Surely still better than Soylent Green? Even so, I keep thinking that more effective population control would be easier than alternatives driven by desperation.

"VM-thawed samples retained higher levels of free amino acids, particularly those contributing to sweetness and umami, enhancing overall flavor complexity. However, bitterness also increased with extended thawing time and was the highest one among the thawing methods."

SpringerLinkEvaluation of Vacuum Microwave Thawing on Quality and Flavor Profiles of North Pacific Krill (Euphausia pacifica) for Potential Human Consumption - Food and Bioprocess TechnologyUltra-fresh quality frozen North Pacific krill (Euphausia pacifica) were thawed using vacuum microwave thawing (VM) and compared with traditional thawing methods of running water (RW) thawing and ice water (IW) thawing. Samples were stored from 0 to 21 h post-thawing. The metabolic, structural and sensory evaluation changes including pH, ATP-related compounds, free amino acids, color, microstructure, and sensory properties were analyzed. The results indicated that VM thawing effectively maintained pH, with a value of 7.95 at 0 h post-thawing, close to the value of the fresh sample. ATP degradation primarily followed the ATP → ADP → AMP → IMP → HxR → Hx pathway, with VM thawing showing the most pronounced delay in ATP breakdown and the relatively highest accumulation of IMP compared to RW and IW thawing. VM-thawed samples retained higher levels of free amino acids, particularly those contributing to sweetness and umami, enhancing overall flavor complexity. However, bitterness also increased with extended thawing time and was the highest one among the thawing methods. Scanning electron microscopy (SEM) revealed that VM thawing better preserved the structural integrity of myofibrillar proteins, with a clear Z-line visible. VM thawing also minimized color changes, as shown by a smaller decrease in L* and better retention of a*, and achieved higher sensory evaluation scores. Although VM thawing did not inhibit endogenous enzymatic activity responsible for blackening, it significantly shortened the thawing time by 62.48 min compared to IW thawing and improved the overall post-thawing quality of North Pacific krill in the initial thawing period, supporting its potential for human consumption.
This should be a #penguin paradise ⚠️🐧
Chinstrap penguins - named after the thin black line under their chin - come to this area near Coronation Island to nest on the elevated ground. It’s where they raise their chicks, who stay warm and tucked away for about 30 days before waddling off to join a penguin daycare (yes, really), watched over by a few adults from the colony.

But raising chicks takes energy. And for that, they rely on one thing being close by: #krill❗

It’s their main food source - and they need a lot of it.
But now, they’re not the only ones hunting for it.👇
Industrial super trawlers are out here too, hauling up krill by the ton, day and night. Right where the penguins feed..

They can’t fight industrial fishing. But you can!

🔔 Tomorrow, we’re sharing a video update from the frontlines - showing something the krill industry would probably rather keep out of sight.

Watch it. Share it. Help us push for real protection!

The Allankay has arrived in Ushuaia. And now, our crew is complete!
Our CEO Alex has joined, along with scientists and returning crew from past campaigns - experienced, motivated, and ready for what lies ahead.
We’re heading south later in the season than ever before. The seas will be rougher. The fight, more urgent. The stakes are higher than ever.
Our next update will come from #Antarctica. Stay tuned!"

BioMed CentralSpatial and temporal variation of Antarctic microbial interactions: a study around the west Antarctic Peninsula - Environmental MicrobiomeBackground The west Antarctic Peninsula (WAP) is a region of rapid environmental changes, with regional differences in climate warming along the north–south axis of the peninsula. Along the WAP, Palmer corresponds to a warmer region with lesser sea ice extent in the north compared to Rothera ~ 400 km to the south. Comprehensive and comparative, year-round assessments of the WAP microbial community dynamics in coastal surface waters at these two locations are imperative to understand the effects of regional climate warming variations on microbial community dynamics, but this is still lacking. Results We report on the seasonal diversity, taxonomic overview, as well as predicted inter-and intra-domain causal effects (interactions) of the bacterial and microbial eukaryotic communities close to the Palmer station and at the Rothera time-series site between July 2013 and April 2014. Our 16S- and 18S-rRNA gene amplicon sequencing data showed that across all seasons, both bacteria and microbial eukaryotic communities were considerably different between the two sites which could be attributed to seawater temperature, and sea ice coverage in combination with sea ice type differences. Overall, in terms of biotic drivers, causal-effect modelling suggests that bacteria were stronger drivers of ecosystem dynamics at Palmer, while microbial eukaryotes played a stronger role at Rothera. The parasitic taxa Syndiniales persevered at both sites across the seasons, with Palmer and Rothera harbouring different key groups. Up to 62.3% of the negative causal effects were driven by Syndiniales at Rothera compared to only 13.5% at Palmer, suggesting that parasitism drives community dynamics at Rothera more strongly than at Palmer. Conversely, SAR11 Clade II, which was less abundant but persistent year-round at both sites, was the dominant driver at Palmer, evidenced by many (28.2% and 37.4% of positive and negative effects respectively) strong causal effects. Article note: Kindly check first page article notes are correct. Conclusions Our research has shed light on the dynamics of microbial community composition and correlative interactions at two sampling locations that represent different climate regimes along the WAP.
Losing #krill would send shockwaves through the #ecosystem—and beyond.
Here’s why: They’re not just essential food for #whales, #seals, and #penguins. They’re key to our climate. When wildlife feeds on krill, they help transfer carbon to the deep ocean, playing a vital role in stabilizing the climate.
👉 Overfishing krill threatens this balance. Protecting them means protecting life on Earth. 🌏
We’re heading back to protect this fragile ecosystem and take on these relentless trawlers when they least expect it. Your support fuels our mission. Let’s fight for #Antarctica’s future—join us today! https://seashe.ph/SavingAntarctica

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 #NatureCommunications.

The tiny, shrimp-like crustaceans known as krill are the essential food source for #BaleenWhales such as #blues and #humpbacks. To feed, these giant marine mammals take in great gulps of ocean water, filtering krill through bristly mouth structures.

“This study really highlights the need for managers to ensure there is enough #krill left in the #SouthernOcean to feed current whale populations and also enough to support whale recovery,” said study co-author #CassandraBrooks, who earned a doctorate from Stanford’s Emmett Interdisciplinary Program in Environment and Resources (E-IPER) in 2017 and is now an assistant professor in environmental studies at the University of Colorado Boulder.
