At the eastern foot of Erlang Mountain in Tianquan County, Runzhao Fishery Sturgeon Breeding Base, 161 running water fish ponds are lined up one by one. "The water in the pond is the melting water of ice and snow that is drained from the mountains." Li Jun, chairman of Runzhao Fisheries, said that sturgeon is a cold-water fish, and the water temperature must be stable at 12-23 °C all year round, otherwise it is easy to die.

In the fish pond, groups of fry wag their tails and swim in the water, but it will take at least seven years for these fry to grow into sturgeon that can retrieve eggs. "It takes 7-15 years to raise eggs to make caviar." Li Jun said that the mature sturgeon is 2 meters long and weighs more than 200 kilograms. Before the eggs are collected, the annual cost of feed alone for the entire breeding base reaches thousands of dollars. million.
