          Abstract

          Se evaluó el uso de la tricaína (MS-222) como agente sedante para uso en el transporte de Anisotremus scapularis juveniles . Para ello, se realizó un transporte simulado de 24 horas a dos temperaturas (15 y 19 °C) usando concentraciones del anestésico de 0, 15, 20 y 25 mg.L-1 en bolsas de polietileno (50% agua de mar 50% oxígeno puro). Se monitoreó, tanto al inicio como al final de la simulación, la temperatura, saturación de oxígeno disuelto, pH y tasa de excreción individual de amonio. En los peces se evaluó la pérdida de equilibrio (%) y sobrevivencia (%) al término de la simulación y luego de un tiempo de recuperación de 24 horas adicionales. Los resultados muestran que el uso de tricaína favorece la disminución de la excreción de amonio; sin embargo, dosis superiores a 20 mg.L-1 de tricaína incrementan considerablemente la pérdida de equilibrio. Además, el efecto de sedación es más intenso a temperaturas más bajas (15 °C). Por otro lado, el pH del agua se ve afectado mostrando una disminución promedio de 1.44 durante la simulación del transporte en todos los tratamientos. Con base a los resultados se recomienda el transporte de juveniles de chita a 19 °C con uso de tricaína a 15 mg.L-1

          Translated abstract

          The use of tricaine (MS-222) as sedative agent for transporting of Anisotremus scapularis juveniles was evaluated. A simulated transport of 24 hours was performed at two temperatures (15 and 19 °C) using the anaesthetic concentrations of 0, 15, 20 and 25 mg.L-1 in polyethylene bags (50% seawater 50% pure oxygen). At the beginning and the end of the simulation temperature, dissolved oxygen saturation, pH and ammonia excretion rate were monitored. On fishes, the loss of balance (%) and survival (%) were monitored at the end of the simulation and after an additional recovery time of 24 hours. The results showed that use of tricaine favours the reduction of ammonia excretion, however, tricaine doses over 20 mg.L-1 significantly increase the loss of balance in fish. Furthermore, the sedating effect is magnified at lower temperature (15 °C). On the other hand, the water pH is affected showing an average decrease of 1.44 during the transport simulation in all treatments. Based on the results, transport of Peruvian grunt juveniles using tricaine in a dose of at 15 mg.L-1 at 19 °C is recommended
