Archaeologists found old fish traps in Norway's mountains. They discovered that hunter-gatherers introduced fish to these lakes around 5,000 years ago.
Archaeologists have made an exciting discovery in the mountains of southern Norway. They found the remains of 7,000-year-old fish traps at Lake Tesse. These traps were used by Mesolithic hunter-fisher-gatherers to catch fish.
The researchers wanted to know when these people started moving fish from their natural habitats to lakes and rivers that didn't have fish before. They radiocarbon dated the traps and found out they were in use from 5,000 B.C. onward.
This means that hunter-gatherers in Scandinavia were actively managing their environment to control their food supply. They introduced brown trout into these lakes, which are still harvested by modern fishermen today.
Why It Matters
This discovery shows how early humans interacted with and transformed ecosystems. It's a reminder of the impact we can have on our environment, even without farming or technology.
