Kohler has patented a way to massage the eggs out of the sturgeon. First, ultrasound is used to view the eggs. A signaling protein is then given to the fish days before the eggs are ready to be harvested to induce labor.
The eggs are then massaged out of the belly. This allows sturgeon farmers to reuse the same fish to harvest roe multiple times during their expected 60- to 120-year lifetime. The extracted eggs are then put through a calcium-water solution to prepare them to be salted and packed for consumption.
Kohler used the technique at a contained sturgeon farm in Germany to produce cruelty-free caviar, also known as “no-kill” and “correct” caviar. They produced 1,100 pounds in 2013.
The sustainable caviar is being marketed under the name Vivace for $125 an ounce. It’s on the menu at the recently opened California Caviar Co. retail and tasting facility in Sausalito.
But some aren’t impressed with the technique.
“It was gross,” Geno Evans, owner of Anastasia Gold Caviar in Florida told NPR. Evans tried to extract caviar without killing the fish, but found it was too soft. “It wasn’t caviar,” he said.
Many animals with horns can be found on the African continent. Unfortunately, many of these are hunted for their horns. Some species face near extinction purely because they are animals with horns! However, millions of these animals still cover the African savanna. There are many graceful herds of the Bovidae family to appreciate. Here is everything you need to know about animals with horns.
Impressive to watch extracting eggs from sturgeon alive.
