“…Most studies related to extreme pH refer to the lethality. Although there are many studies investigating the behavior of fish in relation to environmental factors and water quality, studies relating effects of water pH and behavior are scarce (JONES et al, 1985;IKUTA et al, 2003;SCOTT et al, 2005) and nonexistent in Brazilian native species. Therefore, the objective of this study was to evaluate silver catfish preferred pH.…”

“…Sockeye salmon (Oncorhynchus nerka), brown trout (Salmo trutta) and Japanese trout (Salvelinus leucomaenis) showed inhibition of digging and swimming behavior against the flow in water slightly acidic (5.8-6.4) compared to neutral pH (6.8-7.1) (IKUTA et al, 2003). Juvenile brook trout (Salvelinus fontinalis) were given the choice of untreated (pH 7.4) or decarbonated acidic waters at varying pH levels (4.0, 5.0, 5.5, and 6.0) for 96 hours.…”

“…Japanese fat minnows (Phoxinus lagowski) presented avoidance behavior and their swimming region shifted from pH 6.0 to 7.0 immediately after decreasing pH and during the exposure to acidic water their swimming activity clearly decreased (Nakamura, 1986). Sockeye salmon (Oncorhynchus nerka), brown trout (Salmo trutta) and Japanese trout (Salvelinus leucomaenis) showed inhibition of digging and swimming behavior in slightly acidic (5.8-6.4) compared to neutral water (6.8-7.1) (Ikuta et al, 2003). Juvenile brook trout (Salvelinus fontinalis) avoided pH 4.0, 5.0 and 5.5 and these acidic pH values affected social interactions (Pedder & Maly, 1986).…”

“…The usual pH range for fish growth is 6.0 to 9.0; lower pH can occur due to the presence of acidic cations, humic and fulvic acids, and more alkaline pH can be due to high levels of carbonate and other ions (Parra & Baldisserotto, 2007). Water quality may elicit a preference or avoidance response in fish (Kroon & Housefield, 2003), and several studies have demonstrated that fish preferred a specific pH (Jones et al, 1985;Nakamura, 1986;Peterson et al 1989;Åtland & Barlaup 1996;Åtland, 1998;Ikuta et al, 2003;Kroon & Housefield, 2003, Kroon, 2005, Scott et al, 2005, Riffel et al, 2012.…”

Preference behavior of silver catfish, Rhamdia quelen, juveniles in waters with pH gradients: laboratory experiments

The aim of this study was to determine the preferred pH in silver catfish Rhamdia quelen juveniles acclimated to different water hardness and the effect of shelters and infection by Ichthyophthirius multifiliis. Fish were acclimated for two weeks at different water hardness levels (4, 24, 50, or 100 mg CaCO 3 L -1) and then transferred to a polyethylene tube with a pH gradient ranging from 3.5 to 11.7 and maintaining the same hardness. The position of the fish in the pH gradient was observed at 1, 2, 4, 6, 8, 10, and 12 h after transfer. Acclimation to different water hardness did not change pH preference of uninfected silver catfish (pH 7.30-7.83), and the presence of a shelter at the preferred pH or outside this preferred pH did not change the chosen pH range, either. Consequently silver catfish favored the acid-base regulation over shelter seeking tendency. Juveniles infected with I. multifiliis acclimated to water hardness of 24 mg CaCO 3 L -1 preferred alkaline pH (9.08-9.79). This choice is not explained by the higher Na + levels at alkaline pH compared to neutral pH because infected and uninfected fish choose the same waterborne Na + levels in a Na + gradient with the same pH.O objetivo deste estudo foi determinar o pH preferencial de juvenis de jundiá Rhamdia quelen aclimatados a diferentes durezas da água e o efeito de abrigos e infecção por Ichthyophthirius multifiliis. Os peixes foram aclimatados durante duas semanas em diferentes níveis de dureza da água (4, 24, 50 ou 100 mg CaCO 3 L -1 ) e então transferidos para um tubo de polietileno com um gradiente de pH de 3,5-11,7, mantendo a mesma dureza. A posição do peixe no gradiente de pH foi observada 1, 2, 4, 6, 8, 10 e 12 h após a transferência. A aclimatação a diferentes durezas da água não afetou o pH preferencial de jundiás não infectados (pH 7,30-7,83), e a presença de um abrigo no pH preferido ou fora deste pH também não alterou a faixa de pH preferida. Portanto, jundiás favorecem a regulação ácido-base em detrimento a uma tendência de procurar abrigo. Em juvenis infectados com I. multifiliis aclimatados à dureza da água de 24 mg L -1 de CaCO 3 o pH preferencial é alcalino (9,08-9,79). Esta escolha não é explicada pelos maiores níveis de Na + em pH alcalino que em pH neutro porque peixes infectados e não infectados escolheram os mesmos níveis de Na + na água em um gradiente de Na + com o mesmo pH.

“…Anthropogenic acidification of lakes and rivers can have dramatic and far‐reaching implications for the structure and function of aquatic ecosystems (Ikuta, Suzuki, & Kitamura, ; Johnson & Webster, ; Leduc, Munday, Brown, & Ferrari, ; Petrin, Englund, & Malmqvist, ). Acidification occurs primarily as a result of acidified rain or snow depositions, whereby the emissions of sulphur dioxides and nitrogen oxides into the atmosphere form highly acidic precipitations that can have long‐lasting effects on freshwater pH (Galloway, Norton, & Church, ; Muniz, ).…”

The impact of water pH on association preferences in fish

Acidification of lakes and rivers, as a consequence of anthropogenic interference, can cause fundamental changes to biological and ecological processes. One of the main consequences of a reduction in water pH for aquatic organisms is the disruption of their chemosensory abilities, as the detection of chemical cues underpins a wide range of decision‐making processes; for example, a reduction to low pH has been shown to interfere with predator avoidance and the detection of foraging cues. Moreover, aquatic organisms are known to make widespread use of chemical information to inform their social behaviour, although we have a comparably poor understanding of how this is impacted by water acidification, especially their shoaling behaviour. Using a standard behavioural assay, we therefore investigated the impact of low water pH on the social interactions mediated by diet‐derived chemical cues in three‐spined sticklebacks (Gasterosteus aculeatus), by quantifying social behaviour in water that varied either experimentally or naturally in pH. In both cases, we predicted that association patterns would be disrupted by low pH conditions, as reduced pH has shown to interfere with the perception of chemical cues in other non‐social contexts. Consistent with this prediction, our results demonstrate that an acute, short‐term reduction in water pH caused a breakdown in the diet‐mediated social interaction patterns seen in more alkaline water, although, interestingly, the pattern of associations for fish tested in naturally acidic water was both more complex and in a direction that was precisely contrary to our predictions. Overall, the findings provide insights into the potential effects of an acute reduction in water pH on fish communication and social interaction patterns, which may have implication for various individual, group, population and community‐level processes.
