The circulation facility
The aquaculture plant contains 7 circulations that the sturgeons according to their life cycle and the processing, run through in sequence:
| - 1 Circulation: | egg and incubation as well as parenting preparations |
| - 2 Circulation: | stock fish circulation |
| - 2 Circulation: | sturgeon rearing |
| - 2 Circulation: | caviar production |
The sturgeon production encompasses the breeding facilities, the stock fish circulation and the sturgeon rearing. The stock fish circulation encompasses 80 pools with 4 m2 volume.
The sturgeon rearing circulation consist of 48 pools with 65 m2 volume each.
The caviar processing contains two circulations in which the sturgeon are kept for ca. 4 years until they are ready for slaughter.
This is where the holding station is also found. The sturgeon females are held here 6 weeks and the sturgeon males, 10 days, in colder water with less occupancy before slaughter. The fish are not fed during this time and are nourished by the reduction of their own body fat, through which the taste as well as the meat and caviar consistency is enhanced.
Water and Energy
This facility uses 500 m3 of fresh water per day. The daily fresh water requirement uses ca. 13% of the entire water volume of 3,800 m3. Two wells have been built and a connection to the drinking water system exists. The electric energy needs require 9,500 kWh per day which is created independently from the two connected block heat power stations, from natural gas. In addition there is a connection to the public power supply system in case of emergency (thunderbolt, lightening, etc.).
Water processing
The heart of the circulation technology is the mechanical and biological water processing. The water is cleaned mechanically with lamella and sieve drum filters. Afterwards, the biological filtering begins with bio film reactors in which micro organisms are cultivated (denitrification). Then the water is degassed (the carbon dioxide is removed and oxygen is supplied to the oxidizer.)
The water is thoroughly swirled twice every hour.
The pH balance is continuously measured and controlled, as well as the temperature and the oxygen content.
Water levels in the pools and the pumps are constantly observed. With an on-line monitoring system the entire facility, ca. 800 measuring positions, are controlled every 5 seconds.
When an error indication appears, the operator is informed immediately exactly which type of disturbance, and the location of each disturbance, per PC or cell phone.
Types of Sturgeon
CAVIAR CREATOR raises and processes Siberian Sturgeon “Acipenser baeril”. Furthermore, Belugas and Albino Sturgeon are found in our stock at CAVIAR CREATOR. The rare and valuable Golden Caviar, once reserved for the Tsars, belonged to our last production.
The female sturgeons grow up to their spawning ripeness in the fourth oder fifth year of life – the male sturgeons will be slaughtered earlier. The spawning ripeness of the female sturgeons are determined by ultrasonic examination.
Currently the Belugas and Albinos are not used for caviar- and meatproduction.
Feeding
The feeding management is a determining factor for the success of production, because an overabundance of food remaining in the pool means an unnecessary encumbrance for the water processing. In Demmin, the eating habits of the fish are closely monitored daily by the personnel. Feeding is undertaken by robots that are controlled by computer and feed according to requirements.
Securing Quality: The Caviar-Master
With the engagement of Caviar – Master Vera Andrejewna Kadzhespirova, CAVIAR CREATOR has won contact to the traditional knowledge of the world famous Russian caviar manufacture. The caviar-master is responsible for the control of all work processes from slaughter to the caviar harvest, as well as the training of the employees of this department. Her duty is the quality control of every tin of caviar that leaves this house. |
