A colony that occupies the area of Malta
"We covered an area of 45,600 square meters and counted an incredible 16,160 fish nests in photos and videos," said Autun Purser, a biologist from the Alfred Wegener Institute in Germany and lead author of the report.
But after analyzing the images, the scientists estimated that this colony covered an area of at least 240 square kilometers, approximately that of the island of Malta, and they put the number of 60 million nests.
An “absolutely fascinating” discovery
These nests have been identified between 400 and 500 meters deep.
All belong to the same species: Neopagetopsis ionah, a fish well adapted to these difficult living conditions.
"The idea that such a large icefish breeding area in the Weddell Sea has gone undiscovered is absolutely fascinating," Autun Purser said.
Now, scientists hope that this discovery will help advance the initiative to create a marine protected area (MPA) within this area.
Indeed, launched in 2016, this marine conservation project has not yet been completed.
