RECORD OF JACK MACKEREL EGGS, 1951 



Jack mackerel eggs were collected from February until October, 

 although only negligible amounts were taken during September and 

 October (table la). The month of peak occurrence was March, when 

 nearly one-third of the total number of eggs were obtained. 



A partial regional analysis (table lb) indicates that over 

 half the eggs were spawned off California and that very few eggs 

 were spawned to the south of Point San Eugenio (below station 

 line 120). 



Of the four years reported, 1951 may be characterized as 

 having a northern distribution accompanied by early spawning. 



The quantitative distribution (annual standard haul totals) 

 of jack mackerel eggs is given in figure 3.
