Saving Endangered Whales At No Cost
Science Daily — By comparing the productivity of lobster fishing operations in American and Canadian waters of the Gulf of Maine, researchers have identified ways in which cost-saving alterations in fishing strategies can substantially reduce fishing-gear entanglements of the critically endangered North Atlantic right whale [see also here and here].
The findings appear in the January 9th issue of the journal Current Biology, published by Cell Press, and are reported by Ransom Myers of Dalhousie University in Nova Scotia, along with colleagues there and at the University of Rhode Island, the Woods Hole Oceanographic Institution, and the University of New Hampshire.
