waters a few miles south of the mouth of 

 Chesapeake Bay in Virginia (fig. 2). 



In the winter of 1932, when the entire body 

 of coastal water from Bodie Island to Cape 

 May (lat. 36° N. to lat. 39° N.) had not cooled 

 to low temperatures as in 1931, the zone of 

 bottom water warmer than 45° F. was far in- 

 shore, resulting in a great increase of area 



in which the scup lived. That the scup scattered 

 widely over the region is indicated by the 

 small catches at spots scattered over the 

 general region and the failure to find large 

 concentrations in any special part of the 

 ground. This temperature change also af- 

 fected the movements of sea bass and fluke 

 because they were not drived as far offshore 

 as in the preceding winter and hence could
