“…The design was organized into six treatments and three replicates for 15 days, under the following experimental conditions: low water hardness (50 mg CaCO 3 L -1 -LWH) or high water hardness (120 mg CaCO 3 L -1 -HWH) at water pH of 5.5 (acidic), 7.5 (circumneutral) or 9.0 (alkaline) according with Copatti et al (2019). Experiments were run with catholyte pH automatically controlled (Tekna TPR 603, USA) via feedback by using 50% NaOH or 98% H 2 SO 4 (Copatti et al, 2011a).…”

“…The relationship between water pH and hardness influences fish development and welfare (Baldisserotto, 2011;Copatti et al, 2011a,b). Water hardness and pH are interrelated water quality parameters and they present profound effects on fish productivity and physiology and therefore deserve special attention (Copatti et al, 2019). Hardness is important since the dissolved minerals (more specifically calcium and magnesium) are essential in the biological processes of aquatic animals, for example, bone and scale formation in fish (Guerreiro et al, 2004;Canario, Flik, 2007).…”

“…Pacu (Piaractus mesopotamicus (Holmberg, 1887)) is a Neotropical Freshwater Characin native to the Paraná, Paraguay and Uruguay basins with herbivorous/omnivorous habits, and is widely cultured in fish farms in South America (Valladão et al, 2016). A recent study found that high water hardness (HWH) has a protective effect on pacus exposed to acid or alkaline waters because HWH improved biochemical and physiological variables (Copatti et al, 2019). However, the oxidative stress (thiobarbituric acid reactive substances (TBARS), glutathione-S-transferase (GST) and total antioxidant capacity against peroxyl radicals (ACAP)) and ATPase responses (NKA and V-ATPase) to variations in water pH and hardness are still unknown for pacu.…”

This study aimed to assess the effects of low and high water hardness in interaction with different water pH in pacu (Piaractus mesopotamicus). Pacu juveniles were subjected to low (50 mg CaCO3 L-1 - LWH) or high water hardness (120 mg CaCO3 L-1 - HWH) at water pH of 5.5 (acidic), 7.5 (circumneutral) or 9.0 (alkaline) for 15 days. Gills and kidneys were collected (days 1, 5 and 15). Gill Na+/K+-ATPase (NKA) and vacuolar-type H+-ATPase (V-ATPase) activities were higher in alkaline pH with HWH on day 1. Gill and kidney NKA and V-ATPase activities were higher in acidic pH with LWH on day 15. Gill NKA activity of pacus under alkaline pH with LWH was higher than those exposed to HWH. Reduced antioxidant capacity in the gills and kidney and enhanced thiobarbituric acid reactive substances (TBARS) levels were demonstrated in fish exposed to acidic or alkaline pH, mainly with LWH. HWH increased glutathione-S-transferase (GST) activity and reduced TBARS levels in the gills and kidney. On day 15, GST activity was increased at acidic pH with LWH. In conclusion, circumneutral pH presents less oxidative stress and fewer variations in ATPases and HWH reduced deleterious effects in fish exposed to acidic or alkaline pH.

“…Blood responses of fish are an attempt to maintain the cell status (Copatti, Baldisserotto, Souza, & Garcia, 2019). Similarly, in Cyphocharax abramoides , another hypoxia‐tolerant fish, it was verified that most of the oxidative damage occurs during hypoxia not during re‐oxygenation (Johannsson et al., 2018).…”

Pacu (Piaractus mesopotamicus) lives in tropical and subtropical regions of South America, mainly in the Plata Basin and the Pantanal. Pacu can survive under conditions of low dissolved oxygen (DO), being considered a hypoxia-tolerant fish (Rocha-Santos et al., 2018). In Pantanal ecosystems, pacu migrates to smaller streams, channels and floodplains during the flood season. After the floods recede, many of them remain behind in shallow lakes and basins which can extend for miles, where the amount of DO may vary from hypoxia to normoxia (Cunha Bastos et al., 2007). In addition, the natural habitat encompasses a wide range of temperatures from 12 to 32°C
