Australia's humpback whale population has surged to 50,000 from a few hundred, highlighting conservation success. However, the key food source, Antarctic krill, is now threatened by industrial fishing, raising concerns for marine ecosystems.
Australia celebrates ‘humpback comeback,’ but a main food source is under threat
A What happened
Australia is celebrating a remarkable recovery of its humpback whale population, which has rebounded to approximately 50,000 individuals from a mere few hundred due to past commercial whaling. This resurgence is seen as a significant conservation success, particularly for the East Coast population. However, this positive development is tempered by the concerning status of Antarctic krill, the primary food source for these whales. Recent lapses in protective regulations have allowed industrial fishing fleets to harvest krill extensively, raising alarms among scientists and conservationists. Krill are essential not only for humpbacks but also for a wide range of marine life, including seals and penguins. The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) is currently debating the restoration of krill protections, emphasizing the urgent need for sustainable management of this keystone species to maintain the health of marine ecosystems.
