ProChaete’s Marine Worms Do Not Carry EMS


On December 18, 2013, Shrimp News carried a report on research by Professor Tim Flegel of Thailand’s National Center for Genetic Engineering and Biotechnology (BIOTEC) saying he believed outbreaks of EMS (early mortality syndrome) could stem from broodstock that have eaten polychaetes carrying a unique strain of Vibrio parahaemolyticus bacteria in their gut, and thus becoming carriers of the disease.


As soon as ProChaete, a farmer of polychaetes and part of the Sea Fresh Industry’s SIINVEST Group, which also includes Belize Aquaculture, saw Professor Flegel’s report it immediately commissioned additional lab tests on its polychaete feeds.


OddGeir Oddsen, CEO of ProChaete, reports, “We have now have the additional test results from the University of Arizona Aquaculture Pathology Lab, and I’m delighted to report that AHPND/EMS was not detected in any of the samples tested.  ...Clearly, there’s still a wide debate around the origins of EMS in shrimp, but we felt that anything we could do to help and reassure our customers is worth doing, so we instructed these additional tests as soon as we read the report of Professor Flegel’s work.  ...An important benefit for shrimp farmers is that ProChaete is growing marine worms in biosecure units in Europe, where there is no shrimp farming, and therefore shrimp diseases do not exist.  In addition to this, as part of the process, our extruded feeds are heated to over 90oC for a specified period, which effectively kills bacteria.”


The marine worms farmed by ProChaete have also been tested to show freedom from the seven shrimp viruses on the OIE list.


ProChaete offers SPF (Specific Pathogen Free) product for all stages of shrimp production from broodstock and first-feeding larvae to growout feeds in a variety of formats and pack sizes.
