Increased aggressiveness in gravid American lobsters, Homarus americanus
Aggressive Behavior, 1999Reports in the literature suggest that gravid female lobsters (Homarus americanus) are more aggressive than non-gravid female lobsters. In an earlier study [Cromarty SI et al. 1998. Biol Bull 194:63–71], we showed that, with one exception, gravid females did not respond to an unfamiliar stimulus with escape swimming.

Impacts of V-Notching the American Lobster
Journal of Shellfish Research, 2010ABSTRACT Little information exists on the effects of lobsters that have been v-notched. To help analyze the results of the North Cape restoration program, which released 1.248 million v-notched females, a controlled v-notching laboratory experiment was conducted to determine whether mortality, shell disease, and the rate of notch loss differed between ...

MATING IN THE AMERICAN LOBSTER
Contributions to Canadian Biology and Fisheries, 1933Observation of 24 cases of mating shows that usually it lasts about 60 seconds, and occurs between males with fairly hard shells and females with very soft shells (less than twelve hours after moulting). Correspondingly the males moult several weeks before the females. Of two males the one larger or superior in combat mates with the female.

OPTICAL SENSOR FOR MEASURING AMERICAN LOBSTER VITALITY
AIP Conference Proceedings, 2011The vitality of the American Lobster (Homarus americanus) is correlated to the total hemolymph protein (THP) in lobster hemolymph (blood). The standard technique for determining lobster vitality is to draw blood from a lobster and measure THP with a refractometer.

Diseases of American lobsters (Homarus americanus): A review
Journal of Invertebrate Pathology, 2011The American lobster fishery is a significant economic driver in coastal communities of North America. Increasingly, the impacts of infectious disease are recognized as important components and factors in the population ecology and subsequent management of the lobster fishery. Both environmental and anthropogenic factors impact marine diseases.

Neuropeptidomics of the American Lobster Homarus americanus
Journal of Proteome ResearchThe American lobster, Homarus americanus, is not only of considerable economic importance but has also emerged as a premier model organism in neuroscience research. Neuropeptides, an important class of cell-to-cell signaling molecules, play crucial roles in a wide array of physiological and psychological processes.

Myogenesis in the thoracic limbs of the American lobster
Arthropod Structure & Development, 2010Newly hatched lobster larvae have biramous thoracic limbs composed of an endopodite, which is used for walking in the adult, and an exopodite used for swimming. Several behavioural and physiological aspects of larval locomotion as well the ontogeny of the neuromuscular system have been examined in developing decapod crustaceans.

Economic Benefits of American Lobster Fishery Management Regulations
Marine Resource Economics, 1986A simulation model is used to compare measures for future management identified in the American lobster fishery management plan; specifically, increases in the minimum legal size and a modest reduction in aggregate fishing mortality are evaluated. The analysis diners from previous work in that the distributional aspects of the alternative management ...

American lobster dynamics in a brave new ocean
Canadian Journal of Fisheries and Aquatic Sciences, 2013Dynamic food webs and climate are changing lobster ecology and management. American lobsters (Homarus americanus) evolved in the North Atlantic under conditions of intense predation from large finfish such as Atlantic cod (Gadus morhua). Lobster’s relatively extended brood period and large larval size result in high per capita pelagic phase survival ...
