Bubble-net feeding is a cooperative feeding method used by groups of humpback whales. This behavior is not instinctual, it is learned; not every population of humpbacks knows how to bubble net feed. [4] Humpback whales use vocalizations to coordinate and efficiently execute the bubble net so they all can feed. [4]
“Humpback whales eat small fish and krill, NOT seals. While they have very large mouths, their throats are roughly the size of a grapefruit, so they can't swallow something as large as a seal ...
Whales feed at deeper levels in the ocean where krill is found, but return regularly to the surface to breathe. There whales defecate a liquid rich in nitrogen and iron. Instead of sinking, the liquid stays at the surface where phytoplankton consume it. In the Gulf of Maine, the whale pump provides more nitrogen than the rivers. [30]

Two humpback whales were found dead and another seriously injured this year in huge nets used to collect krill for fishmeal and omega-3 pills near Antarctica, The Associated Press has learned.
In 2021 and 2022, four humpback whales were entangled in one of Aker BioMarine’s nets. Researchers have also identified krill fishing and shrinking sea ice as threats to the reproductive rates ...
However, Japanese do eat krill, [55] and krill is also used in large quantities by fish farms as feed. [56] Pauly's report also claims that the locations where whales and humans catch fish only overlap to a small degree, and he also considers more indirect effects of whales' diet on the availability of fish for fisheries.
While krill fishing is banned in U.S. waters due to concerns it could impact whales, seals and other animals that feed on the shrimp-like creatures, it’s been taking place for decades in ...
