Saving endangered whales at no cost

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. 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.

Though it has been protected for more than 70 years, the North Atlantic right whale has been slow to recover from past exploitation, and extinction remains a threat. The whale is virtually extinct in Europe, but a small population of about 350 individuals remains on the east coast of North America. A leading threat to the species is lethal entanglement by fishing gear: Photographic evidence indicates that 75% of individuals show signs of entanglement, mostly from lobster fishing gear.

In the new work, the researchers analyzed the costs and benefits of two dramatically different lobster fishing strategies currently employed in the Gulf of Maine, the world's most important lobster-producing area. Compared to lobster fishing on the Gulf's Canadian side (known as Lobster Fishing Area 34), which occurs over a winter fishing season, American-side lobster fishing is year-round, and involves 89 times more lobster traps in the water at any given time. Despite these significant differences in fishing "effort" and cost, Maine has only about 30% higher catches than the Canadian Fishing Area. Accordingly, the researchers estimate that the number of traps used in Maine is 13 times greater than in the Canadian Fishing Area to harvest the same lobster catch. On the basis of these findings and estimations of seasonal whale presence determi
