Sturgeon is a specialty fish that is gradually becoming known to many people. A few years ago, finding a sturgeon restaurant in the area where I lived was not simple. Now, sturgeon has been widely farmed and developed in many areas of the Northwest. However, the selling price for a kilo of fresh sturgeon is not cheap, about several hundred thousand/kilo. This type of fish is prepared with a number of delicious dishes such as: Sturgeon eggs, sturgeon hotpot or grilled sturgeon… This article is not limited to just dishes, but will have a lot of useful information about this type of sturgeon.

Origin and distribution

This type of fish is native to Asian, European and North American waters. Sturgeon have a length (adult) of about 2.5-3.5m that you can easily see in real life. However, there are some relatives that can weigh more than 1 ton and be over 4 meters long.

This type of fish appeared more than 100 million years ago and is divided into 4 types, 25 species; includes shortnose sturgeon, star sturgeon, white sturgeon, beluga and sterlet. Some species only live in fresh water, but others live in the open sea. During the spawning season, they swim back to the rivers.

Characteristics of sturgeon

Similar to sharks or rays, sturgeon are boneless. Their skeleton is just cartilage (an attractive feature that I like). The fish's body is tube-shaped and consists of 5 rows of spines (all cartilage), the skin is thick, tough, rough in color and has no scales. The small fish's mouth is horizontal, has no teeth, long pointed nose and beard. The color of fish depends on the species, age and farming area.

Sturgeon are bottom-feeding fish, using their wedge-shaped snouts to scour soft mud to eat crustaceans and small fish.

Popular types of sturgeon

Russian sturgeon: Russia is known as having the highest quality sturgeon in the world. Sturgeon in Russia is distributed in Azerbaijan, Bulgaria, Georgia, Iran, Kazakhstan. In addition, they are also found in Romania, Russia, Türkiye and Ukraine also have this type of fish.

European sturgeon: Also known as common sturgeon, Baltic sturgeon or Atlantic sturgeon. They live on all European coasts. This species here can be up to 4 meters long. Currently, due to overfishing, this type of sturgeon is almost exhausted.

There are also other types of sturgeon such as: star sturgeon, lake sturgeon, Beluga sturgeon with different characteristics and living water areas.

In Vietnam, sapa sturgeon are raised mainly in Sa Pa, Lao Cai, Bac Kan… and some northwestern regions. Sapa sturgeon meat is chewy and fatty. There are two types of fish in Sapa: raised for meat and eggs.

What's special about sturgeon eggs?

When looking for sturgeon eggs, there are also many types with “sky-high” prices. Personally, I say above the clouds because you will be extremely surprised to know its selling price. It's not sturgeon meat that the super-rich care about, but sturgeon eggs. Ranked as one of the 10 most luxurious dishes on the planet, 1kg of sturgeon eggs costs about 180 million VND/kg, some up to 1.8 billion VND/kg (According to Dan Tri).

Considered black gold, the aristocratic dish consumes a whole stick of gold at each meal, so sturgeon caviar is only for the super rich to enjoy. In the world, Russian sturgeon eggs are the most famous.

Selling price of sturgeon eggs

Through research, the price of Caviar caviar ranges from 1,000-10,000 USD/kg depending on the quality, size, and shine of each type. The larger the fish eggs and the brighter the color, the more expensive they are.

The most popular today is Sevruga sturgeon with a moderate price (ranging from about 1,000-2,000 USD/kg), producing eggs with bright, dark color and great flavor.

Beluga sturgeon caviar is more premium than the above two types with the usual color being dark gray, large egg grains, very fragrant food, priced at about 8,000 USD/kg.

The highest quality is “Golden Caviar” with amber yellow color. This type is the most expensive because it is extremely rare and has extremely high nutritional value, about 9,000-10,000 USD/kg.

Why are sturgeon eggs so expensive?

The reason why white sturgeon eggs are so expensive is that a white sturgeon must be over 20 years old to start producing eggs.

The process of egg collection and processing is also very rigorous and strict. Large sturgeon are dissected to remove eggs using the abdominal incision method. After being collected, eggs are processed in two ways: traditional salt and thermal salt.

Excellent source of nutrition: Sturgeon eggs add a lot of nutritional value to the human body. Eggs contain many nutrients such as calcium, phosphorus, protein, magnesium, iron and all kinds of vitamins.

– Chinese sturgeon is fat and has a short body, rough black color, very sharp nose. – Chinese sturgeon fish often have many scratches, their abdomen has many red blood streaks, ulcers and the sturgeon often lies motionless rather than swimming. . This cause is inferred to be caused by long-distance transportation. – Choose reputable, quality facilities to ensure safety.
