Negative for EMS


In recent weeks, several shrimp farms, mainly in the north of the country, around Pedernales, in Manabi Province, have reported atypical mortalities.  The National Fisheries Institute (INP), part of the Ministry of Agriculture, Livestock, Aquaculture and Fisheries, tested six samples of shrimp from these farms to determine if early mortality syndrome (EMS) was causing the mortalities.  The tests were performed with PCR specific method for AHPNS/EMS.  The results were negative for EMS!


The possible causes of the mortalities: the transition from the rainy to dry season (temperature changes) and poor management of bacteria, pH, oxygen and ammonia in the ponds.


In 2013, Ecuador developed a contingency plan for keeping EMS out of the country, and that plan was also implemented by Peru and Colombia.  The plan forbids the import of any live shrimp into the three countries from countries affected by EMS.
