Idiopathic lesions and visual deficits in the american lobster (Homarus americanus) from Long Island Sound, NY.
In 1999, a mass mortality of the American lobster (Homarus americanus) occurred in western Long Island Sound (WLIS). Although the etiology of this event remains unknown, bottom water temperature, hypoxia, heavy metal poisoning, and pesticides are potential causal factors. Lobsters from WLIS continue to display signs of morbidity, including lethargy and cloudy grey eyes that contain idiopathic l...
متن کاملCadmium and copper metallothioneins in the American lobster, Homarus americanus.
Lobsters were fed cadmium-rich oysters for 28 days, and the induction of cadmium metallothionein and its relation to concentrations of cadmium, copper, and zinc in the digestive gland and gills was determined. A portion of the tissues also was retained for determining the cytosolic distribution of these metals by gel filtration and ion-exchange chromatography. The digestive gland contained a ma...
متن کاملThe olfactory pathway for individual recognition in the American lobster Homarus americanus.
Individual recognition in the lobster Homarus americanus (Milne-Edwards), is based on detection of urine pheromones via chemoreceptors of the lateral antennular flagellum. The specific sensory pathway mediating this recognition is not known. Most of the chemoreceptor cells of this flagellum are found in the unimodal aesthetasc sensilla and project specifically to the glomeruli of the olfactory ...
متن کاملHistopathology of idiopathic lesions in the eyes of Homarus americanus from Long Island Sound.
In 1999, American lobsters, Homarus americanus, from western Long Island Sound (WLIS) experienced a significant mortality. In 2001 and 2004, the eyes and eyestalks of lobsters from WLIS and central LIS were examined for histopathological changes. Idiopathic lesions were identified in the ommatidia and optic nerve fibers proximal to the ommatidia in 29 (56%) of the lobsters from LIS. Lesions wer...
متن کاملInvestigation of Epizootic Shell Disease in American Lobsters (homarus Americanus) from Long Island Sound: I. Characterization of Associated Microbial Communities
Epizootic shell disease (ESD) is a degradative process of the carapace in the American lobster, (Homarus americanus), putatively caused by bacterial infection, and potentially responsible for serious economic losses to the lobster fishery. In Long Island Sound (LIS), ESD is prevalent in lobsters from eastern LIS (ELIS), but almost absent in western LIS (WLIS), presenting a unique opportunity to...
