ABSTRACTGrowth rates for Homarus americanus have been measured and interrelated in a comprehensive manner to include the required feeding rate, and food conversion efficiency. Feeding rate is a function only of age, and is given by: F = 300 C /θ where F is feeding rate in weight percent per day, θ is age in days, and C is grams of food per gram of ...

Streamer Tag Loss from American Lobsters
Transactions of the American Fisheries Society, 2001Abstract Polyethylene streamer tags are commonly used in field studies of American lobsters Homarus americanus, but the loss rate of this tag and sources of variability in tag loss have not been investigated. By applying a permanent mark on American lobsters in Bonavista Bay, Newfoundland, we estimated that streamer tag loss after 8–12 months was about

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.

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.
