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 Ahlstron 1953: 4-6). 



Excluded from the table, but included in a supplement, are 

 three categories of hauls: 1) regular stations occupied only 

 once, 2) special stations occupied only once, and 3) extra tows 

 made at regular stations. 



"■ . . . An asterisk follows an S. factor when there is some 

 doubt about the haul being quantitative. 



The following abbreviations appear in Table I: 

 NT - no net tow taken 

 ST - surface tow only 

 NQ - not quantitative 



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

 during the cruise under I'rfiich it appears. 



Table II. Record of Sardine Eggs, 1953. 



Number of normal eggs . . . Nvunber of normally developing sar- 

 dine eggs. 



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

 a sample, whether normal or abnormal. Sardine eg^s were classi- 

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

 is not laiown whether such abnormalities are caused by a diseased 

 ccndition 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 24 hours of collection. 

 B . . . Eggs spawned within 24.1 to i+^ hours of collection. 

 C . . . Ergs spawned within 4S.1 to 72 hours of collection. 

 D . . . Eggs spawned within 72.1 to 96 hours of collection. 

 Unci . . Unqj-assified eggs. Deteriorating eggs that could not 

 be c±assified with certainty, 



"""... Age categories considered to be completely represented 

 in the sample. 



n . . . Total number of eggs in sample.
