In a breakthrough for marine science, researchers have recorded the largest predation event ever observed. Captured off Norway’s coast, this monumental feeding frenzy saw around 2.5 million Atlantic cod devouring more than 10 million capelin within a matter of hours.
According to Oceanographic, this rare predation was documented by a team of Norwegian and MIT scientists, who used advanced underwater acoustic technology, specifically the Ocean Acoustic Waveguide Remote Sensing (OAWRS) system.
“This is happening over a monstrous scale,” explained MIT ocean engineer Nicholas Makris. By sending sound waves that reflect off fish, the team created a real-time map of the interaction, allowing them to identify individual species.

EU tax-to-GDP ratios revealed: Where citizens pay up to 45.6% Makris noted, “Cod have large swim bladders that have a low resonance, like a Big Ben bell, whereas capelin have tiny swim bladders that resonate like the highest notes on a piano.”
Atlantic cod feasting on capelin is a natural phenomenon The event itself was dramatic but likely a regular occurrence in marine ecosystems, although it has never before been captured on such a large scale. Capelin, which usually gather in vast shoals during February to spawn, attract Atlantic cod, their primary predator.
While this event involved just 0.2 per cent of the capelin population, scientists warn that declining fish populations, especially in species like Atlantic salmon, may not recover from such events in the future if climate change persists.
The threat to the ecosystem Makris remarked, “When a population is on the verge of collapse, you will have that one last shoal. And when that last big, dense group is gone, there’s a collapse.”
This research is a reminder of the risks facing the world’s oceans, where over 97 per cent of migrating fish species, including economically valuable species, are at risk of extinction.
As climate change continues to push species out of traditional habitats, understanding these predator-prey relationships could be crucial to conserving vulnerable fish populations along Norway’s coast and beyond.
Orcamon, man.
Maybe you can play the Sea Bass,
but can you play the bouillabaisse?
Now we’e in a fine kettle of fish.
I was wondering why there was a capelin fish sandwich shortage at McDonalds...
Don’t be fooled by the scientists’ sophisticated-sounding techniques.
Off the coast of Alaska, such recording skills are commonplaice, nothing to puff themselves up about, bassically like shooting fish in a Barrow.
LOL....It’s always the Bass Player that ends up in the soup.
((((Or has to be torched out of an unopened pod. I think the Spinal Tap Stage Manger did that on Porpoise.))))
This guy's a phony, Cody. This is trout country. There ain't bass for a hundred miles.
Life is harsh. Do these Capelin expect to be coddled?
When I do, I just practice my scales.
😄
The cod feeding frenzy is nothing compared to the solid wall of Big Ladies with wigs and weaves huddled around the crab legs at the Chinese Buffet on a Friday night. They hang out there waiting for the next tray to come out of the kitchen and then pounce to fill their plates. Nothing is left except a few skinny white guys picking over the couple of remaining empty broken shells.
