Abstract

Red abalone, Haliotis rufescens, populations were sampled on 155 transects at five locations along the Mendocino and Sonoma County coast in September 1986. Although abalone occurrence was highly variable, the highest abundance usually occurred in relatively shallow nearshore areas. Size compositions were dominated by large, old abalone with all locations having 50% or more abalone larger than the recreational minimum size. Densities of red sea urchins, Strongylocentrotus franciscanus, on the transects were also variable, but high urchin abundance tended to occur at greater depths than high abalone abundance. (Document has 72 pages.)
