fished, at least in part, by the seiners and 

 trawlers (tables 9 and 10). Inshore, from July 

 to November 1931, this brood was replaced 

 by the younger and smaller fish of the 1928 

 brood. By moving offshore beginning in mid- 

 summer, July 1932, the 1928 brood (then 

 4- year-old fish) duplicated the movement made 

 the preceding summer by the 1927 brood. With 



the older and larger individuals of the 1927 

 brood, they dominated the offshore catches of 

 the vessel fishery. Because observations were 

 discontinued at the end of the 1932 season, it 

 was not possible to trace the movement of 

 broods subsequent to 1928 from inshore to 

 offshore fishing regions, but it may be pre- 

 sumed that they made such movements.
