Most whale species have increased in numbers during the past decade. During mid-late 2014 and into 2015 there have been numerous reports of hundreds of pilots whales in Norwegian Fjords.
The whale populations are increasing amid anthropogenic activity such as fishing, Navy exercises, pipeline installations and oil and gas seismic activity.
Some Norwegian fishermen are concerned about a potential reduction in fish stocks that are the prey of the pilot whales.
