New Study Suggests Fish Embryos at Great Risk from Warming Temperatures

July 6, 2020 By: Marshall Cutchin

According to a study published this week in the journal “Science,” both food fish and brown trout will be at severe reproductive risk as global water temperatures continue rising.

“Global warming looks like it will be a bigger problem for the world’s fish species than scientists first thought: A new study shows that when fish are spawning or are embryos they are more vulnerable to hotter water.

With medium-level human-caused climate change expected by the end of the century, the world’s oceans, rivers and lakes will be too hot for about 40% of the world’s fish species in the spawning or embryonic life stages, according to a study in Thursday’s journal Science. That means they could go extinct or be forced to change how and where they live and reproduce.”
