[Animals] They film and capture fish at a depth of more than 8,000 meters in Japan

In the Izu-Ogasawara Trench, in southern Japan, the team managed to film the deepest record of a fish.

Scientists filmed and captured snailfish at depths of more than 8,000 meters, setting a new record.

“We have spent more than 15 years researching these deep-sea snailfish; there's a lot more to them than just depth, but the maximum depth they can survive is truly astounding," said Alan Jamieson, a professor at the University of Western Australia (UWA) who worked on the study.

In September 2022, the DSSV Pressure Drop research vessel set out on a two-month expedition to the deep trenches around Japan in the north Pacific Ocean.

The mission was to explore the Japan, Izu-Ogasawara, and Ryukyu Trenches at 8,000m, 9,300m, and 7,300m depths, respectively, as part of a 10-year study of the world's deepest fish stocks.

Jamieson, founder of the Minderoo-UWA Deep Sea Research Center and the expedition's chief scientist, worked with a team from Tokyo University of Marine Science and Technology (Japan) to deploy baited cameras in the deepest parts of the trenches, details Europe Press.

In the Izu-Ogasawara Trench in southern Japan, the team managed to film the deepest record of a fish, the unknown species of snailfish in the genus Pseudoliparis, at a depth of 8,336m.

A few days later, in the Japan Trench, the team collected two fish in traps at a depth of 8,022 m.

These snailfish, Pseudoliparis belyaevi, were the first fish collected at depths greater than 8,000 m and have only been seen at a depth of 7,703 m in 2008.

“The Japanese trenches were amazing places to explore; they are so rich with life, even deep down,” Jamieson said. “We have been researching these deep-sea snailfish for more than 15 years; there is so much more to them than just depth, but the maximum depth they can survive is truly astounding,” he added.
