Abstract
Hypoxia is a common occurrence in aquatic systems. In the face of increasing human disturbance and the prevalence of hypoxia, understanding how species will respond to such changes is imperative from an ecological perspective. Fish models are a useful tool for investigating cellular adaptations and oxidative stress resulting from hypoxia due to the incredible diversity observed across taxa in their response to limited oxygen availability. Here, we investigated resilience to repeated acute hypoxia stress in the highly social cichlid fish, Astatotilapia burtoni. Our results indicate that A. burtoni are a hypoxia-tolerant species, evidenced by their quick buildup of exposure tolerance and lack of increased brain oxidative stress following three consecutive exposures. Additionally, our results indicate that the relationship between mitochondrial function and reproductive investment may be modulated by acute hypoxia exposure. We are interested in continuing to investigate how reproductive investment influences bioenergetic adaptions to hypoxia in A. burtoni.
