Traditionally the term caviar refers only to Roe from wild Sturgeon in the Caspian and Black seas

TYPES OF CAVIAR BELUGA

OSSETRA

SERVUGA

STERLET

BELUGA

ITS BASICALLY THE ROE OF STURGEON FISH.

The rarest and costliest is from beluga sturgeon that swim in the Caspian Sea.

Beluga caviar is prized for its soft, extremely large (pea-size) eggs.

Sterlet

small golden sterlet caviar which is rare and was once reserved for Russian, Iranian and Austrian royalty.

Ossetra

Next in quality is the medium-sized, gray to brownish osetra (ossetra)

Servuga

And the last in the quality ranking is smaller, gray sevruga caviar.

Commercial caviar production historically involved stunning the fish and extracting the ovaries.

Another method is extracting the caviar surgically (C section) which allows the females to continue producing roe but this method is very painful and stressful for the fish and is illegal in some countries.

Other farmers use a process called "stripping", which extracts the caviar from the fish without surgical intervention.

A small incision is made along the urogenital muscle when the fish is deemed to be ready to be processed.

An ultrasound is used to determine the correct timing.This is the most humane approach towards fish that is presently available but not all farmers use it due to the lack of knowledge in this field.

Extraction of caviar

Storage Caviar is extremely perishable and must be kept

refrigerated until consumption. Pasteurized caviar has a slightly different texture. It is less perishable and may not require refrigeration before opening. Pressed caviar is composed of damaged or fragile eggs and can be a combination of several different roes. It is specially treated, salted, and pressed.
