Figure 4. — Larva mortality rate of the northern anchovy predicted by the model using wind data 

 from April 1984 recorded by NDBO (National Data Buoy Office, NOAA) mooring 46012 located at 

 lat. 37.4°N, long. 122. 7°W. The wind record is typical for the southern California coast in 

 spring, (a) The wind speed and larva mortality rate for the period 1-15 April. Day zero is the day 

 of first feeding for larvae emerging from the yolk-sac stage on 1 April, (b) Same as (a) but for the 

 period 16-30 April, with first feeding beginning on 16 April.
