Ghost Pot Identification and Recovery.

 

    ghost greeting

 

Ghost (crab) pots are commercial or recreational fishing gear that have been lost in the water.  They may continue to fish leading to capture and loss of non-target species (bycatch).  Ghost pots were identified by sonar in the Mullica River/ JC NERR and recovered by diver localization and assisted grapple in BIOL 2175- Scientific Diving class 10/26/2009.
