Thousands of Moon Jellyfish Blanket Dunbeath Bay
19 Jul
Summary
- A fishing trip encountered an unusually dense mass of jellyfish.
- The jellyfish swarm significantly impacted fishing yields.
- Moon jellyfish, which do not sting, were identified in the swarm.

A fishing expedition near Dunbeath, Scotland, recently encountered an extraordinary spectacle: a vast sea of moon jellyfish. Daniel Macleod and his twin sons were handline fishing for mackerel when they sailed into Dunbeath Bay and found it covered by thousands of these marine creatures.
Describing the sight as a 'dense, thick mass,' Macleod noted this was far more jellyfish than they had ever seen during previous outings. While the boat's engine cooling system remained unobstructed, the sheer number of jellyfish impacted their fishing success, resulting in a significantly reduced catch.
This occurrence is part of a broader trend of jellyfish blooms in Scotland's coastal waters during the summer months. While moon jellyfish are common and non-stinging, other species can pose a threat. Marine conservation groups encourage the public to report jellyfish sightings to aid tracking efforts.
