“…In this study, the total ammonia and NH 3 levels were much lower at the end of transport than the lethal values, but the DO levels were very low and near the lethal concentration for R. quelen (Braun et al, 2006). Additionally, exposure to high waterborne NH 3 (0.1 mg L -1 ) and low DO (3.5 mg L -1 ) levels for 6 and 24 h caused ionoregulatory changes in this species (Becker et al, 2009). Therefore, the low DO levels and high NH 3 levels found in the control treatment group may explain the increase in mortality for this group.…”

“…The net K + loss rates across the gills must have occurred in this study, since plasma levels of K decreased at the highest NH 3 concentrations. On the other hand, silver catfish exposed to 0.1 mg L -1 NH 3 for 6-24 h had higher plasma Na + , K + and Cl -levels compared to those exposed to 0.03 mg L -1 NH 3 (BECKER et al, 2009). The effects of NH 3 on plasma ion levels of freshwater fish seem to be highly species-dependent and vary according to the pH and NH 3 concentration of the water (BOLNER et al, 2014 Stressed fish are expected to increase plasma glucose and decrease glycogen levels to contribute to the increase in energy demand (BARCELLOS et al, 2004).…”

“…Lower plasma osmolality indicated that catfish acutely exposed to extreme water quality conditions exhibited an increased stress response in comparison with baseline levels and other treatments. Low osmolality values are indicative of stress induced by low DO levels (Peterson & Brown‐Peterson, ) as fish increase gill permeability and ventilation which contributes to ion losses (Becker et al, ). Gill permeability increases due to elevated intralamellar blood pressure which increases in response to higher ventilation and gill flow rates (Rosso, Bolner, & Baldisserotto, ).…”
