Killer Jellyfish Decimate Over 200,000 Salmon Stocks in Scotland
A devastating incident has unfolded in Scotland as a jellyfish species known as the String of Pearls Jellyfish (Apolemia uvaria) has decimated over 200,000 salmon in two salmon farms. The Green Britain Foundation reported that this jellyfish species, also called string jellyfish or barbed wire jellyfish, has wreaked havoc on the salmon farming industry in Norway, killing more than three million salmon in 2023.
The attack hit the Scottish salmon farms shortly after a distressing video was released by the foundation, showing the removal of tons of salmon of various sizes just two days prior to the jellyfish strike. These jellyfish inflict excruciating burns on the salmon’s skin, eyes, and gills with their venomous tentacles, leaving the trapped fish highly vulnerable to infections and diseases, leading to slow and painful deaths if untreated.
Dale Vince, founder of the Green Britain Foundation, points to this event as a clear sign of the need for stricter regulation and oversight in the salmon farming industry. He emphasised the environmental challenges that these farms are facing and called for accountability and consequences for actions taken by these companies.
The incident serves as a warning of the economic and ecological impacts that open-net salmon farming can face due to unpredictable threats like jellyfish blooms as climate change continues to disrupt marine ecosystems. Experts are urging the phasing out of open-net farming, but until then, strict regulations and environmental safeguards must be enforced to prevent further damage.
In Norway, reports indicate an ongoing and increasing jellyfish threat to salmon farms, prompting the Norwegian Food Safety Authority to caution salmon farmers to prepare for such attacks and implement measures to mitigate the impact on their fish stocks. The authorities have highlighted the severe burns inflicted on salmon by the jellyfish, rendering them susceptible to infections and diseases.
Both environmentalists and government officials stress the importance of understanding and addressing the impact of jellyfish on salmon farming to ensure the health and sustainability of farmed fish in Scotland and beyond.
