Crab Population and Farming Challenges

Scientists at the University of Alabama are researching methods to make soft shell crabs available year-round by inducing molting. The molting process, crucial for crab growth, is threatened by habitat loss and pollution, affecting blue crab populations. The research team has isolated a hormone receptor that inhibits molting and plans to test compounds to block it. Sustainable farming practices are essential to minimize impact on wild populations.

What is the main goal of the research conducted by scientists at the University of Alabama at Birmingham?

• To increase the size of crabs

• To make soft shell crabs available year-round

• To reduce the cost of crabs

• To improve the taste of crabs

Why is the soft shell crab considered a delicacy?

• Because it is cheaper

• Because it is larger than other crabs

• Because it is more colorful

• Because it is more pliable and tender

What has caused the decline in wild blue crab populations?

• Habitat loss and pollution

• Overfishing

• Climate change

• Introduction of invasive species

What is the main challenge faced by those who rely on crabbing for a living?

• Competition from other seafood

• High cost of crab licenses

• Decline in wild crab populations

• Lack of fishing equipment

What is Watson's team focusing on to induce molting in crabs?

• Using genetic modification

• Increasing water temperature

• Isolating a hormone receptor

• Changing the crab's diet

What is the purpose of blocking the hormone receptor in crabs?

• To make crabs more resistant to disease

• To stop crabs from growing

• To induce molting

• To change the color of crabs

What is the potential benefit of inducing molting in crabs year-round?

• It will make crabs more colorful

• It will allow for a constant supply of soft shell crabs

• It will increase the size of crabs

• It will make crabs more resistant to predators

What is a key requirement for a sustainable farming program according to Monterey Bay Aquarium Seafood Watch?

• Increasing the number of crabs caught

• Reducing the cost of crab farming

• Following strict guidelines on the impact on wild populations

• Using artificial habitats for crabs
