A new study has revealed that heat-stressed fish embryos can cause physical stress in nearby embryos. The study, published in Nature Communications Biology, found that the exposure of embryos to elevated temperatures can cause nearby embryos to develop more slowly and have physical signs of stress. This could have implications for species of fish that inhabit ocean areas with rising temperatures due to climate change.

In the study, researchers exposed some embryos to temperatures of 28.5°C, which is higher than the normal temperature of 25°C, and found that the nearby embryos (not exposed to the higher temperature) developed more slowly and had physical signs of stress. The researchers also found that this stress was due to the release of molecules from the stressed embryos, which affected the development of the nearby embryos.

This study shows that heat-stressed fish embryos can cause physical stress in nearby embryos, which could have implications for species of fish in ocean areas with rising temperatures due to climate change. It is important to further study the effects of temperature on fish embryos in order to understand the consequences of climate change on marine ecosystems.
