North Atlantics greatest survivors are hunted once more

One of the more hopeful ecological stories of recent years – the slow restoration of numbers of the North Atlantic right whale – has taken a disastrous turn for the worse. Marine biologists have found their population has plunged abruptly in the past few years and that there may now only be around 100 reproductively mature females left in the sea. Many scientists fear the species could soon become the first great whale to become extinct in modern times.

The principal cause for the North Atlantic right whale’s precipitous decline has been the use of increasingly heavy commercial fishing gear dropped on to the sea bed to catch lobsters, snow crabs and hogfish off the east coast of North America. Whales swim into the rope lines attached to these sea-bed traps and their buoys and become entangled. In some cases hundreds of metres of heavy rope, tied to traps weighing more than 60kg, have been found wrapped around whales. “We have records of animals carrying these huge loads – which they cannot shake off – for months and months,” said Julie van der Hoop, of Aarhus University in Denmark.

“This year turns out to have been catastrophic for right whale losses,” said Ann Pabst, of the University of North Carolina in Wilmington. “We know of at least 16 right whales that were killed from entanglement, and there could be more that we haven’t found about yet.”

An example of the tribulations suffered by right whales is provided by the story of Ruffian, a 13-year-old male who was discovered entangled in 138 metres of rope and a 61kg snow crab trap, which he had dragged from Canada to Florida over a period of several months. He was eventually freed by divers from the Georgia Department of Natural Resources. “I am surprised Ruffian survived given the calories he had lost in dragging around that weight,” said van der Hoop.
