We went to #LA last week, and watched a beautiful documentary about #BlueWhales in the #CaliforniaScienceCenter. Beautiful and sad, because this magnificient species is on the brink of extinction due to humans killing hundreds of thousands of them in 20th century. One of the final acts of this senseless tragedy was an illegal and underreported mass killing of thousands of blue whales, including entire remaining population in the Indian ocean, by Russian whalers in 1960s.

There Are Giant #Mammals Alive Today That Were Adults During the American #CivilWar
The #bowheadwhale, a giant, #Arctic-dwelling species bigger than a bus, evidence suggesting they live over 200yr. There are currently bowhead whales swimming around #Alaska that were alive when #MobyDick was written in 1851.
Other large #whales also enjoy relatively long lives; #bluewhales, can reach up to 90 years of age. Nevertheless, none can rival the extreme longevity of the #bowhead.

We were warned! From September 2024. And now the #whales are falling silent!!! And #krill are dependent on whales as much as whales are dependent on krill!
#KrillHarvesting threatens #whale recovery
Soaring human demand for krill in the Southern Ocean poses a challenge to the recovery of whale species once hunted nearly to extinction. Stanford researchers identify the growing food conflict and offer solutions.
September 10th, 2024
"Human harvesting of krill in the Southern Ocean could threaten the recovery of whale species that were nearly wiped out by industrial whaling in the 20th century, according to a Sept. 10 study in Nature Communications.
"The tiny, shrimp-like crustaceans known as krill are the essential food source for baleen whales such as blues and #humpbacks. To feed, these giant marine mammals take in great gulps of ocean water, filtering krill through bristly mouth structures. Booming demand for krill as #FishMeal and #omega3 fatty acid nutritional #supplements, however, could leave whales without enough victuals to sustain even their diminished numbers.
" 'Our calculations suggest an alarming possibility that we might harvest krill to the point where we do real damage to recovering whale populations,' said lead study author Matthew Savoca, a research scientist in the lab of Jeremy Goldbogen, associate professor of oceans in the Stanford Doerr School of Sustainability.
"The results highlight a need for scientists, regulators, and industry to carefully assess the impacts of krill harvesting in the Southern Ocean at current levels before expanding. 'With this study, we want to draw attention to how there likely isn’t enough krill to support fully recovered whale populations, and now on top of that, we’re harvesting krill and plan to harvest more krill in the near future,' said Goldbogen, the study’s senior author
.
Counting on krill"The new research grew out of a prior Stanford study documenting how baleen whales gobble up significantly more krill than scientists had previously estimated. A paradoxical finding of that study was that, as whale populations plummeted by roughly 90% in the Southern Ocean during whaling’s grim heyday, so, too, did krill populations.
"The researchers worked out that #BaleenWhales effectively fertilize the ocean through their prodigious droppings, providing nutrients for the #phytoplankton that krill eat. The upshot: The krill population must have been much larger, perhaps five times greater, than it is currently to have sustained the pre-whaling whale populations in the early 20th century.
" 'Krill is the foundation of the entire Southern Ocean ecosystem. They’re really the only thing that large whales eat down there,' Savoca said.
"In the nearly 40 years since a global whaling moratorium went into place in 1986, some Southern Ocean species – particularly humpbacks – have made an impressive comeback. Yet this recovery has taken place against increasing competition with humans for the whales’ critical food source; over the past 30 years, the krill catch has quadrupled to around 400,000 tons annually and is set to expand further.
"Savoca and colleagues calculated how much krill is left in the Southern Ocean for baleen whales, seabirds, and other predators to eat after industrial krill harvesting at current rates, compared to the estimated amount of krill available before industrial whaling began. 'The basic math makes it pretty clear that the current krill biomass cannot support both an expanding krill fishery and the recovery of whale populations to pre-whaling size,' said Savoca."

To feed, these giant marine mammals take in great gulps of ocean water, filtering krill through bristly mouth structures. Booming demand for krill as #FishMeal and #omega3 fatty acid nutritional #supplements, however, could leave whales without enough victuals to sustain even their diminished numbers.
" 'Our calculations suggest an alarming possibility that we might harvest krill to the point where we do real damage to recovering whale populations,' said lead study author Matthew Savoca, a research scientist in the lab of Jeremy Goldbogen, associate professor of oceans in the Stanford Doerr School of Sustainability.
"The results highlight a need for scientists, regulators, and industry to carefully assess the impacts of krill harvesting in the Southern Ocean at current levels before expanding. 'With this study, we want to draw attention to how there likely isn’t enough krill to support fully recovered whale populations, and now on top of that, we’re harvesting krill and plan to harvest more krill in the near future,' said Goldbogen, the study’s senior author
.
Counting on krill"The new research grew out of a prior Stanford study documenting how baleen whales gobble up significantly more krill than scientists had previously estimated. A paradoxical finding of that study was that, as whale populations plummeted by roughly 90% in the Southern Ocean during whaling’s grim heyday, so, too, did krill populations.
"The researchers worked out that #BaleenWhales effectively fertilize the ocean through their prodigious droppings, providing nutrients for the #phytoplankton that krill eat. The upshot: The krill population must have been much larger, perhaps five times greater, than it is currently to have sustained the pre-whaling whale populations in the early 20th century.
" 'Krill is the foundation of the entire Southern Ocean ecosystem. They’re really the only thing that large whales eat down there,' Savoca said.
"In the nearly 40 years since a global whaling moratorium went into place in 1986, some Southern Ocean species – particularly humpbacks – have made an impressive comeback. Yet this recovery has taken place against increasing competition with humans for the whales’ critical food source; over the past 30 years, the krill catch has quadrupled to around 400,000 tons annually and is set to expand further.
"Savoca and colleagues calculated how much krill is left in the Southern Ocean for baleen whales, seabirds, and other predators to eat after industrial krill harvesting at current rates, compared to the estimated amount of krill available before industrial whaling began. 'The basic math makes it pretty clear that the current krill biomass cannot support both an expanding krill fishery and the recovery of whale populations to pre-whaling size,' said Savoca."

More victims of #ClimateChange and #WarmingOceans. Also, #KrillHarvesting has got to STOP!
Scientists Alarmed as #Whales Suddenly Going Silent
"When you really break it down, it’s like trying to sing while you're starving."

"Researchers are alarmed after noticing a significant drop in the number of vocalizations from #BlueWhales.
"As National Geographic reports, scientists used specialized underwater hydrophones, meaning the aquatic version of microphones, to record and trace the sounds of marine life, allowing them to analyze the impact human activity is having on various species.
"However, as detailed in a study published in the journal PLOS One, devastating heat waves have triggered worrying changes over the past decade, allowing #ToxicAlgae to bloom and undermine food sources for whales.
" 'It caused the most widespread poisoning of marine mammals ever documented,' coauthor and Monterey Bay Aquarium Research Institute biological oceanographer John Ryan told NatGeo. 'These were hard times for whales.'
"As a result, blue whale vocalizations dropped by almost 40 percent, according to the study, with populations of #krill and #anchovy collapsing.
" 'When you really break it down, it’s like trying to sing while you're starving,' Ryan explained. 'They were spending all their time just trying to find food.' "
