Commercial Fish Industry
Dutrion chlorine dioxide products are applicable in several sections of the fish industry.
Fish Farms
Chlorine dioxide is very effective at low concentration in ponds and fish production
basins. It is a very selective oxidant and reacts mainly with organic substances. The
major advantage of chlorine dioxide in comparison with other oxidants (e.g. hydrogen
peroxide, ozone and chlorine) is its low oxidation power combined with a high oxidation
capacity. At a concentration of about 0.04 mg/l, the bacterial pressure is greatly
reduced without having a negative effect on the biology and aquaculture in the water.
From a concentration of 0.1 mg/l, the ammonia and nitrite levels should be measured
regularly. At higher concentrations (from 0.2 mg/l to 0.5 mg/l), chlorine dioxide is
capable of significantly reducing and/or solving bacterial problems in fish. The
functioning of the biological filter may be (significantly) reduced at these
concentrations.
Processing
Dutrion chlorine dioxide can be used in the production of water and ice that is intended
for processing of any raw fish. When treated ice is used for packing fish or glazing, it
can slowly release chlorine dioxide onto the surface of fish as the ice melts.
Consequently, this helps prevent spoilage and odors during processing and transport.
Fish Markets
Chlorine dioxide maintains the microbial quality of water even in the presence of high
organic loading. It has a positive impact on the quality maintenance and shelf life of
products. Using ice treated with chlorine dioxide helps prevent spoilage and odors of
fish in shops, at markets and in households.
