An alternative, low‐cost method to chill water for critical thermal minima trials

Abstract

Water temperature is the most important abiotic factor to impact the physiological processes of fish and determine their distributions

Critical thermal minima of alligator gar ( Atractosteus spatula , [Lacépède, 1803]) during early life stages

“…An alternative, low‐cost way to cool water was used for our CT min trials, detailed in Bartnicki et al. (2021). In brief, we used an EcoPlus 396 water pump (Hawthorne Gardening Co.) to pass aquarium water through a series of copper tubes housed inside a cooler.…”

“…Once CT min trials were ready to be conducted, we selected multiple alligator gar from each acclimation holding aquaria and placed the gar into similar temperature experimental aquaria. An alternative, low-cost way to cool water was used for our CT min trials, detailed in Bartnicki et al (2021).…”
