On the other hand, if the female blue crab population falls below the threshold level, then they are considered to be in trouble, and regulations will be put into place to limit harvesting until their numbers rebound. The target is the level that we want to achieve and maintain-it means that female blue crabs are considered to be stable and sustainable. For the past several years, the CBSAC had used reference points from 2011 to determine the target and threshold levels for the Chesapeake Bay female blue crab population. This information is determined by the annual Bay-wide Winter Blue Crab Dredge Survey, as well as harvest data from the prior year.

This statement is based on a series of biological reference points set by the Chesapeake Bay Stock Assessment Committee (CBSAC), a group of experts from federal and state agencies, and academic institutions from around the Chesapeake Bay watershed.īiological reference points determine what the safe level for harvesting blue crabs would be, to ensure their population remains healthy. The 2021 Blue Crab Advisory Report was released today, sharing the good news that the Chesapeake Bay’s blue crab population is still considered to be healthy- not being overfished or depleted.
