Antarctic Whales’ Remarkable Comeback Is Threatened by Krill Fishing
Huge industrial trawlers are competing for krill – the main food source for whales – in the Southern Ocean, removing vital nutrients from the ecosystem.
TL;DR
- Whale populations in Antarctica, particularly humpbacks, are recovering significantly since the ban on commercial whaling in 1986.
- Industrial trawlers fishing for Antarctic krill, the primary food source for whales, have emerged as a new threat to their recovery.
- Researchers are studying the sustainability of the krill fishery and its impact on whale populations.
- Political deadlock within the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) has hindered conservation efforts to restrict krill fishing in sensitive areas.
- Scientists propose a 30km buffer zone around feeding grounds to protect krill from industrial fishing and support whale recovery.
