Now a team of oceanographers at MIT has journeyed to Norway — one of the last remaining regions of the world where cod still thrive — and used a synoptic acoustic system to, for the first time, illuminate entire shoals of cod almost instantaneously, …

Atlantic cod are a shoaling species and move in large, size-structured aggregations. Larger fish act as scouts and lead the shoal's direction, particularly during post spawning migrations inshore for feeding. Cod actively feed during migration and …

2024年10月29日 · In the largest predation event ever recorded, researchers observed capelin shoaling off the coast of Norway, where a swarm of cod overtook them, consuming over 10 million fish in a few hours. The team hopes to deploy their technique to monitor the large-scale dynamics among other species of fish and track vulnerable keystone species.

2024年11月18日 · The cod, which can grow up to 1.5 meters in length and weigh up to 50 kilograms, formed their own enormous shoal in response. Using new large-scale acoustic imaging technology that maps marine environments over tens of thousands of square kilometers, the researchers observed how around 2.5 million cod consumed 10.5 million capelin within just a ...

2000年2月1日 · We use current meter data concurrent with the tracking experiment to calculate the swimming speeds and headings of tagged cod as the shoal began its migration to the Newfoundland coast. We test the hypothesis that an onshore current event provides a cue which initiates migration behavior.

2024年11月29日 · The largest shoal of cod fish ever seen is estimated to have around 10 million fish. This massive group is primarily located in the Northeast Atlantic. Alphonse Bielevich holds the record for the largest cod caught, weighing 211.25 pounds in May 1895.

2024年11月5日 · A new study details how, in just a few hours, more than 2 million Atlantic cod consumed 10 million tiny capelin. Scientists say the feeding frenzy is the largest on record, both in terms of the number of fish involved and the area covered. Each winter Atlantic cod feed on spawning capelin along the Norwegian coast.
