Occurrence of killer whales in Norway is linked to the migration of the herring population with most sightings during wintertime.
Here we describe the first record of North Atlantic killer whales feeding on Atlantic salmon inside a fjord in northern
Norway during summertime, thus adding an important factor in understanding the feeding ecology of North Atlantic killer

Whale Watching Guidelines (H. Vester & R. Eriksson, Ocean Sounds & WWF Norway, 2007):
With our 5 years research experience and the help of the WWF Norway, we created a leaflet with new whale watching guidelines. Whale watching in Norway is totally unregulated and there is a need of regulating the boat traffic and human activities around the whales. Whales and whale watching boats are often disturbed by the presence of many boats or boats that drive irresponsible. Please use our guidelines, distribute them and if you go on whale watching tours in Norway, show them to your skipper and guide and ask them to follow it. If you are interested please send us an email: email@example.com
