Epizootic shell disease is a bacterial infection which causes black lesions on the lobsters' dorsal carapaces, reducing their saleability and sometimes killing the lobsters.
Paramoebiasis is an infectious disease of lobsters caused by infection with the sarcomastigophoran (amoeba) Neoparamoeba pemaquidensis.
Paramoebiasis is strongly suspected to play a prominent role in the rapid die-off of American lobsters in Long Island Sound that occurred in the summer of 1999.
Excretory calcinosis in American lobsters in Long Island Sound was described in 2002.
The American lobster (Homarus americanus) is a species of lobster found on the Atlantic coast of North America, chiefly from Labrador to New Jersey.
The most generally attributed factor is an increased duration of warmer temperatures in the bottom of the Long Island Sound.
These hairs are covered with multiple nerve cells that can detect odors.
Larger, thicker hairs found along the edges control the flow of water, containing odor molecules, to the inner sensory hairs.
This organism also causes amebic gill disease in farmed Atlantic salmon, Salmo salar.
Infection occurs throughout the tissues, causing granuloma-like lesions, especially within the ventral nerve cord, the interstices of the hepatopancreas and the antennal gland.
