Figure 2. — Yolk absorption, onset of feeding, starvation, and point of irreversible starvation in Pacific mackerel larvae at 

 19° C: A. Rate of yolk absorption — open circles mean area of yolk-sac, solid circles mean area of oil droplet (mm^). B. 

 Mean length of larvae from hatching through yolk-absorption. C. Percent survival of larvae without food. D. Percent of 

 larvae tested at various times after hatching that had ingested one or more Brachionus plicatilis in a 4-h test period — 

 arrow indicates the 50% threshold for the onset of first feeding. E. Mean number of S. plicatilis per positive stomach of 

 larvae tested at various times after hatching. F. Percentage survival at age 8 d for larvae fed for the first time at age 2.5, 

 3.5, 4.5, and 5.5 d — percentages are plotted at the time food was first added. Bars in A, B, and E represent ±2 SE of mean.
