White Sturgeon - Juvenile
White sturgeon are a very unique fish. They are a long lived fish (recorded up to 160 years) and are found in the Pacific Northwest from the Columbia River basin up to Alaska. They can grow to several meters and weigh several hundred pounds or even more! They are the largest freshwater fish in North America.
This juvenile was captured in one of our hoopnets that we are using to sample the local burbot population on the Kootenai River in North Idaho. Even though this fish is not a target species for the burbot project, there is a sturgeon project as well. This specific fish is most likely 2-3 years old. This sturgeon has a PIT tag (similar to tags some people put in their pets in case they get lost) that emits a small frequency that can be picked up by a specialized tag scanner. We can scan the tag and look into a database that shows if and when and where it was previously caught and how big it was then. Pretty cool stuff!
