From Fry to Broodstock: How Aquatir Raises Sturgeon

A tin of caviar is the final result of years of fish farming. Long before packing begins, the work starts with eggs and young fish. At the Aquatir sturgeon complex, breeding follows a full cycle: from eggs to adult fish that produce eggs of their own.

What a full breeding cycle means

Aquatir describes this approach in its account of the production process. Raising successive generations connects the hatchery with the care of adult fish. Young sturgeon are not simply an early stage to get through; their development is part of the farm’s long-term work.

The complex breeds Beluga, Russian Sturgeon, Sterlet and Bester. Bester is a hybrid of Beluga and Sterlet. These fish belong to the same production story, but they should not be treated as if they all grow and mature on an identical timetable.

Two purposes for the young fish

Aquatir identifies two main groups among the fish it raises. One is grown for caviar production. The other replenishes the broodstock: the breeding fish that will provide the next generation.

This distinction explains why a sturgeon farm needs to plan well beyond its next batch of caviar. Keeping breeding fish is an investment in future generations. The work continues even when there is no finished product ready to pack.

Water and care from the start

The young fish grow in water drawn from artesian wells and given additional filtration. Aquatir uses recirculating aquaculture systems, or RAS, in which water circulates through a controlled system. Monitoring and control equipment helps maintain conditions such as temperature and oxygen levels.

Equipment supports the specialists responsible for the fish; it does not make their work unnecessary. The company describes continuous professional supervision throughout rearing, together with feed containing the nutrients and vitamins the fish need.

Why patience matters

Growing sturgeon for caviar takes a long-term commitment. There is no single maturity date that can be applied to every fish. Species, development and the condition of the individual all matter when discussing the path from young fish to adult stock.

For readers interested in how black caviar is produced, this is an important place to begin. The story is not confined to harvesting or salting. It includes maintaining healthy young fish, raising breeding stock and caring for the next generation.
