2001) suggested that once populations of Haliotis laevigata

Variations in the anti-viral and anti-bacterial activity of Haliotis laevigata
Larvae of the blacklip abalone Haliotis rubra, greenlip abalone Haliotis laevigata
, and their interspecies hybrid are potentially exposed to temperatures similar to those of adult individuals, because it has been suggested that larvae have a low dispersal range and develop in habitats where adults reside (Prince et al.
Effects of micro and macroalgal diet supplementations on growth and immunity of greenlip abalone, Haliotis laevigata
Furthermore, the recruitment of greenlip abalone Haliotis laevigata
on the coast along the southern Australian islands was independent of adult density within 100 m scale but varied depending on the coastal topography, indicating passive transport of larvae by coastal currents (Shepherd et al.
Fertilization success of the oocytes of all treatments was however above the acceptable in vitro fertilization success of 80% reported for Haliotis laevigata
(Babcock & Keesing 1999).
