Artifical Kelp Forests Have Major Impact Artificial kelp forests were covered with real kelp just four months after researchers placed them in the Melkøy Sound in Northern Norway. The researchers also observed great amounts of cod and pollock fry around the units.
Researchers Are Using Catfish to Combat Sea Urchins In the north of Norway, researchers are now transferring catfish in an attempt to combat the sea urchin and its overgrazing of the kelp forests along the Norwegian coast. Overfishing of the sea urchins' natural predators, such as the catfish, has led to the sea urchins consuming almost 5000 km2 of kelp forests since the 1970s.
