2. Materials and methods
2.1. Oysters
Silver-lip pearl oysters (P. maxima), with dorso-ventral height of
150–180 mm(mature) and 45–60 mm(juvenile),were kindly supplied
by Cygnet Bay Pearls (Broome, Australia, 16° 27′ 5″ S, 123° 0′ 31″ E). The
oysters were housed at Kimberly Marine Research Station (KMRS) on
long lines in panels in the open ocean. The oysters were acclimated for
one month prior to experimentation.
