wide meteorological or oceanographic change. The latter possibility 

 has, in fact, already been suggested by Nair and Chidambaram (1951) 

 and by Uda (1952). 



With the data at hand, it is not possible now to answer the ques- 

 tion posed by our title. Before the answer is attained, some, at least, 

 of the problems need to be more clearly formulated; data need to be 

 assembled, some of which are published in relatively obscure sources 

 or are not published at all; plans need to be laid and implemented; 

 and, finally, means must be found to promote greater exchange of ob- 

 servations and ideas among fishery biologists and oceanographers who 

 face these common problems. All of these objectives might be best 

 attained through the medium of international conferences.
