Snow crab season cancellation costs half of Alaska's yearly budget

The decreasing population of crabs pushed the Alaska Department of Fish and Game to cancel the snow crab season, resulting in a collapse in the economy.

Following a catastrophic population drop, the Alaska Department of Fish and Game cancelled the snow crab season earlier this week. This was the second year in a row that the red king crab season was postponed, leading to a financial disaster for Alaska. The decision cost $3 million in tax revenue for Alaska. It is hoped the halt will allow the crab stocks to rise again.

Commercial trawlers conduct stock assessments at the end of each season. However, due to COVID-19, no survey was carried out in 2020. Then, in 2021, the snow crab experienced the most significant crash ever recorded. One popular idea holds that water temperatures caused the fall.

A chilly pool on the Bering seafloor during the summer becomes home to many little snow crabs. These chilly pools have grown smaller in recent years due to warmer waters and less sea ice, forcing crabs into tighter spaces.

Crabs that live in shells face the risk that interlopers will try to steal their homes while they are otherwise distracted by mating.

That risk is even more pronounced for certain types of hermit crabs, who "remodel" their shells by removing some internal structures.

The renovations make the shells more spacious and desirable, but also more difficult to cling onto, particularly in the throes of passion.

Mark Laidre, an assistant professor of biological sciences at Dartmouth University, began exploring whether the crabs most vulnerable to theft might have evolved longer penises "to facilitate safe sex".

"In theory, longer penises could enable individuals to reach out to sexual partners while simultaneously maintaining a safe grip on their property with the rest of their body, thus safeguarding property against thieves while having sex," Laidre wrote in the study in Royal Society Open Science.

To test the theory, Laidre set about the unenviable task of measuring members -- specifically, seeing how the penises of 328 specimens of various types of hermit crab stacked up.

If his theory was correct, he expected to find that crabs with the remodelled and most covetable shells would have the longest penises, while those with unmodified shells would have slightly shorter ones, and hermit crabs with no shells would be the least generously endowed of all.

He also wanted to rule out other possibilities, including that penis length was based on whether crabs were land or sea-based, or correlated with their overall body size.

The hermit crab with the largest penis relative to body size was the Coenobita species, the only one occupying the remodelled and more vulnerable shell homes.

Crabs with unremodelled homes presented the next longest penises, while those who shed their shells as adults were found to have the shortest of all three types.

Further research could "explore such trade-offs by examining relative weapon and penis size in relation to private property value," Laidre wrote.

Significant repercussions from the snow crab crisis will be felt in Alaska and by crew members who reside in Washington and Oregon. Crabs shape Alaskan villages' economies. The reduction in the snow crab harvest and the end of the red king crab season resulted in a loss of $3 million in tax income, or 50% of Alaska's annual budget.
