“…Recently, Pottinger (2017) raised an issue that possibly ammonia, nitrate and nitrite influence the function of the stress axis in fish, alone or in combination. Similar to reports of Zeppenfeld et al (2014), the ammonia excretion in this study increased after 4 hours of transportation. According to Treasurer (2010) the density resulted in greater ammonia concentration.…”

ABSTRACT. Transportation of live fish is routinely done in aquaculture; therefore, the aim of this study was to analyze the water quality and survival rate of Rhamdia quelen fry (2.55±0.44 g) following 4, 8 and 12h of simulated transportation, at stock densities of 30 and 60 fry 5 L -1 and temperatures 15, 20 and 25 o C. Dissolved oxygen, pH, electrical conductivity, total ammonia, nitrite, nitrate, turbidity, total alkalinity and survival were analyzed. Temperature and time had a significant influence on ammonia, pH, electrical conductivity, and dissolved oxygen levels, and fish died after 12 hours of transportation simulation when kept at 20 and 25ºC. The density directly affected the water quality parameters, such as the increase in electrical conductivity and turbidity, and decrease in dissolved oxygen and pH at the density of 60 fish 5 L -1 . In conclusion, the transportation of R. quelen fry should be carried out at temperatures between 15 and 25°C, for periods of less than 12 hours, and at stock density of up to 6 fish per liter of water so as not to impair the homeostasis of the fry, and consequently, their survival.Keywords: aquaculture; ammonia; loading densities; management; mortality.Qualidade de água e sobrevivência de alevinos de Rhamdia quelen submetidos a transporte simulado em diferentes densidades e temperaturas RESUMO. O transporte de peixes vivos é uma prática comum na aquicultura. Por isso, o objetivo do presente trabalho foi analisar a qualidade de água e sobrevivência de alevinos Rhamdia quelen (2,55±0,44 g) seguindo 4, 8 e 12h de transporte simulado, em densidades de 30 e 60 peixes 5 L -1 e em temperaturas de 15, 20 e 25 o C. Foram analisados: oxigênio dissolvido, pH, condutividade elétrica, amônia, nitrito, nitrato, turbidez, alcalinidade e sobrevivência. A temperatura e o tempo tiveram influência significativa nos níveis de amônia, pH, condutividade elétrica e oxigênio, e verificou-se mortalidades após 12 horas de simulação de transporte nos peixes mantidos a 20 e 25ºC. A densidade influenciou diretamente nos parâmetros de qualidade de água, tais como o aumento da condutividade elétrica e turbidez e a diminuição de oxigênio dissolvido e pH na densidade de 60 peixes 5 L -1 . Em conclusão, recomenda-se o transporte de alevinos de R. quelen em temperaturas entre 15 e 25°C, em períodos inferiores a 12 horas. E a densidade de seis peixes por litro de água não compromete a homeostase dos alevinos, e consequentemente sua sobrevivência.

“…When stress is induced by this factor, fish react by consuming more energy, which impacts considerably on the maintenance of homeostasis (Park et al, 2008). Several studies have examined the effect of natural products with anesthetic properties, such as plant extracts and EOs, that coupled with their antioxidant properties are a promising alternative to traditional synthetic drugs (Guénette et al, 2007;Becker et al, 2012;Zeppenfeld et al, 2014) and can help to minimize stress effects (Azambuja et al, 2011;Toni et al, 2014;Becker et al, 2016). In addition, EOs have been recommended for fish anesthesia due to their low costs, easy accessibility, efficacy and environmental safety (Iversen et al, 2003;Cunha et al, 2011;Pedrazzani et al, 2016).…”

This study investigated the anesthetic effect of the essential oils (EOs) from the peel of Citrus x aurantium (EOCA) and Citrus x latifolia (EOCL) on silver catfish Rhamdia quelen. Fish were exposed to different concentrations of EOCA and EOCL to determine time of anesthesia induction and recovery. Induction of anesthesia was observed in all fish exposed to 400, 600 or 800 μL L−1 EOCA and 300, 400 or 500 μL L−1 EOCL. Another group of fish were exposed for 8 h to 50, 100, or 200 μL L−1 of either EOs. Overall, fish exposed to ethanol and both EOs presented higher ventilatory frequencies (VF) than the control group throughout the 8 h of exposure. Net ion (Na+, K+ and Cl−) effluxes and ammonia excretion were significantly lower in fish exposed to 50, 100 or 200 μL L−1 of either EOs compared to control fish. Mortality was 37% in fish exposed to 200 μL L−1 of either EOs after 8 h. These findings suggest that EOCA and EOCL are useful anesthetics and sedatives for Rhamdia quelen, but their usefulness as alternatives to reduce stress in fish transportation at the lower concentrations tested (50-100 µL L−1) deserves further study.
