Abstract
Seven elements are described for cultivation of the red abalone, Haliotis rufescens: broodstock management; spawning induction, fertilization, and early development; larval cultivation; forage culture; settlement and early-juvenile-stage cultivation; weaning; and grow-out: Cultivation methods and equipment are described. Spawnable abalones are maintained on a year-round basis. Larvae are cultured in a flow-through apparatus that yields over 90% to the settling stage. A diatom slurry method is used to provide forage to the early benthonic and juvenile stages. Cultivation problems are described. Included are those with bacteria, Vibrio spp., and the maintenance of suitable diatom substrates for juvenile stages.
