"Of the 9254 American lobsters (Homarus americanus) tagged and released in five inshore and midshore locations off southern Nova Scotia during 1983-87, 1298 (14.0%) were recaptured within 5 yr of release. Mature lobsters (≥ 95 mm carapace length, CL) moved on average significantly greater distances than immature lobsters (<95 mm CL). Most (94%) immature lobsters were recaptured less than 18.5 km (10 M) from the release areas, whereas for mature lobsters this percentage was 59%. Many (22.7%) mature lobsters were recaptured more than 92.6 km (50 M) from the release locations; the farthest distance moved was 539.7 km for a male caught south of Cape Cod 1.4 yr after release. General direction of travel was south with some east and west interchange between inshore and offshore areas such as Crowell Basin, the continental slope of Georges and Browns Banks, the Gulf of Maine and southern Nova Scotia. There was movement of lobsters from east to west and from west to east of the Cape Sable area, the southern tip of Nova Scotia, suggesting there is some mixing between lobster stocks off eastern Nova Scotia and southwestern Nova Scotia. The long distance movement and mixing of mature lobsters suggests that attempts to use tagging information in locating biological boundaries between lobster stocks in the Gulf of Maine, adjoining Continental Shelf, Scotian Shelf and inshore areas of southwestern Nova Scotia and southern end of eastern Nova Scotia may be a difficult task"--Abstract, page iii.
