Zealous senior breeder in Tianjin helps nation's fish flourish

Since the 1990s, he has introduced 54 varieties of fish from around the country to Tianjin, where he has helped cultivate them, and promoted his methods nationwide.

The Jinxinwu Crucian, a popular edible household fish, first hit the market after 18 years of research, and better quality farmed fish are now produced nationwide as a result of his efforts.

"A quality fish variety takes decades to produce," Jin said. "Channeling the energy and experience of the research is key to success."

He has made hundreds of attempts to breed hybrid fish. Many failed, but he kept going.

His pool is home to species from different parts of China, including the provinces of Heilongjiang, Henan, Jiangxi and Yunnan.

"My outlook is quite simple. I just want to farm quality fish that are easy to raise, good to sell and delicious to eat," Jin said.
