Blue Crab Recruitment

Blue crab recruitment is physically mediated.

  • There is a meteorologically forced window of opportunity from April to October
  • Periodic impingements of the loop current and spin-off eddies affect recruitment success

Blue Crab Settlement

  • Settlement was monitored daily from May-October and used as an index of recruitment.
  • Seasonal periodicity is the same from year to year; but the magnitude of settlement is highly variable.
  • Settlement is episodic.
