Bering Sea Snow Crabs Quiz

What is the reason behind the disappearance of 10 billion snow crabs from the Bering Sea?

• Migration to a new home

• Starvation caused by warmer water temperatures

• Predation by other fish species

• Overcrowding on the eastern Bering Sea shelf

What did the study published by NOAA researchers conclude about the snow crabs?

• They migrated to colder climates

• They suffered from a massive mortality event

• They adapted to warmer water temperatures

• They were affected by overcrowding

What did the NOAA team search for when trying to find the missing snow crabs?

• Evidence of crab migration

• Evidence of predation by other fish species

• Evidence of overcrowding

• Evidence of adaptation to warmer water temperatures

What was the root cause of the snow crab die-off in the Bering Sea?

• Cooking alive in warm water temperatures

• Starvation caused by increased caloric needs

• Predation by Pacific cod

• Overcrowding on the eastern Bering Sea shelf

What effect did the two-year marine heat wave have on the snow crabs?

• Decreased caloric needs

• Decreased competition from other species

• Increased food supply

• Increased starvation and competition

What did the study authors conclude about the snow crab mortality event?

• It was caused by marine heatwaves globally

• It was caused by overcrowding on the eastern Bering Sea shelf

• It was caused by starvation and reduced spatial distribution

• It was caused by adaptation to warmer water temperatures

What is the next existential crisis for fisheries according to the study authors?

• Overcrowding on the eastern Bering Sea shelf

• Climate change

• Migration to colder climates

• Predation by other fish species

What is the expected long-term impact of Bering Sea warming on the snow crab population?

• Migration to colder climates

• Decreased competition from other species

• Increased ice coverage

• Decreased presence in the eastern Bering Sea

What caused the accelerated metabolism and dire food shortage for the snow crabs?

• Decreased caloric needs

• Decreased competition from other species

• Increased ice coverage

• Overcrowding on the eastern Bering Sea shelf

What did the study authors state about the impact of climate change on the snow crab population?

• It will lead to migration to colder climates

• It will lead to decreased ice coverage

• It will lead to decreased competition from other species

• It will lead to increased overcrowding
