Rules to protect right whales working

Canadian officials say measures taken this season to protect the North Atlantic right whales have worked.
With the summer fishing season in the Gulf of St. Lawrence drawing to a close, the Fisheries Department confirmed yesterday that not one whale has died as a result of a ship strike or fishing gear entanglement.
Those were the main causes for most of the 17 deaths last season.
The federal government imposed speed restrictions for boats, increased surveillance and a series of closures of fishing areas where right whales were spotted.
