RECORD OF JACK MACKEREL EGGS, 1954 



A few eggs were taken in January of this year. Over a third 

 of the eggs were taken in May, the peak month. There is some un- 

 certainty as to when spawning ceased since there were no cruises 

 during September and November. However, only a negligible number 

 of eggs were taken during October and records from previous years 

 are consistent with the supposition that no spawning occurred 

 after October. 



Like 1951, over half of the spawning occurred off California 

 with the largest proportion occurring off southern California. A 

 relatively large number of eggs taken off southern Baja California 

 (station lines 123-157) is indicative of the wide dispersal of eggs 

 during this year. 



The quantitative distribution (annual standard haul totals) 

 of jack mackerel eggs is given in figure 6.
