The 700 metric tons of sturgeon farmed in East China's Qiandaohu Lake by Kaluga Queen are expected to spawn and produce one of the world's most expensive gourmet delicacies - caviar.
Weighing 10 to 12 percent of a fully mature sturgeon, which is usually 7 to 15 years old depending on the species, these unfertilized roe are to be retailed at a maximum of 180 yuan ($28.6) per gram, more than half of the price of gold.
Kaluga Queen is the world's largest caviar producer, breeding sturgeon in the 573-square-kilometer lake in Zhejiang province.
Founded in 2003 by several former aquaculture researchers from Beijing, Kaluga Queen, named after the sturgeon species dwelling in Northeast China's Heilongjiang province, surpassed Italy's Agroittica Lombarda SpA as the world's biggest producer of caviar in 2015 with its production reaching 45 tons.
"The scale of the research that China has done on the protection of endangered species, particularly the sturgeon — an anadromous fish that is challenged everywhere in the world — "is something we can all learn from", said Goodwin, president of the University of Maryland Center for Environmental Science.
