'Golden' fish roe pull 500 million yuan economic output in Zhejiang village

This breeding area of the base is around 600 mu (40 hectares), and the annual output is 200 tons.

However, when Hangzhou Qiandaohu Xunlong Sci-tech Co Ltd was founded in Qiandao Lake in 2003, it nearly went bankrupt due to not being aware that the temperature was not suitable for breeding sturgeon, said staff member Zhang Xuebing.

Now more than 320 villagers have joined the company, introduced by Zhang.

The company is carrying out the digital transformation of the breeding base, and exploring new development paths for aquaculture through the improvement of information technology.

"Unmanned aerial vehicle inspection and photovoltaic panels placed above the breeding pond, generating power which can be used as the power supply required for breeding," said Guo Cheng, a researcher at the company's institute.
