Oxygen consumption in relation to current velocity and morphology in the highly invasive crayfish Procambarus clarkii

Abstract: The red swamp crayfish (Procambarus clarkii) is the most widely spread freshwater crayfish worldwide. Competing physiological traits can influence invasion success in any given environment by limiting the available scope for aerobically demanding activities. While high flows have been associated with reduced crayfish movement upstream, the effects of flow alteration on their metabolic demands have been largely overlooked. In this study, we estimated routine metabolic rate (RMR) at rest and oxygen consumption r… Show more

“…However, such work will be challenging, requiring novel combinations of expertise and overcoming logistical challenges associated with the fact that zoogeomorphic work, such as burrowing, can take place in short bursts (seconds) of activity that are intermittent over longer periods of time (hours). This is in contrast to past bioenergetics work in flowing respirators that has focused more on the holding and swimming behaviours of fish and crayfish, where the time duration of a given behaviour can be controlled and is relatively consistent over periods of minutes to hours (e.g., Rubio-Gracia et al, 2022). However, if bio-energy can be measured in the field, then comparisons could also be made to more accurate estimates of flow energy, as opposed to the simplified, daily metrics used here.…”
