Product Description

This is a specimen collected as part of a Museum research project studying the population of this small fish species in Nueltin Lake, a remote waterbody in the northwest part of the province and straddling the border with Nunavut. Three-spined sticklebacks are usually found only near the coast of Hudson Bay, but the Nueltin Lake population is separated from other populations by over 300 kilometers. Although it looks much the same as its marine cousins, genetic studies reveal that it is very different. The Nueltin Lake population probably was trapped and separated about 7000 years ago as the glaciers melted back during the last ice age, and the land rebounded, keeping the lake fish from access to Hudson Bay and other stickleback groups.
