Backlash against frightening tests on whales

Backlash against  frightening  tests on whales
Science
The goal is to use huge nets to drive 12 young minke whales into a holding pen - and local observers have confirmed that everything seems ready.

According to the Norwegian Food Safety Authority, the official body that s authorised the project, each whale will be held for up to six hours.

They will undergo blood tests and have electrodes fitted under their skin to measure their hearing.

"If necessary," the statement says, "the whales will be sedated".

But the authority says that based on the evidence of what happens when minke whales are caught in nets, it expects the animals to "lie completely still" until they are released.

It says, "there is no question of exposing them to loud noise but of finding the lowest noise that they can actually hear".

Before being freed, the whales will have satellite tags fitted to their dorsal fins so their behaviour after the experiments can be monitored.

It is officially acknowledged that the whales will experience pain, particularly while they are held between two rafts while their hearing is tested.

The Norwegian Food Safety Authority judges that the severity of the experiment will be "moderate" and it defines what that means: "Animals are likely to experience short-term moderate pain, suffering or distress, or long-lasting mild pain, suffering or distress," it said.

It also said that "moderately severe" experiments of this kind "are likely to cause moderate impairment of the well-being or general condition of the animals".

But it concludes that by learning more about how noise pollution disturbs marine animals, the research will benefit minke whales and other species - so it should go ahead.

In a letter to the Norwegian prime minister, the 50 scientists who object to the plans dispute the assessment about "moderate distress and discomfort".

"We believe this is an understatement," they say.

"This process risks causing the whale considerable stress leading to panic, creating a dangerous situation for both whales and humans."

The scientists believe that it s not acceptable to expose young minke whales to the risks of sedation.

"Our concern is that the capture of juvenile minke whales, forcible restraint and experimentation upon them for a period of up to six hours, has significant potential for causing injury and stress, potentially resulting in long-term impacts…"

And they are calling for the project to be cancelled because it may lead to "considerable trauma for the whales targeted, without contributing to useful science".

One of those who signed the letter is Sarah Dolman, policy manager at Whale and Dolphin Conservation.

She told me that while the threat of noise pollution is underestimated - and has been repeatedly linked to mass strandings of whales - it can t trump ethical and welfare concerns for the whales.

"They ll be herded into an unnatural environment, surrounded by human beings, and held in place.

"I think it will be incredibly stressful and incredibly frightening so we want it stopped - the situation is just too risky."

Ms Dolman points that out that similar research in Iceland was carried out on a pair of white-beaked dolphins but a female became so stressed that she had to be released.
