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]
Krill is a rich source of protein and omega-3 fatty acids which are under development in the early 21st century as human food, dietary supplements as oil capsules, livestock food, and pet food. [ 77 ] [ 79 ] [ 84 ] Krill tastes salty with a somewhat stronger fish flavor than shrimp.
Krill are another example of a planktivore that may exhibit high levels of domoic acid in their system; these large plankton are then consumed by humpback and blue whales. Since krill can have such a high level of domoic acid in their system when blooms are present, that concentration is rapidly transferred to whales which leads them to have a ...
“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 ...

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 ...
A humpback whale has made one of the longest and most unusual migrations ever recorded, possibly driven by climate change, scientists say. It was seen in the Pacific Ocean off Colombia in 2017 ...
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]
