Waterman hauled up more than 10,000 derelict “ghost pots,” lost fishing nets and other assorted metal from the Chesapeake Bay and its rivers this winter as part of Virginia’s Marine Debris Removal Program.
In total, more than 28,000 ghost pots – abandoned crab pots that litter the Bay’s bottom – have been removed over the past three years. Watermen removed more marine debris this year than in either of the last two years.
Ghost pots inadvertently trap and kill crabs, fish and other wildlife. Scientists have determined that each functional ghost pot can capture about 50 crabs a year. Ongoing research suggests 20 percent of all the crab pots set in a year are lost, primarily due to storms or boat propellers.
This year, a total of 9,970 ghost pots were recovered. In addition, 52 lost nets and 532 other pieces of junk were hauled up, including a jon boat, a portable generator frame and a large metal crate used to transport hunting dogs.
The recovered crab pots were found to have captured more than 11,000 animals, including thousands of crabs, as well as turtles, fish, eels and whelks. More than 27,000 animals, many already dead, have been found in ghost pots retrieved since 2008.
The removal program, funded by NOAA through the Virginia Marine Resources Commission and administered by the Virginia Institute of Marine Science (VIMS), pays out-of-work watermen to use side-imaging sonar units to detect and retrieve ghost pots and other marine debris. It is the first and largest program of its kind in the United States.
