Life form / Life stage (?) |

J. Fish. Res. Bd Can. 30: 1819-1824 Van der Meeren G, Støttrup J, Ulmestrand M, Øresland V, Knutsen JA, Agnalt AL (2010)NOBANIS – Invasive Alien Species Fact Sheet – Homarus americanus. – From: Online Database of the European Network on Invasive Alien Species - NOBANIS www.nobanis.org, Accessed 28 November 2011 Comments: Larvae develop through 3 larval stages which resides mostly in the upper 2-3 m of the water column. The eggs are attachment to the pleopods underneath the tail of the female. Juveniles which remain in shelter at the water bottom for the next two-three years. |
Sociability / Life stage (?) |
References (not structured): ASMFC (2000) American Stock Assessment and Peer Review Summary Document. Atlantic States Marine Fisheries Commission Comments: In offshore areas, lobsters (H. americanus) are likely to aggregate in areas with some physical structure, such as a submarine canyon at the southern edge of the continental shelf. |
Reproductive frequency (?) | Iteroparous References (not structured): Talbot P, Helluy S (1995) Reproduction and embryonic development. In: Biology of the Lobster Homarus americanus (Ed. J.R. Factor), Academic Press San Diego, P. 177-216 Comments: Smaller females tend to moult and spawn every second year, while larger females can produce egg-clutches two years in a row before moulting the third year. |
Reproductive type (?) | Sexual References: Van der Meeren G, Støttrup J, Ulmestrand M, Øresland V, Knutsen JA, Agnalt AL (2010)NOBANIS – Invasive Alien Species Fact Sheet – Homarus americanus. – From: Online Database of the European Network on Invasive Alien Species - NOBANIS www.nobanis.org, Accessed 28 November 2011 |
Developmental trait (?) | Brooding References: Van der Meeren G, Støttrup J, Ulmestrand M, Øresland V, Knutsen JA, Agnalt AL (2010)NOBANIS – Invasive Alien Species Fact Sheet – Homarus americanus. – From: Online Database of the European Network on Invasive Alien Species - NOBANIS www.nobanis.org, Accessed 28 November 2011 Comments: Female lobsters mate immediately after a moult, build up the internal egg-clutch during the following year, and spawn the next summer. Fertilized eggs attached to the female's pleopod incubate for a period of 9-10 months. |
Characteristic feeding method / Life stage (?) |

U.S. Department of Commerce. National Technical Information Services, Springfield, Virginia. Comments: The habitat and food preference of the American lobster seems to be similar to the European lobster. Lobster larvae of Hamarus americanus eat a wide variety of prey types with small zooplankton being particularly important to the first two stages. Eggs survive the incubation period by utilizing organic food reserves stored within the egg (Aiken and Waddy, 1985) |
Mobility / Life stage (?) |

Marine Ecology Progress Series Mar. Ecol. Prog. Ser. Vol.103: 265-273, 1994 Comments: The first three larval stages passively drift with the water current while the fourth larval stage (Post larvae) are active directional swimmers. Juvenile lobsters are bottom dwellers although swimming has been observed at this stage. |
