Caviar producer has a 'China Dream'

Kaluga Queen predicts domestic sales increase as 'food of the czars' is now becoming more popular

Spring has come. 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.
