Federal officials are considering expanding speed-restrictions and no-fishing zones in the Gulf of St. Lawrence after the deaths of six North Atlantic right whales in the last month.

Fisheries Minister Jonathan Wilkinson says his department is looking at what further actions can be taken to protect the endangered species in Atlantic Canada waters.

According to a federal study, measures taken so far to protect North Atlantic right whales from being struck by ships and getting caught in fishing gear may not be enough.

The study says speed restrictions and fishing-zone closures in the Gulf of St. Lawrence have lowered risks faced by the endangered whales, but dangers remain -- especially in the waters outside protected zones.
