Warmer Winters Could Lead to Longer Blue Crab Season in Chesapeake Bay

Scientists from the University of Maryland Center for Environmental Science are predicting that warmer winters in the Chesapeake Bay will likely lead to longer and more productive seasons for Maryland’s favorite summer crustacean, the blue crab.

Researchers examined data on increasing temperatures in the Chesapeake Bay and predictions for continued warming. They found that winters will be up to 50% shorter by 2100, and overwinter survival of the blue crab will increase by at least 20% compared to current conditions.

“Blue crabs are a climate change winner in the bay. As the bay gets warmer they will do better because they are a more tropical species,” said study co-author and Professor Tom Miller of the University of Maryland Center for Environmental Science. “We always hear about those species that are going to struggle or move. Blue crab are going to do better.”
