At present, there are sturgeons specially used for breeding in China. Sturgeon is a kind of delicious food for all ages because of its thick meat and soft bones. Moreover, caviar made from sturgeon eggs is one of the three delicacies in the world, which is basically in short supply in the market. The selling prices are different in different markets and regions. Please go to the local monopoly market for details.
Acipenser sinensis is not allowed to enter the consumption link, and is not allowed to circulate and sell. Farmers and restaurants must have a franchise license to legally buy and sell this kind of artificially cultured fish, namely, the Domestication and Breeding License for Aquatic Wild Animals and the Operation and Utilization License for Aquatic Wild Animals. In addition to obtaining the license, restaurants have to pay the protection fee for aquatic wild animals.
Processing flow of caviar
1, sturgeon sexual maturity is very slow. Generally, the first batch of sturgeons can reach sexual maturity after seven or eight years of artificial breeding, and the female fish can be cut open to take eggs after sexual maturity.
2. It is best to have a series of tests before taking eggs, and the fish that pass the test can take eggs.
3. Fish eggs will be entrained with fat after they are taken out, so the fat should be removed and washed with water, and then the caviar should be screened and classified.
4. Then the salt is added. After simple stirring and pickling, the vacuum filling is completed, and the whole processing process is relatively simple.
5. After caviar is processed, it needs to be preserved at a very demanding constant temperature. Usually, some manufacturers will freeze caviar first and then thaw it when it is shipped. Although the cost is reduced, the taste of caviar is also discounted. Therefore, the freshest caviar can usually be eaten in the mature places of cold chain logistics in China.
