TLDR
Male lobsters responded more frequently to water from a tank with a recently moulted mature female lobster than to water with a nonmoults mature female, and it is possible that moults females release a sex attractant (pheromone).Abstract:
Of 17 amino acids and other organic compounds tested at high concentration, 13 elicited feeding and walking responses in lobsters significantly greater than those elicited by seawater controls, but only 7 of 29 were stimulatory at low concentrations (alanine, beta alanine, glutamic acid, proline, succinic and malic acids, and tyrosine) Fourteen of 15 mixtures of 2–9 amino acids were stimulatory There may have been potentiation in mixtures with cysteine HCl, lysine, glycine HCl, and methionine and antagonism in some with alanine and arginine Freshly prepared seawater extracts of cod, shrimp, and lobster muscle were more stimulatory than any of the compounds or mixturesMale lobsters responded more frequently to water from a tank with a recently moulted mature female lobster than to water from a tank with a nonmoulted mature female or a moulted or a nonmoulted male It is possible that moulted females release a sex attractant (pheromone)read more

Field Observations of Social Behavior, Shelter Use, and Foraging in the Lobster, Homarus americanus.
TL;DR: The results suggest that much of the time that resident lobsters spend outside shelters is used to remain familiar with their constantly changing physical and social environment.

TL;DR: It appears that intact lobsters orient in odor space by tropotaxis principally using aesthetasc receptor input, and lobster with unilaterally ablated lateral antennules and blocked walking leg receptors turned preferentially toward the side of the intact antennule.
