Long-finned koi successfully bred at aquatic improved variety trial farm
In Renhe Village, Bingcun, Meixian, there is a farmer named Qiu Dong. Two years ago, he suffered a natural disaster while growing golden pomelo, and nearly 400,000 yuan of investment was almost completely lost. He then switched to raising grass carp, but an 8-mu pond earned him only about two thousand yuan in a year, unable to make ends meet, and he fell into no small amount of debt, with his finances in dire straits. One day, a fisheries expert appeared and showed him a kind of fry, which brought a turning point in his life. Now, he has become a locally somewhat well-known "fish" farming specialist, with an annual net income of more than 20,000 yuan, and has led three or four neighboring relatively poor villagers to prosper together.
