New England Lobster Research Initiative awards $2.3 million in research and monitoring grants
The New England Lobster Research Initiative has pulled together
some of the most prominent lobster researchers in the country
to address lobster shell disease.
Shell disease disfigures shells, prompts egg-bearing lobsters to
molt prematurely, and can make it difficult for lobsters to shed their
shells. The initiative, funded with a Congressional appropriation obtained
through the efforts of Sen. Jack Reed (D-RI) and Sen. Olympia
Snowe (R-ME), has allocated $2.3 million for nine research and two
monitoring projects that will examine lobsters and their habitats to
determine how the disease affects lobsters and what makes them
susceptible to it. The initiative’s executive committee chair said the
projects will enhance scientists’ fundamental understanding of lobster
biology and disease and provide insights for fishery managers to improve
the health of New England’s most valuable catch.
“These researchers are using cutting-edge technologies to
identify the pathogen that causes shell disease; to determine how
external stressors, such as increasing water temperature or environmental
contaminants, affect lobsters; to see how the disease damages
the lobster’s shell; and to develop a rapid screening technique to
see if a lobster has the disease,” said Kathleen Castro, Rhode Island
Sea Grant Sustainable Fisheries Extension coleader and chair of the
initiative’s executive committee.
“We’ve got to protect our lobster fisheries,” said Sen. Reed.
“This is a major environmental concern, but it is also an important
economic concern. The lobster industry is important to Rhode Island
and New England and is a crucial link to our regional history and
culture. I hope these research teams can identify and mitigate the
problem.”
“Industry, researchers, and fishery managers will hopefully understand
more about the origin of shell disease and then be able to
inform others to help minimize any impacts on the lobster fishery,
therefore optimizing the industry’s health far into the future,” said
Elizabeth Kordowski, then executive director of the Rhode Island
Lobstermen’s Association.

New England Lobster Research
Initiative Funded Proposals:
Two state surveys—one in Rhode Island and one in Maine—were funded to monitor lobsters to see if small lobsters are also
affected by the disease. Working with fishermen and using ventless
traps, which, unlike traditional traps, will prevent sub-legal lobsters
from escaping, state fishery managers will be able to provide realtime
data to researchers in a project requested by lobster fishermen.
Three groups will use different techniques and approaches to
look at the microbiology on lobster shells to identify the pathogen
causing shell disease, and whether or not affected lobsters have suppressed
immune systems.
One project will seek to determine whether different lobster
populations have different susceptibility to the disease, and whether
or not there is a relationship between that susceptibility and
genetic and/or behavioral differences between the populations.
Four projects will examine how environmental stressors—such as increasing water temperature or environmental
contaminants—affect lobsters, whether through interfering
with shell formation or hardening or impacting lobster genetic
expression.
One project will use new techniques to compare shells of
healthy and sick lobsters to see what is changing in the shells
of lobsters with the disease.
