This is the shocking moment a young woman deliberately killed live fish in a seafood store to buy them at a discounted price.

Surveillance footage shows the customer netting a large bass from a tank, placing it on the floor, and stepping on it in the aquatic section of a supermarket in Foshan, Guangdong Province, China, on August 8.

She then repeated the act with a second large bass before taking both fish to the weighing counter and insisting on paying the lower rate for dead fish, around half the price of live ones.

Staff recognised her from a previous incident on August 1, when she allegedly bought two dead fish but only attached one price label, effectively paying for one and leaving with both.

This time, the cashier refused to sell her the fish. The woman reportedly left the store without saying a word.

After reviewing the CCTV footage, staff discovered she had intentionally killed the fish to obtain the cheaper rate.

The store owner later released the footage as a warning to other shopkeepers.

Store officials explained that live fish are priced higher due to breeding, transport, and potential loss costs. Dead fish, in contrast, are sold at a reduced price to avoid waste.

They added that deliberately killing fish to pay the lower rate causes a direct financial loss.
