Some fishermen are complaining that fish are showing a poor appetite.
While the polypropylene pellets in question are non-toxic, environmentalists fear they will absorb toxins which will then pass into the food chain.
The Hong Kong government is gearing up full momentum to do the clean-up work and assess the impact on food safety and marine ecology.
The Agriculture, Fisheries and Conservation Department, which is responsible for regulating fishing industry, has been closely monitoring the situation and assured the public that no abnormal activity or death of fish has been reported.
However, in thirty seven fish samples the department collected as of 12 August from three affected marine fish culture zones, pellets ranging from 0.4 gram to one gram were found in the stomachs of seven fish samples.
