Research over the past decade is drawn on from both South Africa (Hauck19992009; Hauck and Sweijd1999; Tarr2000; Hauck and Kroese2006;2009; Raemaekers et al.2011) and Chile (Stotz1997; Meltzoff et al.2002; Orensanz et al.2005; Gelcich et al.200520062010; Gonzalez et al.2006; Castilla...
A possible association between sea urchins Parechinus angulosus and juvenile abalone Haliotis midae has been monitored since 1989 during diving surveys at three sites on the South-Western Cape, South Africa. In 1994, numbers of sea urchins declined dramatically at two sites (Belly''s Bay and ...
To test the generality and nature of this association, surveys were carried out at five sites between Cape Point and Danger Point in the kelp beds of the South-Western Cape, South Africa. These showed that both species occupy primarily hard substrata, showing preferences for encrusting coralline...
(qualitative observation). The lack of association could be attributed to many factors, including the retention of very low levels of PSTs and ASTs in abalone tissues following previous algal bloom events, phytoplankton “patchiness” resulting in seawater samples that did not contain algal cells, ...

Nonetheless, genetic improvement of the species is hindered by late maturity and long generational intervals. The...

In kelp beds of the South-Western Cape, South Africa, a strong positive relationship exists between the sea urchin Parechinus angulosus and juveniles of the abalone Haliotis midae. Field surveys reported here revealed a positive, but weak, association between this urchin and H. midae recruits ...
Duan Xin and Lu Fang, the director and the associate director of the local Shandong association, who grew up in the most important abalone production locations in Shandong Province, are experts in abalone harvesting. At the first sight on the beach, Li Chen was fascinated by the sublime ...
