The Truth Behind The Alaskan Snow Crab Disappearance

Scientists have uncovered that climate change is behind the recent disappearance of a commercially important species, the snow crab.

While it was blamed on climate change, this seems to be the mechanism of the collapse:

The NOAA’s comprehensive study determined that marine heatwaves during 2018 and 2019 were the catalyst for this crab catastrophe. While the water temperature remained within the crabs’ thermal tolerance, it led to an increase in their calorie requirements, leaving them in a perilous situation. The struggle to find sufficient food resulted in a catastrophic population collapse.​

...​

Snow crabs, typically predators of smaller crab species, found themselves in a warmer habitat that attracted new, voracious predators. Pacific cod, usually restricted by temperature barriers, seized the opportunity during the heatwave to prey upon the weakened snow crab population. This significant shift in the food chain further compounded the crisis.​

I thought we might find them in the same place as MH370.

ocean temps are warming .... shocking news!

Meanwhile the lobsters are also disappearing (or emigrating)
