This Monday, December 13, 2010, 22 fishermen died when the South Korean fishing vessel they were on sank off of Antarctica. I did not realize fishing was allowed off of Antarctica other than for research, but it seems that there is a period that began on December 1 that allows for fishing. Although, it is possible they were fishing illegally still, as some species are still protected and illegally fished for poaching profit reasons. Totally unclear about what they were doing and even what happened to cause the boat to sink, as there was not even time for them to send out a distress signal. Luckily, though, there were other nearby fishing vessels and some of the crew (20) was picked up and survived. 5 were found dead and 17 are presumed dead after a search went on for them, as there is little likelihood of them being able to survive more than 10 minutes in the cold waters of the Southern Ocean.
