CRUISES 



This report has used the collections from eight 

 cruises made from May 1961 through March 1963 

 ( table 1 ) . Four cruises were made by the Bureau's 

 R/V Black Dougla* (B6203, B6204, B6212, and 

 B6303) ; two by the R/V John N. Cobb through co- 

 operation of the Bureau of Commercial Fisheries 

 Exploratory Fishing Base, Seattle, Wash. 

 (C6208 and C6303) ; and two cruises by the R/V 

 Horizon through cooperation of Scripps Insti- 

 tution of Oceanography (H6105 and H6204). 

 The cruises are briefly summarized below. The 

 stations at which no fish were caught are listed 

 below as "negative tows." The depths of tows 

 in meters and the number of tows (in paren- 

 theses) follow the information on the types of 

 nets used.
