Marine Biologists Discover Enormous Breeding Colony of Icefish biology science
In February 2021, a team of researchers aboard the German research vesselspotted numerous nests of the Jonah’s icefish on the seafloor of the Antarctic Weddell Sea., a marine biologist with the Alfred Wegener Institute at the Helmholtz Centre for Polar and Marine Research.
“It is towed on a special fiber-optic and power cable normally at a speed of about one half to one knot, about 1.5 m above the seafloor.”of the eastern flank of the Filchner Trough, comprised of fish nests at a density of 0.26 nests per mIt represents an estimated total of 60 million active nests and associated fish biomass of over 60,000 tons.“The idea that such a huge breeding area of icefish in the Weddell Sea was previously undiscovered is totally fascinating,” Purser said.
