“These refuges are known to promote resilient and diverse aquatic ecosystems that can withstand both short-term heat waves and potentially long-term climate warming, but thermal refuges are not distributed uniformly in space,” mentioned the presentation abstract. In the active method, they introduced cold water from a well into the river. In contrast, in the passive approach, they rerouted a branch of the river underground for a distance, allowing it to cool through contact with the surrounding soil and rocks.
As the offshoot rejoined the main river channel, it formed a zone of water a few degrees cooler than the surrounding area. In both scenarios, various fish species quickly gravitated toward these artificially created cold-water locations, with the active approach attracting a more significant number of fish.
