It’s the foul-smelling runoff from processing the 80-meter (260-foot) factory ship’s valuable catch: Antarctic krill, a paper-clip-sized crustacean central to the region’s food web and ...
As Antarctica cleaved from South America 122 Ma, [18] the Drake Passage formed, fully isolating Antarctica geographically by establishing the Antarctic Circumpolar Current and the Antarctic Polar Front. [18] The cooling of Antarctica's seas prompted a mass extinction of most of the organisms off the coasts of Antarctica and in the Southern ocean.
Many introduced species have already established themselves, [13] with rats a particular threat, especially to nesting seabirds whose eggs they eat. [73] Illegal fishing remains an issue, [23] as overfishing poses a great threat to krill and toothfish populations. Toothfish, slow-growing, long-lived fish that have previously suffered from ...
In 2024 a study [147] was released, dedicated to the impact of fishing and non fishing ships on the coastal waters of the ocean when 75% of the industrial activity occur. According to the study: "A third of fish stocks are operated beyond biologically sustainable levels and an estimated 30–50% of critical marine habitats have been lost owing ...
The Drake Passage, between the southern tip of South America and Antarctic, is infamous as one of the most dangerous journeys on the planet. But why is it so rough – and how can you cross safely?
Moreover, the main fishing grounds are presumed by some researchers to cover the area through which the entire stock of Antarctic toothfish pass. [25] Typically, the fishing season has finished in the area by the end of February and for the remainder of the year, much of the area is covered by sea ice, providing a natural impediment to fishing ...
It is found in the ice-cold seas surrounding Antarctica, sometimes at great depths. Adamussium colbecki is a large, slow-growing scallop that lives on the seabed. The shell consists of a pair of ribbed calcareous valves which enclose the soft body and are joined by a ligament at a hinge.
The blackfin icefish (Chaenocephalus aceratus), also known as the Scotia Sea icefish, is a species of crocodile icefish belonging to the family Channichthyidae. [2] The blackfin icefish belongs to Notothenioidei, a suborder of fishes that accounts for 90% of the fish fauna on the Antarctic continental shelf. [3]
