Norway to proceed with experiment on whales, despite protests

A analysis crew is meaning to seize a dozen juvenile minke whales off the Norwegian coast and use sensors positioned on their pores and skin to measure their mind responses in response to sound.

The analysis crew conducting the experiment says it’s designed to grasp which sorts of human-made ocean noise have an effect on the whales, as human-made sound can have an effect on an animal’s listening to and conduct and trigger it stress.

“We have essentially no knowledge of their hearing, and it’s important to noise regulators to know what kind of noise might affect them,” Petter Kvadsheim, chief scientist on the Norwegian Defence Research Establishment (FFI), advised CNN. He added that the crew will not be testing the animals’ noise tolerance, or how they reply to the sound behaviorally.

“We expose them to the lowest sound they can hear to find their hearing threshold, using electrophysiological methods developed for use on newborn children,” mentioned Kvadsheim, who’s the co-lead investigator on the experiment. He added that the experiment is ongoing.

But 50 worldwide scientists and veterinarians have referred to as on Norway’s Prime Minister to cancel the trial, writing in an open letter that the seize and size of experimentation “has significant potential for causing injury and stress, potentially resulting in capture myopathy.” Capture myopathy is a non-infectious situation in wild and home animals by which muscle injury outcomes from excessive exertion, battle, or stress, and might be deadly.

“Little is known about sedating or stunning wild whales and dolphins, and it is therefore rarely attempted. Available data indicate that sedation of baleen whales in the wild could be life-threatening,” UK-based group Whale and Dolphin Conservation (WDC), which spearheaded the letter, mentioned in a separate assertion.

“We already know a great deal from observational studies about how high-amplitude, human-made noise affects baleen whales, so the proposed research is not only dangerous and unethical, it is also redundant,” they added.

Norway’s Food Safety Authority, which authorised the trial, acknowledged that the experiment, which entails catching the whales, preserving them in an enclosure for 3-Four days, and tagging them, “involves moderate distress and discomfort for up to six hours.”

Ole Aamodt, head of the veterinary division on the Norwegian Food Safety Authority, mentioned the experiment was thought-about to have “moderate” severity.

“Procedures on animals as a result of which the animals are likely to experience short-term moderate pain, suffering or distress, or long-lasting mild pain, suffering or distress, as well as procedures that are likely to cause moderate impairment of the well-being or general condition of the animals, are classified as moderately severe,” Aamodt mentioned.

“There is nothing to indicate that this experiment should be regarded as severe,” he added.

“We assess that the purpose of the experiment is well-described and justified, and that this justifies the burden on the animals,” he mentioned.

But in an announcement of concern, the 50 worldwide scientists who signed the letter mentioned that is an “understatement,” including: “This process risks causing the whale considerable stress leading to panic, creating a dangerous situation for both whales and humans.”

More than 64,000 individuals have signed a petition calling for the experiment to be stopped.

“We have been through a very thorough planning and permitting process to reduce the risk to a minimum,” Kvadsheim advised CNN.

“We expect that the animals will experience some level of stress, but we have veterinarians monitoring their health and welfare throughout the procedure. If animals are in danger or distress they will be released,” he added.
