Comparing two simple methods to induce spawning in the New Zealand abalone (paua), <i>Haliotis iris</i>

Abstract

The effectiveness of two stimuli on the spawning success of wild caught Haliotis iris (New Zealand abalone, paua) were compared. Hydrogen peroxide with a sodium hydroxide buffer induced spawning in 43% of the males and 15% of the females tested one week after capture. Ultraviolet irradiation of the sea water was less effective with only 4% of males and no females spawning.
