The fish farm complex for the production of black commercial caviar is the most profitable production in the field of industrial sturgeon farming in closed systems.
Caviar is obtained by slaughtering females. In the process of production we also get commercial sturgeon with a hinge from 2 to 6 kg and from 8 kg.
The main differences from the enterprises, designed to obtain only commercial fish, are the need for simultaneous maintenance of breeding stock of different ages, the availability of additional equipment (technological and general industrial) and additional production sites (maintenance of producers and repair young stock, spawning, processing, etc. ).
Accordingly, the area of premises for placing the required equipment is increasing. For example, production of 6 tons of black caviar and 90 tons of commercial sturgeon per year will require about 5,000 m2.
