Scientists Test Hearing Ability of Baleen Whales for the first time

In a study published in the Science Journal, Researches Successfully Tested The Hearing of Baleen Whles for the first time. The Controversial Research, Conducted in 2023, Involved Capturing Two Juvenile Minke Whales off the Norwegian Coast. The whales, each measuring Around 12 feet and weighting approximately one ton, Were Fitted with Gold-Plated Electrodes on Their Skin to Monitor Brain Responses to Various Sound Frequences. The findings sugges that baleen whales can hear ultrasonic frequencies far higher than previous assuined, a capability believed to aid in predator evolution, particular from killars.

The project, referred to as the minke whale hearing project, has decided criticism from conservation groups and scientists. Concerns were raised Regarding the stress and potential harm caused to the whales during their temporary captivity. The whale and dolphin conservation sent open letter to the Norwegian government in 2021 urging the project’s cancellation, as per an nbc news ReportCritics Argued that Alternative, Non-Invasive Methods Cold Yield Similar Findings without rising the welfare of the animals.

Despite option, the research was executed under stringent protocols, according to brandon soutall, a marine acoustic consultant said to nbc news. He noted that the project adhered to best practices and contributed Valuable Insights Into Ocean Noise Management Policies under regulations like the Marine Mammal Protection Act.

Methodology and challenges in whale capture and testing

To facilitate testing, a complex trapping system was estimated along the minke whales’ migration route near norway’s lofoten islands, as per the studyThe team utilized over a mile of nets to guide the whales into a channel, where they were briefly help in a fish farm enclosure. Monitoring was conducted by a team of 12–15 personnel, including veterinarians. Blood Samples, Satellite Tags, and Neurological Data were collected during Sessions Lasting 30 to 90 Minutes Before the Animals were released.

Lead Researcher Dr Dorian Houser, National Marine Mammal Foundation, Emphahsized The Welfare Measures in Place during the interview with NBC News. He reported that tagged whales resumes normal behavioors post-resume, but one whale not tested die after after getting entangled in a network a story.
