is assessed as Endangered based on past rate of population decline (EN A2d). While much of the information on past and present abundance of Hong Kong grouper is anecdotal or incomplete, the accounts of the severe decline in numbers from mainland China, the main country where this species occurs after Japan, are worrying enough to support the precautionary approach adopted here. It is estimated that the global population has declined by approximately 63% over the last three generations (i.e., within the last 21 years). It is unlikely that Hong Kong grouper would ever go extinct as mariculturists have successfully bred and raised the species (Tseng and Ho 1988) but the apparent dire state of stocks and continued high fishing pressure on this fish mean it maybe heading for extinction in the wild.
