Excerpt from Shell Disease of Crustaceans in the New York Bight
Early in 1988 reports were received from fishermen about high prevalences of shell erosion and blackened lesions on the carapace or appendages of lobsters and crabs from waters of the New York Bight. Although shell disease had been reported previously in the vicinity of nearshore ocean waste disposal sites, reports in 1988 concerned shellfish populations from deeper waters of the submarine canyons near the Deepwater Municipal Sludge Dump Site (dmsds) hereafter called the 106 Mile Site. Questions were immediately voiced about possible relationships between shell disease and sludge dumping at that site. Immediate concerns focused on economic losses due to the unsightly appearance of diseased shells and claws, and possible impacts of unfavorable publicity on seafood markets.
In response to these reports, epa Region 2 established a Scientific Working Group to analyze shell disease of crustaceans in the New York Bight and elsewhere in the Northeast. The Working Group consisted of federal, state, and university scientists who reviewed available information about the abundance and condition of populations of lobsters and crabs, as well as information on the cause and extent of shell disease.
The primary purpose of the Working Group was to analyze and summarize available data on whether the condition was pollution related, and whether the disease could cause mortality in economically important species at the 106 Mile Site. The Working Group met in November and December 1988, and again in January and February 1989 to review and analyze published and unpublished data on the status of disease and mortality in commercially important crustacean resources, including those from areas beyond the New York Bight. In February an additional meeting was convened by New Jersey Sea Grant to gain information from commercial fishermen and representatives of other organizations.
Data on crustaceans from the continental shelf break, and the 106 Mile Site, were found to be extremely limited. Nevertheless, in order to assess the possible impacts of pollution on commercial species, the Working Group reviewed the available data on lobster, red crab, rock crab, Jonah crab, and blue crab regardless of the geographic source of the data.
