Nonsurgical Live Removal of Caviar
The need for nonsurgical live removal of caviar from the host mother is one of the best ways to help sustain the sturgeon’s population to a level where it can be removed from the endangered species list. This technique is called stripping the roe from its mother.
The reason stripping is now the preferred method for the removal of the roe for human consumption is that the sturgeon then lives on and can produce another batch of eggs. Unfortunately most species of sturgeon only go thru the reproductive cycle once every three years. This is considerable better than the 20 years required for a sturgeon to be hatched then grow to maturity before it can start to produce roe of its own.
The old way of extracting the roe from the female sturgeons was to slice the belly of the fish open and remove the ovaries that contained the unfertilized eggs. There were some fisheries that were stitching up the females after the ovaries were removed so the fish could live on, but with no ovaries to produce the desired caviar, the fish had no more use for the caviar industry or able to reproduce to help keep the population from collapsing.
The process of stripping itself came from the salmon fisheries. There they used to strip the roe and sperm from adults so a new generation of salmon could be raised. To perform this procedure the sturgeon is generally anesthetized. This allows for less harm to come to the roe and the mother.
This procedure is done by hand where a person takes the fish by the tail with one hand. The other hand then applies pressure to the ovaries externally so the roe can flow out. This is then collected and inspected. Because each fish is different and the quality of its roe will vary, each collection process is done in separate containers so the higher quality caviar can early be separated from the lower grade ones.
This practice of stripping has been performed by the fisheries in Iran for some time now. It is also the reason the Iranian Caviar was not banned for human consumption when all other counties were by the Convention on International Trade in Endangered Species in 2005. The reason for the ban in America was purely a political one that most agree with.
The use of nonsurgical live removal of caviar still allows for the harvesting of this delicacy without endangering the lives of the sturgeons that product them. As long as some of the roe are allowed to hatch, the population of all sturgeon species can be maintained and grow so a sustained supply of caviar can exist in the future for human consumption and enjoyment.
South Korea Emerges as Unlikely Source of Caviar
The unfertilized eggs of the sturgeon have made the fish one of the world’s most valuable wildlife resources. Some 90 percent of the world’s caviar comes from sturgeon in the Caspian Sea, but uncontrolled fishing after the collapse of the Soviet Unio…

The rise in popularity of red caviar is due to its abundance and low price. Unlike its more expensive counterpart, the black caviar, this roe is from salmon.
Red caviar is harvested from three specific types of salmon. These are Siberian, hunchback and red salmon varieties in Europe. Each type has its own flavor and is distinctive with the Siberian being considered the best. The American varieties include King salmon, Chum, Sockeye, Pink, Coho and Steelhead.
Most of the red caviar that is found in Europe is produced by Russia and Iran. In America the largest produce is the state of Alaska. Unlike the black caviar that is harvested from wild sturgeons where the roe is taken by splitting the belly open, thus killing the fish, the salmon are harvested in farms. When the roe is taken from these fish farms, the mother is stitched back up so she can continue to produce eggs for harvesting in the future.
Some connoisseurs believe only wild fish produce the best caviar, so there are many producers of red salmon that still catch wild salmon for harvest. Unlike the sturgeon, there is a huge market for salmon meat and the fish is not left to die in the water after the eggs are harvested. There has also been a non-surgical extraction process called stripping that washing the roe out of the salmon that is being used, but many of the nutrients are also washed away with this technique.
The benefits of caviar are more than just being a rich person delicacy. It is also rich in omega-3 fish oils, vitamin B-12 but also high in cholesterol.
Red Caviar is larger than its black cousin, with a vibrant color and unique taste many prefer. It’s abundance along with the proper techniques to keep the species alive will help this product to be available for decades to come.

There are many different types of caviar on the market today. For the delicacy, most connoisseurs and governments consider caviar as the roe from the sturgeon species of fish. The types of sturgeon that are considered to carry caviar are beluga, osetra, and sevrugu.
These types of sturgeons can be found in the Adriatic Sea and the Black Sea at times, but over 85% of the sturgeon populations are in the Caspian Sea. To be considered authentic caviar, the sturgeons that are caught, must have been living in the wild.
Because of the decimation in the population of this species, Russia has begun farming this fish in order to prevent the species population from collapsing and disappearing altogether. The first shipments of this farmed caviar were sent to Europe in January of 2011 and the verdict is still out on how well it was received.
The Almas caviar is from the albino sturgeon and is a light golden color. These eggs are from a fish over the age of 60 years.
The beluga caviar is the largest roe of all caviar and is light grey to black in color. They are the most sought after and rarest of all types of caviar.
The lowest salt content roe are called Malossol. These are naturally low in salt with the content being from 2.8% to 3.0%.
The pasteurized caviar is handled by the same process as milk to kill off any bacteria that might be present. Unfortunately, this pasteurization process changes the taste of the eggs. The advantage is that they last longer before spoiling.
The pressed caviar is from the broken and soft eggs that were damaged in the handling process. These have the highest salt content and are used mainly in cooking.
There are other species of roe that are considered caviar. To distinguish them from the sturgeon variety, the name of the fish species must be present on the label so the buyer is aware it is not from a sturgeon.
The other most popular species for caviar in America and Europe is salmon caviar. These are large red or orange eggs that are dramatically cheaper that their black cousins. The name salmon caviar is on the outside of the cans.
These are the basic types of caviar available on the open market today. If it just says caviar, it is from the sturgeon variety of fish.
