Scientific name
Trachinotus blochii
Hong Kong
Production method
Floating net cages
Source of fry



The species uses trash fish or pelleted feed with high content of fishmeal and fish oil. The fish-in-fish-out ratio is high, meaning that large volumes of fish are used to produce one kilogram of pompano. The composition of its feed ingredients cannot be traced.

Ecological effects

This rearing method leads to a high waste discharge due to cages being an open system, severely impacting water quality. Escapes of the species is likely, with a low-to-moderate escape impact. The species is subject to viral and bacterial diseases and can host various parasites. There is an imminent risk of disease/parasite transfer to wild species. Farms are well regulated on the use of chemicals.


The Hong Kong government has a set of fish culture laws that do not cover farm escape. Mariculture in Hong Kong has been developed with little planning and regulation, and needs more effective and specific laws. Data availability is partially limited and lacks monitoring and transparency.
