This study evaluated the efficacy of nanosilver in grouper aquaculture. The commercial nanosilver solution was trailed for antibacterial activity against Vibrio alginolyticus, one of the most serious threats for grouper survival. The in vitro studies showed that nanosilver possessed Minimum Inhibitory Concentration (MIC) value of 8 ppm, Minimum Bactericidal Concentration (MBC) value of 16 ppm and Zone of Inhibition (ZOI) of 14 mm (20 g silver loading). In addition to assessment of antibacterial activity in culture medium, it was also found that the dosage of nanosilver above 8 ppb were effective for growth inhibition of V. alginolyticus in seawater (103 …

Grossly enlarged corallites, which had earlier been interpreted as tumors, epibionts, or parasitic galls, on colonies of deep-sea scleractinians of the genus Madrepora from various Indo-Pacific localities, were recognized as galls in 1996 by Grygier and Cairns on account of the new species of ascothoracidan crustacean, Petrarca madreporae Grygier, they had found inside enlarged corallites from a site in Indonesia. Here we report the confirmatory recovery of living specimens of P. madreporae from an enlarged corallite of a possibly undescribed variant of Madrepora oculata Linnaeus in Japan. Two affected coral colonies were taken by fishermen off Katsuura, Chiba Prefecture, at …
