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.

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 ...

Soft Defect-Tolerant Material Inspired by American Lobsters
ACS Applied Materials & Interfaces, 2020The joint membrane of the American lobster shows an excellent combination of high strength, toughness, and defect tolerance due to the periodic helicoidal stacking of the fiber layers that are connected by a weak continuous matrix. Inspired by the joint membrane of American lobsters, we simply use nonwoven fabrics and silicon rubber to fabricate a ...

Controlling Growth And Reproduction In The American Lobster
Proceedings of the annual meeting - World Mariculture Society, 1976ABSTRACTSomatic and reproductive growth are antagonistic in the lobster, and it is difficult to manipulate one without affecting the other. High temperature may accelerate ovary maturation but cause ovary reabsorption due to molt cycle acceleration. Sustained high temperature promotes rapid molting but may also interfere with ovary development.

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.

The Exoskeleton of the American Lobster – From Texture to Anisotropic Properties
Solid State Phenomena, 2010The exoskeleton of the crustacean Homarus americanus, the American lobster, is a biological multiphase composite consisting of a crystalline organic matrix (chitin), crystalline biominerals (calcite), amorphous calcium carbonate and proteins. One special structural aspect is the occurrence of pronounced crystallographic orientations and resulting ...

A critique of models of the American lobster fishery
Journal of Environmental Economics and Management, 1986Abstract A number of studies have used the American lobster fishery to raise theoretical and empirical issues in the economic application of Schaefer yield-effort models. The present research shows that both published variants of the Schaefer yield-effort model are poor predictors of landings in the lobster fishery. The analysis suggests that minimum

Plastic pollution affects American lobsters, Homarus americanus
Marine Pollution Bulletin, 2019This paper provides the first record of ingestion of plastic debris by American lobster, Homarus americanus. Plastics particles, identified as rubber pieces, were found in the stomachs of 3 from 17 individuals of lobsters kept in laboratory conditions. Debris had evidence of cuts, what suggest they were actively consumed.
