Live fish caught at record depth

A live deep-sea fish has been caught at a record depth of 2,300m on the hot vents of the Mid-Atlantic Ridge.

Three shrimp species were also pulled to the surface, researchers report in the journal Deep-Sea Research.

Scientists have engineered a new device that allows recovery of live animals under their natural pressure at greater depths than previously achieved.

Next they hope to be able to transfer the animals into an experimental lab to study their normal biology.

“Pressurised recovery has been around for the past 30 years, but this is the deepest fish-capture under pressure - the previous record was 1,400m. This is also the first time pressurised capture has occurred at a hydrothermal vent,” said Dr Bruce Shillito, marine biologist at the Universite Pierre et Marie Curie, Paris, France.
