  2. Details about crabs • Crabs serve as predator and prey in the Chesapeake bay ecosystem • Can grow up to 9.1 inches • Crabs are keystone creature in Chesapeake Bay food web • 418 million crabs were estimated to be living in the Chesapeake Bay in 2009 • In 2009 there was a 70% increase in male crabs since 2008 • The juvenile (less than 1 year old) crab population was below the historical average of 259 million

  3. The economy crabs create • One third of the nation’s blue crabs come from the Chesapeake Bay • For the past 60 years, blue crabs have dominated the Chesapeake Bay’s commercial fisheries • In 2000, the crab harvest was valued at approx. $55 million

  4. regulations • Minimum size for a soft shell crab is 3 ½ inch • Minimum size for a peeler is 3 ¼ inch April first to July 14th from July 15th to December 15th is 3 ½ inch • Season for hard shell blue crabs is April 1st to December 15th with a minimum size 5 inches April first to July 14th

  5. Environmental issues affecting the industry • Some years, with crab pots, female crabs are being too heavily crabbed that they can not reproduce enough crabs for the next years • With pollution a big factor in the Chesapeake bay it is hard for any species to maintain a large population with it being heavily harvested annually • After reaching a juvenile stage the crabs start to look for a place to live, so they try to find grass or S.A.V.s (submerged aquatic vegetation) to hid until grown up
