The Early Mortality Syndrome (EMS), also known as Acute Hepatopancreatic Necrosis Syndrome is causing high mortalities in various Southeast Asian shrimp farming countries.
The cause of this disease has been linked to the omnipresent Vibrio parahaemolyticus. However this bacterium alone does not have such disastrous consequences. In fact the toxins produced by a virus that has infected the Vibrio (a phage) cause the mortality of the shrimp.
The phage alone is hard to eradicate, hence the proper approach is to reduce the number of Vibrio p. to a minimum.
Independent tests have shown that Vibrio parahaemolyticus is effectively killed by Halamid®. With the effective Halamid® dose being well under the toxic dose to shrimps, Halamid® offers the best possibility to keep Vibrio parahaemolyticus, under control.
Axcentive is continuing tests at the Thailand Kasetsart University following this approach.
Many biocides do not offer the possibility to control Vibrio in the presence of shrimp or fish due to their toxicity at the effective vibriocidal levels required. Halamid® has a low toxicity and is therefore different.
Halamid® is used on a global scale to protect fish and shrimp from pathogenic microorganisms. It destroys bacteria and virus particles in fish tanks, raceways, ponds and cages without harmful effects to the fish. In the USA the FDA has approved Halamid® Aqua for treatment of salmonids against bacterial gills diseases.
