Part of the ALA's mission is conservation, and sometimes conservation research provides information that also aids us in fish care.

This study inadvertently demonstrates the impact on the fish gastrointestinal system when environmental temperatures are adjusted. While the effects may vary between species, we should be aware of the potential physiological changes that could occur when we adjust the temperature, or fail to provide optimum temperatures for any species.

The researchers looked at how gut function in various fish species is affected by both rapid and slow changes in water temperature, to better understand what will happen to different species when the climate changes.

"When the temperature of the water rises, the fish's body temperature climbs, activity in the gut increases, and more energy is needed to stay healthy," Gräns said. "Since changes in body temperature affect virtually all of a fish's organs, it's surprising that we know so little about how temperature changes impact on their physiology,"
