Semi-dense breeding is provided by 60-90% of fish feed through fertilizer and natural feed and the rest will be manually fed. image: abirishtiaq.blogspot.com. Dauricus Schrenckii is a combination of this fish and Kaluga fish. These sturgeons produce the three main types of caviar, which bear their names. If the size of the caviar is less than 5 mm, it is called blouge, and if its size is greater than 2.5 it is called royal or imperial. Their bills are equipped with ampulla hair cells that can pick up electrical signals from even the smallest marine creatures. Acipenser Nudiventris are usually migrants who come to the Iranian coast for spawning and lay eggs in the Caspian rivers. It resembles a Acipenser Nudiventris fish, but is distinguished by a cut in the middle of the lower lip. Dense breeding which about 50% to 60% of fish feed comes from fertilizer and natural feed, and the rest will be hand-fed. Extensive and non-condensed breeding using natural water products and not using handmade food. Sturgeon, paddlefish and a vast number of relatives from the Chondrostei suborder dominated water systems during the Triassic and early Jurassic Period with some of the greatest diversity of any species group at the time. As black caviar is best known in Iran and southern Russia, red caviar has more supporters in Siberia and the Far East.
