1. Essential oils of Cunila galioides and Origanum majorana as anesthetics for Rhamdia quelen: efficacy and effects on ventilation and ionoregulation
RESUMO No presente estudo foi avaliada a eficácia da anestesia e possíveis efeitos dos óleos essenciais (EOs) de Cunila galioides (EOC) e Origanum majorana (EOO) sobre a taxa ventilatória (VR) e regulação iônica em Rhamdia quelen. Nas avaliações de anestesia, as concentrações de 50, 100, 200 e 300 μL L-1 EOC e 50, 100, 200, 300, 400 e 500 μL L-1

2. Effect of humic acid on survival, ionoregulation and hematology of the silver catfish, Rhamdia quelen (Siluriformes: Heptapteridae), exposed to different pHs
This study evaluates whether humic acid (HA; Aldrich) protects the silver catfish, Rhamdia quelen (Quoy & Gaimard, 1824), against exposure to acidic pH. Survival, levels of Na+, Cl- and K+ plasma, hematocrit, hemoglobin and erythrocyte morphometry were measured. Fish were exposed to 0, 10, 25 and 50 mg L 1 HA at four pH levels: 3.8, 4.0, 4.2 and 7.0 up to 96

3. EFEITO DO CLORETO DE SÓDIO NA DIETA, DUREZA E pH DA ÁGUA NA SOBREVIVÊNCIA, CRESCIMENTO E FLUXOS IÔNICOS DE JUVENIS DE JUNDIÁ (Rhamdia quelen) / EFFECT OF DIETARY SODIUM CLORET, WATER HARDNESS AND pH ON SURVIVAL, GROWTH AND IONIC FLUXES OF SILVER CATFISH (Rhamdia quelen) JUVENILES
The purpose of this study was to verify the effect of dietary salt (NaCl) supplementation, water hardness and pH on growth, survival and ionoregulation of silver catfish (Rhamdia quelen) juveniles. In the first experiment, juveniles were fed with diets supplemented with 0.0; 0.5; 1.0 e 2.0 % NaCl and exposed to pH 5.5, 7.0 and 9.0 for 35 days. In the second
