- Fishing and whaling in Antartica
- Fishing krill is significant as it is at the bottom of many Antarctic food chains
- Krill and toothfish recieved the largest catch allowances in the Southern Ocean in 2017-1018
- More than half of the Antarctic krill population (up to 70 percent) lives in a relatively small region of the Southern Ocean,
- climate crisis hotspot, and one of the most rapidly changing ecosystems in the Southern Hemisphere.
- several Adélie penguin colonies in the area vanished most likely due to depletion of krill in otehr areas
- Southern fur whales were hunted nearly to extinction
- World Blue whale population is 2-5% of its pre-whaling numbers
- illegal, unreported and unregulated (IUU) fishing
- at peak, 7000 sea birds were killed by long lines
- 1990- 90 vessels were operating
- Toothfish are a target as they grow to 2m but are slow to mature and reproduce so ecosystem slowky replenishes
- Location
- Earth's southern hemisphere
- 98% covered by ice
- Fishing krill is significant as it is at the bottom of many Antarctic food chains
