Caviar Company Demonstrates Sustainable Aquaculture

Lucy Towers, The Fish Site, Nov 19, 2013.

ROMANIA - Romania has a caviar industry dating back nearly 3,000 years but it is an industry that has faced problems with overfishing of sturgeon and findings of toxins and heavy metal in caviar. The Caviar Factory, a company dedicated to sustainable caviar production, now explains how these issues are being overcome, writes Lucy Towers, TheFishSite Editor. 

The Caviar Factory, established in 2009 with the aim of developing innovative technologies for the intensive farming of sturgeon, sources its sturgeon from the river Danube under a section of law which allows fishing for breeder material.

In order to produce sturgeon in the best way possible and with greater control over water conditions, the company currently uses a recirculating aquaculture system (RAS). 

Company owner Daniel Tabacaru told TheFishSite that their RAS aims to imitate natural conditions for sturgeon. The company has achieved this through developing a system based on “mass balance” - types of algorithms in chemistry, biochemistry, hydraulics, thermodynamics.

Mr Tabacaru also noted that the company has a revolutionary biological filter (BIOZEN) which uses zeolites to remove 99.99 per cent of pollutants and heavy metals, including ammonia and other nitrogenous compounds, from the water.  As 99.99 per cent of the nitrogen is retained, the system also has a zero nitrogen footprint.
