Native fish populations in Australian ephemeral rivers are highly valued but are subject to widespread decline. During drought waterholes serve as critical refuges for native fish, however thermal extremes and hypoxia (lack of oxygen) have led to regular fish-kill events. Whilst we know the general conditions that lead to fish-kills, we do not have a clear understanding of why some species are more tolerant than others, or how we can help decision-makers anticipate fish-kill risks. This project will combine laboratory ecophysiology investigations and novel field monitoring techniques to develop a next-generation fish habitat model for stakeholders to use to assess fish-kill risks and plan for restoration.

澳大利亚短暂河流中的本地鱼类种群受到高度重视，但会受到广泛下降。在干旱水坑中，水孔是对天然鱼类的关键避难所，但是极端和缺氧（缺乏氧气）导致了常规的鱼类杀伤事件。虽然我们知道导致鱼类杀虫剂的一般条件，但我们对某些物种为什么比其他物种更宽容，或者我们如何帮助决策者预期鱼类杀伤风险有清楚地了解。该项目将结合实验室生态生理研究和新颖的现场监测技术，以开发下一代的鱼类栖息地模型，供利益相关者用于评估鱼类杀伤风险和计划恢复。
