Lobster Tagging in the Gulf of St. Lawrence

An individual lobster may occasionally move several kilometres in one day, yet the resultant of all the movements of a group of lobsters during the year is an average removal of only about 8 kilometres from their point of liberation. An occasional lobster, however, may have wandered 30 to 40 kilometres away during this time. The lobsters scatter equally in both directions along shore. Females apparently wander further than males. The intensity of fishing is very high in the areas examined, probably about 40 per cent of the larger lobsters being caught during a two month fishing season.
