Maryland watermen could hear soon whether crabbing harvest regulations will be changed. State officials say changes could include higher fall bushel limits for female crabs and opening of a June closure period for female crabs to take advantage of higher June crab prices. The proposed changes are based on results of the annual winter dredge survey. Survey results released earlier this year showed a cold winter killed nearly a third of the bay’s adult crabs. The crab harvest increased last year, but the Department of Natural Resources says it was still below the level set to maintain a healthy population.
