If there’s a more beautiful coldwater fish species than the male North American Rainbow Shiner 🌈 coming into its breeding colours then I’d love to see it! What a fish! ❤️ goes to show you really can get tropical colours away from coral reefs! Thanks to my great pals at Maidenhead Aquatics Wenvoe I’ve been talking about picking these up for months!

Coldwater fish like trout and salmon are particularly vulnerable to climate change. To help protect these vulnerable species, scientists created a tool that uses NASA satellite imagery and other data to monitor fish habitats and assess extinction risk. Learn more about the tool and how the U.S. Fish and Wildlife Service and others are using it to protect these species as our planet warms. | NASA Climate Change
