RECORD OF JACK MACKEREL liGGS, 1952 



Spawning began in January, rose to a peak in May and ceased 

 by the end of September. 



A partial regional analysis indicates that the center of 

 spawning was more compact than in 1951 with over 90 percent of 

 the spawning occurring off southern California and northern Baja 

 California (station lines 77-107). The record shows less spawning 

 off central and nortiiern California (lines 40-73) and off central 

 and southern Baja California (lines 110-157). 



The quantitative distribution (annual standard haul totals) 

 of jack mackerel eggs is given in figure 4.
