Update on CP Prima’s IMNV Antidote


On September 17, 2014, Shrimp News reported that CP Prima, a company that owns huge shrimp farms on the east coast of the island of Sumatra, had found an antidote for the IMNV virus.  Now, thanks to a “heads up” from Zuridah Merican, editor and publisher of AQUA Culture AsiaPacific, I have a little more information on the “antidote”:


George Basoeki, Head of Corporate Communications at CP Prima, said, “Through a long and in-depth process of modern scientific research, CP Prima has found a formula to solve the IMNV virus problem.”  He said the implementation of the solution must be accompanied by tight bio-security, good aquaculture practice and high-quality feed and postlarvae.  “Those are...absolute requirements in ensuring the formula works optimally,” George said.  “The results from repeated experiments showed that the formulation has proven to be effective in protecting shrimp from the virus, as there was no mortality occurred in shrimp in the treatment groups, while in the control groups, the mortality rate was 43 percent.”


Invented by CP Prima, the solution is very easy for shrimp farmers to adopt, but it does require the use of a specially formulated feed and the application of a supplemental liquid into the pond water.  “The formulation is made with natural herbal extracts, which are proven to increase the natural immunity of shrimps to defend against viral infection,” George said.


In the near future, the special formulated shrimp feed and liquid supplement will be produced by CP Prima and sold to other shrimp farms.


Achmad Wahyudi, Vice President of Aquaculture Programs and the Data Centre at CP Prima, said that since experiments started at the beginning of 2013, it has been proven that the IMNV incidence in the company’s farms has been reduced significantly.  The solution has been applied at PT Central Pertiwi Bahari (CPB), a shrimp farm and a subsidiary of CP Prima in Lampung, Sumatra.  Achmad Wahyudi said, “Now the utilization level of CPB’s shrimp farm capacity has reached 85% and the rate of IMNV infection has been very low...below 1%.”  In recent years, Achmad Wahyudi said the virus at the CPB farm made shrimp farming very challenging.  At the height of the IMNV outbreak in 2009-2012, more than 30% of the farm’s ponds were affected by the disease.
