritional alternatives been evaluated fish production order to enhance resistance...
O jundiá, Rhamdia quelen, é encontrado desde o centro da Argentina até sul do México, e seu cultivo está aumentando no Brasil. Portanto, objetivo desta revisão apresentar os dados existentes momento sobre a biologia dessa espécie. R. quelen pode atingir 50cm de comprimento 3kg peso, possui hábito noturno habita locais calmos profundos dos rios. Os alevinos suportam água mar 10%o, 9,0g/l sal comum pH na faixa 4,0 8,5, com melhor crescimento das larvas 8,0 8,5. É uma espécie euritérmica. Esse...
In aquatic environments, heavy metals are produced from natural and anthropogenic sources the degree of contamination in fish tissues depend on pollutant type, species, sampling site, trophic level, their mode feeding. The metal concentration (Al, As, Cd, Co, Cr, Cu, Fe, Mn, Zn, Pb) water, sediment, liver two species (Oligosarcus spp. – carnivore Chyphocarax voga detritivore) was analyzed at sites Sinos River, Brazil, during four seasons. highest observed followed by lowest fish. As sediment...
Responses to anaesthesia with essential oil (EO) of Aloysia triphylla (135 and 180 mg L−1) tricaine methanesulfonate (MS222) (150 300 were assessed in silver catfish. Exposure the anaesthetics elicited a stress response species. In case MS222, it was displayed as release cortisol into bloodstream, elevation hematocrit plasma ion loss. The EO presented cortisol-blocking properties, but increased haematocrit disturbances hydromineral balance observed. Liver antioxidant/oxidant status...
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...

The aim of this study was to evaluate the anesthesia induction and recovery times sub-adult post-larvae white shrimp (Litopenaeus vannamei) that were treated with eugenol essential oils (EOs) from Lippia alba Aloysia triphylla. Oxidative stress parameters in hemolymph species also analyzed. concentrations eugenol, A. triphylla EO L. recommended for 200, 300 750 μL L(-1) sub-adults 175, 500 post-larvae, respectively. studied during transport between 20 50 20-30 L(-1)A.

There is an increasing demand for inexpensive and safe anesthetics that can reduce fish stress caused by some procedures such as capture handling. In this context, the present study evaluated potential of essential oils (EO) three Brazilian native plants (Hesperozygis ringens, Lippia sidoides Ocotea acutifolia) silver catfish - Rhamdia quelen. Moreover, analysis was made chemical composition these their influence on parameter. EO H. ringens O. acutifolia were effective anesthetics, without...
