In October 1976, we dived at 11 sites on the east coast of Moresby Island to examine density and size structure of abalone populations in both harvested and unharvested areas. We found abalone density in the harvested areas to be 1.3/m2 , compared with 4.4-10.0/m2 in the unharvested areas. The population size structure varied with exposure. We found smaller abalone in more exposed areas. Wave exposure and competition for food with the red sea urchin are discussed as possible factors leading to their size differences.
