The fish are rapidly stunned, and the two ovaries are removed by a process called “stripping” that extracts the caviar through a small incision in the fish wall. The female can return to the sea after a cesarean section is performed to extract the caviar. It is also used in traditional Chinese medicine to treat a variety of ailments, including cancer, heart disease, diabetes and arthritis.
Can you get caviar from any fish?
It’s not just the roe you find on top of your food in a restaurant. It is possible to come from any fish in the ocean, but only one species of fish: the salmon. Caviar is made up of two parts: a protein called chitin and a mineral called chromium. Chromium is a naturally occurring element that is found in all living things, including humans.
When you eat a salmon, you’re actually eating a piece of the fish’s skin, which contains a small amount of chromic acid, a compound that gives salmon its color and flavor. The protein that makes up the skin of salmon is called pectin, and it’s the same protein found on the inside of a human’s cheekbone.
This protein is what makes salmon taste and look like salmon—it’s also what gives it the ability to absorb nutrients from the water it swims in. In order for salmon to grow and reproduce, it needs to be able to eat and digest the food it eats. To do this, salmon have a special organ called a gill, located in their mouth.
