GUIDE TO TABLES 



Table I* Standardized Haul Factors (S. Factors). Adjusts each haul to 



the comparable standard of 10 cubic meters of water strained per 

 meter of depth fished (see Ahlstrom 1953: 4-6). 



* . . .An asterisk following an S. factor indicates that one 

 or more additional occupancies of the station were made during 

 the cruise. The additional S. factors for these hauls are given 

 in a supplement to table I. 



- ... A dash indicates that the station was not occupied 

 during the cruise under which it appears 



NQ 



Haul not quantitative. 



Table II. Record of Sardine Eggs, 1952. 



Nu mber of normal eggs . „ . Number of normally developing sar- 

 dine eggs. 



Total number of epgs • . . Includes all sardine eggs taken in 

 a sample, whether norr»ml or abnormal. Srrdine eggs were classi- 

 fied as abnormal vrhen the embryos were stunted and misshapen. It 

 is not known whether such abnormalities are caused by a diseased 

 condition of the eggs, by mechanical injury during collection, or 

 by other means. 



The letters A through D are used to designate age categories 

 of eggs: 



A . . . Eggs spawned within 



B . . . Eggs spawned within 



C . . . Eggs spawned within 



D . * • Eggs spawned within 



Unci. . Unclassified eggs. 



24 hours of collection. 

 24.1 to 48 hours of collection. 

 48.1 to 72 hours of collection. 

 72.1 to 96 hours of collection. 

 Deteriorating eggs that could not 



be classified with certainty. 



* . . . Explained under Ave, n* . 



n . . . Total number of eggs in sample. 



Ave , n^. . . Average number of eggs spawned per day. Because 

 of incomplete age categories resulting from hauls having been 

 taken while spawning or hatching was actively taking place, not 

 all age categories were used in determining n', but only those 

 followed by an asterisk.
