Synopsis: The spatial patchiness at age was measured for Pacific herring,Clupea harengus pallasi, larvae of a small coastal inlet. Lloyd's index of patchiness decreased from 3.8 at hatching to a minimum of 1.5 at 25–30 d and then increased to 2.5 at 50 d. This two-cycle pattern resembles that measured by others for the larvae of other species of schooling pelagic fishes. It differs by being several times lower in magnitude. This is attributed to two factors: (1) a rapid reduction in patchiness from a relatively high level in the demersal egg interval to a lower level in the planktonic larval interval as larvae are released into the water column over a period of 2–4 days, and (2) foraging by larval herring for prey that are larger, more dilute, and less patchy than the prey of other, smaller pelagic fish larvae.
