Juveniles are taken from healthy, not overexploited wild stocks.
The species is carnivorous. The fish-in-fish-out ratio is relatively high, meaning that relatively large volumes of feed are needed to produce one kilogram of scalloped spiny lobster, which could possibly put pressure on populations of other marine species. Farms use biofouling, self-farmed mussels and fish from sustainable and traceable sources.
Juveniles are taken from wild stocks in Indonesia. The operation has a minimal waste discharge impact on the environment, with discharged water undergoing treatment before release into the sea. The risk of escape from the farm is low, as the lobsters are cultivated in tanks within an indoor environment. The use of chemicals is regulated.
The regulatory framework in Hong Kong covers environment impact assessment (EIA), protection of valuable habitat, water pollution, chemical control, environmental monitoring, most of which have been partly effective and is dependent on self-monitoring by fish farms.
