January 3, 2017 — When Virginia closed its winter dredge fishery in 2008, waterman Clay Justis turned his attention from catching crabs that season to collecting the gear that captures them.
He was one of several watermen hired under a program that taught them to use sonar to find and remove lost and abandoned fishing gear, primarily crab pots, littering the bottom of the Bay.
“As a waterman, I knew there was stuff on the bottom, but when I turned the machine on, I was like, ‘Wow!’” said Justis, who fishes out of Accomack on the Eastern Shore.
Out of sight in the Bay’s often murky water, crab pots lay scattered all over the bottom, the sonar showed — along with other fishing gear such as gill nets, and all manner of trash, even a laundry machine.
But the so-called “ghost pots” are a special concern because the wire mesh cages with openings to draw crabs in but not let them out can continue to catch — and kill — crabs and fish for years. They are taking a bite out of both the crab populations and the wallets of watermen. More often than not, Justis noted, the derelict pots he pulled up had something in them. “You’ve got fish, you’ve got crabs, you’ve got ducks. All kinds of things,” he said. But, he added, “most of the time, they are dead.”
Concern about delict crab pots in the Bay has been growing for a decade, and a new report for the first time attempts to estimate their Baywide impact. It found that more than 145,000 pots litter the bottom of the Bay — a number the report authors consider to be conservative.
Each year, the report estimated that those pots kill about 3.3 million crabs, 3.5 million white perch, 3.6 million Atlantic croaker, and smaller numbers of other species, including ducks, diamondback terrapins and striped bass.
The number of crabs killed amounts to 4.5 percent of the 2014 Baywide harvest, the report said. Nor is the problem limited to the Bay. Studies have found similar problems with fisheries that use “trap” devices to catch crabs and lobsters globally.
“It’s an issue that, around the country, folks may not be aware of unless you live close to an area where commercial fishing is a way of life,” said Amy Uhrin, senior scientist with the National Oceanic and Atmospheric Administration Marine Debris Program, which funded the study. “It is one of those ‘out-of-sight, out-of-mind’ issues.”
