Figure 5. — Kennebunkport, Maine, region showing dispersal of recaptured tagged American lobsters. May 1975-September 1977. Number of recaptures given 

 at each recover, point. Shaded area represents percentage of recaptured lobsters that traveled in a given direction (30° bearing intervals). 



20 n.mi. (37.0 km) movement to Schoodic Head by a 96 mm 

 CL female at large 327 d. 



To evaluate directional movement more objectively, com- 

 pass bearings were assigned to all recapture coordinates and 

 grouped by 30° increments (Figs. 5-7). At Kennebunkport and 

 Boothbay Harbor most lobsters were recovered at bearings 

 1 °-30° and 270°-360° from the release areas while only 8.5<Vo of 

 the returns from both areas traveled in other directions. At 



Jonesport there appears to have been more movement in an 

 easterly direction (60°-90°); however, this is somewhat 

 misleading because only 15 of the 184 lobsters that traveled 

 toward the east exceeded 1 n.mi. (1.9 km), the remaining 169 

 lobsters were caught about 1 n.mi. due east of the release site 

 near Nashes Island (Fig. 7). 



In view of the information presented herein, it can be seen 

 that the majority of recaptured lobsters moved inshore at all
