The giant 100-year-old sturgeon caught a net of Chinese fishermen

"This is the biggest fish we've ever bought in the past two decades , " said a seafood expert.

A Kaluga sturgeon has been captured by fishermen in the Heilongjiang River, near the city of Fuyuan, Heilongjiang Province, China, the CCTV station reported.

The video captured "giant" 100-year-old sturgeon in China.

Giant fish weighs 514kg, 3.59m long, CCTV said.

CCTV's 20.5-day video showed a man spreading his arms to take pictures with the fish but could not touch the fish's tail.

CCTV said it was a female, nearly 100 years old this year. A local seafood agency bought fish from fishermen for treatment and breeding. After that, the agency will release it to nature.

"We will treat the wound so the fish can recover ," said Zhu Zhu, head of the Fisheries Breeding and Breeding Station in the fisheries department. 'After that, we will arrange breeding'.
