| Abstract: | An intertidal fish community in Trinidad Bay, Humboldt County, California, was studied between November 1968 and May 1970. The nursery function of rocky tidal pools for juveniles of subtidal fishes was indicated by peaks in indices of seasonally abundant fish species in summer. The proportion of juveniles of seasonal species in the intertidal fish community rose significantly in collections of late spring and summer, to a maximum of 35% of the individuals collected in July. Annual dominance was relatively high due to abundant populations of the tidepool sculpin, Oligocottus maculosus, but two other fish species were also encountered in tidepools every month of the year. |
