“…Many experimental studies test how animals respond to changes in environmental oxygen by exposing them to acute hypoxic stress. Such experiments are often combined with chronic oxygen treatments to control for longer-term effects of DO environment (Ackerly et al 2018; Ackerly et al 2023; Borowiec et al 2015; Borowiec et al 2018; Borowiec et al 2020; Collins et al 2015; Cook et al 2013; Ding et al 2013; Lomholt and Johansen 1979; Love and Rees 2002; Pan et al 2017; Prosser et al 1957; Reardon and Chapman 2010; Shang et al 2006).…”

Environmental control systems are important tools for experimental researchers studying animal-environment interactions. Commercial systems for measurement and regulation of environmental oxygen conditions are relatively expensive and can not always be adapted to varying experimental applications. Here, we present a low-cost and highly flexible oxygen control system using Arduino microcontrollers in combination with a commercial optical oxygen sensor. We show dissolved oxygen (DO) measurements from three experiments that were conducted with mormyrid fish with different DO regimes: 1) acute challenge with defined rates of DO change from normoxia (> 90% air saturation) to hypoxia (10% air saturation), 2) acute stepwise hypoxia in a shuttle-box setup, and 3) long-term hypoxia (15 % air saturation) that was maintained for eight weeks in the home tank of the fish. Overall, the microcontroller-based DO control systems produced the desired experimental conditions with a high and inter-trial correlation (Pearson’s R ≥ 0.987) and sufficient precision, except for the shuttle-box setup, where the lowest DO step of 10% air saturation could not be reached.
