BOSTON – A baffling disease that makes lobsters ugly, but not
inedible, has crept northward from the Buzzards Bay hotspot where
it’s afflicted lobsters for several years.

The numbers of infected lobsters are far too tiny to cause panic, but
researchers and lobstermen are weary of the disease’s progress. The
disease doesn’t affect the meat, but a lobster with a corroded,
blackened shell is a tough sell.

“You go and spend $8 for a lobster, you want a good-looking lobster,”
said Edward Heaphy, a lobsterman of 50 years from Dover, N.H.

In 1998, diseased lobsters began filling traps in the Buzzards Bay
area, off the coast of southeastern Massachusetts. Almost a quarter
of all lobsters sampled by the state in the bay that year had the
disease, known as shell burn.

In the years since, the diseased lobsters were found in lesser
numbers in Cape Cod Bay and Boston Harbor. Last year, according to
preliminary numbers, 3 percent of lobsters caught off Salem and Cape
Ann had the disease — the first time since sampling began there in
2000 that any infected lobsters were recorded.

“We’ve seen, year by year, a slow, steady progression northward,”
said Bob Glenn, a biologist leading the coastal lobster studies at
the state Division of Marine Fisheries.

Arthur Sawyer, a second generation Gloucester lobsterman, said he’s
spotted a couple diseased lobsters in the last year or two, but
added, “You’re still talking about nothing.”

He said the disease is worth watching because of its mobility and
unexplained cause.

“To say whether it’s going to get worse or not, nobody knows,” Sawyer
said. “Those guys got creamed down there” in Buzzards Bay.

The state’s lobster catch was worth $56.7 million in 2002, the most
recent year for which statistics were available.

The shell disease hasn’t been tied to any mass die-offs, and lobsters
seem to survive it reasonably well, though perhaps in a weakened
state, Glenn said.

The disease is caused by the chitinolytic bacteria that eats chitin,
a cellulose-like substance in the shells. The disease has been around
forever, but the strain that’s hit Buzzards Bay could be new and more
virulent, Glenn said.

“It’s not like livestock where you could inoculate them,” Glenn said.

The disease has yet to significantly affect Maine — where fishery
officials recorded 44 cases of shell disease among 130,000 lobsters
sampled in 2003 — or New Hampshire, where the disease turned up in 43
of 14,308 lobsters.

“Right now, I don’t think it’s anything to be concerned about,”
Heaphy said. “We’re keeping our fingers crossed.”
