ON THE MOVEMENTS OF CERTAIN LOBSTERS.

those of other stations. As the lobster pots are not set in large numbers off shore, 
lobsters liberated at Quicks Hole naturally would not stand the same chance of 
recapture toward the south and west that they would toward the north and east, and 
therefore it would seem to be of more than passing interest that from this southern 
point of distribution no lobsters were found to migrate to any considerable distance 
either up the sound toward Woods Hole or across the bay toward New Bedford. 
A second lot, of 140 lobsters, was liberated off Nobsque on the same day as those 
liberated at Quicks Hole. These were quite at liberty to migrate in a northeasterly 
direction, but all reports of their capture came from the southwest. That so many of 
these and other lobsters took a southwesterly course would seem to prove that there 
is in general a decidedly southerly and westerly trend to their migrations, although I 
am not prepared to say whether this is in response to a strong homing impulse, or an 
effort to pass from warmer into colder water, or from shallow into deeper water. The 
proportion of animals captured to those liberated is noteworthy. Of 140 liberated at 
Nobsque, tags were received from 29. The details are as follows:

On the 25th of June 58 lobsters were liberated near the can buoy at the entrance 
of Woods Hole Harbor. Of these, only three were recaptured. No. 928 remained in 
the neighborhood until September 15, when it was captured near the Wepeckets. The 
capture of this and other specimens would go to show that molting does not always 
take place immediately after the eggs have reached maturity, for, if the animals had 
molted, the tags would have been lost.
