Two huge whales have tragically washed up dead on different locations along the Scottish coastline in recent weeks, with experts concluding that the cause of death for both was rope entanglement. The first whale, a massive 9.60m long female humpback, was initially spotted floating in the Firth of Forth on September 29. A week later, a 5.75m long female minke whale was found washed ashore in Johnshaven on the Aberdeenshire coast, 100 miles north of the initial sighting.
The Scottish Marine Animal Strandings Scheme (SMASS) conducted investigations into the deaths of these majestic creatures using tissue samples and detailed images of the carcasses. Based on their findings, SMASS has expressed confidence that both whales perished as a result of rope entanglement. These cases underscore the pressing welfare and conservation issues arising from entanglement in floating rope in Scottish waters, raising the annual count of entanglement incidents to 12.
The examination of the humpback whale revealed skin abrasions consistent with rope entanglements, indicating a distressing encounter with marine debris. The minke whale, on the other hand, exhibited more severe signs of entanglement, including deep lacerations around the tailstock caused by tensioned rope that had deeply embedded into the tissue. These distressing details suggest a harrowing experience for the whale before its untimely demise.
The SMASS team highlighted the challenges in conducting complete necropsies on the whales due to access and disposal constraints. Despite these limitations, the organisation managed to gather crucial information through volunteer efforts, resulting in a clearer picture of the entanglement issues faced by marine wildlife in Scottish waters. The absence of remaining materials attached to the whales complicates the identification of the exact origins of the ropes involved.
Entanglement represents a prevalent threat to marine life in Scottish waters, with entanglement being the most commonly diagnosed cause of death in species like minke and humpback whales. The recent cases serve as poignant reminders of the urgent need to address entanglement risks and protect vulnerable marine populations. By raising awareness of these tragic incidents, conservation efforts can be further galvanised to safeguard the marine environment for future generations.
