This is the shocking moment a large plastic cup was found inside a fish’s stomach in China.

Footage shows a market vendor cutting open the creature’s belly before revealing the trash lodged inside in Yantai, Shandong province on May 5.

The customer Yu was shopping seafood for dinner but saw the fish among the tray with a bizarrely-shaped body so he asked the vendor to open it up.

They were both shocked as the walls of the stomach appeared to have an unusual shape before a white plastic cup was pulled out of it.

Yu said he wanted to raise awareness about marine pollution using the video after the eye-opening incident in the market.

He said: ‘I revealed the video to the public to raise awareness about marine pollution. Plastic is harmine marine life all over the world.’

‘The vendor told me that it was the first time that he took a garbage out of a fish’s stomach so the situation might have become worse now.’

Data from international non government organisation International Union for Conservation of Nature stated that at least 8 million tons of plastic end up in the ocean every year and make up about 80 per cent of all marine debris from surface waters to deep-sea sediments.

Marine animals ingest or are entangled in these plastic debris which caused severe injuries and even deaths.
